A. Forces always come in pairs that act in opposite directions.

Every activity has a corresponding and opposing response, according to Newton's third rule of motion.As a result, forces always work in pairs.Although equal and opposite in nature, reaction and action forces cannot be balanced since they act on separate things and do not cancel one another out.

According to the third law of Newton's Theory of Motion, there is an opposite and equal response force for every applied force.The action-reaction forces are the collective name for these two forces.

Answer:

It's Newton's third law. For every known reaction, there is a equal and opposite reaction.

Explanation:

The mallet which hits the ball with an action force, the ball exerts a reaction force on the mallet as explained by the Newton's third law. Thus, the correct option is 3.

Newton's third law states that for every action (force) in nature there is an equal and opposite force or reaction. An example of third law of motion is that the mallet hits the ball with an action force, then the ball exerts a reaction.

If an object A exerts a force on the object B, then object B must also exert a force of equal magnitude and in the opposite direction back on object A. The law represents a certain symmetry in the nature that the forces always occur in pairs, and one body cannot exert a force on another without experiencing any kind of force itself.

The speed of supernova debris can reach up to 10,000 km/s. In comparison, the Sun's orbital speed around our galaxy is about 220 km/s.

Step-by-step explanation:
1. Note the speed of supernova debris (10,000 km/s) and the Sun's orbital speed (220 km/s).
2. Compare the two speeds: supernova debris is significantly faster than the Sun's orbital speed.

The Kepler supernova remnant is a piece of the Milky Way galaxy's exploding star that was roughly 20,000 light years from Earth. Early astronomers witnessed the supernova explosion that killed the star in 1604; among them was Johannes Kepler, who gave the object its name.

An enormous supergiant star explodes as a supernova. It might have a brightness equivalent to 10 billion suns! The overall energy production might be 1044 joules, which is equivalent to the sun's output during the course of its 10 billion year existence.
Based on this comparison, the galaxy's gravity might not be strong enough to retain the supernova debris if there were no interstellar medium to slow it down. The debris would likely continue to travel at high speeds, making it difficult for the galaxy's gravity to capture and hold onto it.

In medical imaging techniques, higher photon energies are selectively filtered.

Medical imaging techniques such as X-ray imaging and computed tomography (CT) involve the use of photons to capture images of the internal structures of the body. In these techniques, a beam of X-rays or other high-energy photons is directed towards the body, and the photons interact with the tissues and organs to create an image.

To optimize image quality and minimize radiation dose to the patient, selective filtration is employed. Filters are placed in the path of the X-ray beam to selectively remove certain photon energies. The purpose of this filtration is to remove photons that contribute less to image formation and increase the percentage of photons that are more useful for diagnostic purposes.

By selectively filtering higher photon energies, the lower-energy photons that are more readily absorbed by the body tissues are removed. This allows for better visualization of dense structures such as bones, while reducing unnecessary radiation exposure to the patient.

In summary, medical imaging techniques selectively filter higher photon energies to enhance image quality and minimize radiation dose by removing lower-energy photons that are more readily absorbed by the body.

A. It takes about 4 seconds for the stone to hit the bottom of the cliff. B. The horizontal distance the stone strike the ground is 20 m. C. The horizontal and vertical components of velocity of the stone as it hits the ground is 5.0 m/s, and -39.24 m/s (downward) respectively.

A. The time it takes a stone to hit the bottom of the cliff can be determined using the kinematic equation for displacement:

`Δy = viyt + 1/2at²`,

where Δy is the vertical displacement, viy is the initial vertical velocity, a is the acceleration due to gravity, and t is time.The initial vertical velocity of the stone is zero since it was thrown horizontally. Therefore, we have:

Δy = 78.4 m and a = -9.81 m/s² (downward).

Substituting these values, we get:

78.4 m = 0 + 1/2(-9.81 m/s²)t²

t ≈ 4 seconds.

B. The horizontal distance traveled by the stone is given by the formula:

`d = vixt`,

where d is the horizontal distance, vix is the initial horizontal velocity, and t is time.

Since there is no horizontal acceleration acting on the stone, vix remains constant at 5.0 m/s.

Thus, we have: d = 5.0 m/s × 4 s = 20 m.

Therefore, the stone strikes the ground 20 meters from the base of the cliff.

C. The horizontal component of velocity remains constant at 5.0 m/s since there is no horizontal acceleration acting on the stone. The vertical component of velocity can be found using the kinematic equation:

`vf = vi + at`,

where vf is the final velocity, vi is the initial velocity, a is the acceleration, and t is time.

When the stone hits the ground, its final vertical velocity is -vfy (downward), and its initial vertical velocity is zero.

Substituting these values, we get:

-vfy = 0 + (-9.81 m/s²) × 4 s

vfy ≈ -39.24 m/s (downward).

Therefore, the horizontal component of velocity is 5.0 m/s, and the vertical component of velocity is -39.24 m/s (downward).

The skater moves at a 10 m/s speed. The right answer is A.

We must examine the forces operating on the skater in order to calculate their speed. The horizontal force applied to the ground creates the centripetal force, which is pointed in the direction of the circular path's center.

The centripetal force is calculated using the formula F = (mv2) / r, where m is the skater's mass, v is the speed, and r is the circle's radius.

We may convert the skater's horizontal force of 1125 N to the centripetal force as follows:

1125 N = (45 kg * v^2) / 4 m.

We rearrange the equation to find v:

1125 N * 4 m = 45 kg * v^2.

4500 N*m = 45 kg * v^2.

If you multiply both sides of the equation by 45 kg, you get:

100 N*m = v^2.

Taking the square root of both sides gives:

v = 10 m/s.

The reaction in which a disaccharide is broken down into its component monosaccharides is option d. hydrolysis.

The process in which a disaccharide is broken down into its component monosaccharides is called hydrolysis. Hydrolysis is a chemical reaction that involves breaking a chemical bond using water.

In the case of disaccharides, hydrolysis breaks the glycosidic bond that holds the two monosaccharide units together. This reaction requires the addition of water molecules, and it results in the formation of two separate monosaccharide molecules.

Hydrolysis is an important process for the digestion of carbohydrates in the human body. The carbohydrates we consume are typically complex polysaccharides, such as starch or glycogen.

These molecules are too large to be absorbed by the small intestine, so they must first be broken down into their component monosaccharides. This process is facilitated by various enzymes that catalyze hydrolysis reactions.

The name given to it is "terminal velocity".

In reality, it isn't a velocity, and it doesn't happen in free-fall.

Go figure.

The final value of the pressure, assuming constant temperature, is approximately 1.689 atm.

To determine the final value of the pressure when the volume of a gas is increased while the temperature remains constant, we can use Boyle's law, which states that the pressure and volume of a gas are inversely proportional when the temperature is held constant.

Boyle's Law can be expressed as:

P₁V₁ = P₂V₂,

where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume, respectively.

In this case, we have the initial volume V₁ and the final volume V₂. We need to find the final pressure P₂.

Let's assume the initial pressure P₁ is known. Substituting the given values into the equation, we have:

P₁ * V₁ = P₂ * V₂.

Rearranging the equation to solve for P₂, we get:

P₂ = (P₁ * V₁) / V₂.

Now we can calculate the final pressure using the given values of V₁ and V₂:

P₁ = Initial pressure (in some units)

V₁ = Initial volume (in m³)

V₂ = Final volume (0.370 m³)

If we assume the initial pressure (P₁) is known, we can use the equation:

P₂ = (P₁ * V₁) / V₂

Since the temperature remains constant, we can use Boyle's law to relate the initial and final pressures with the initial and final volumes.

Let's assume the initial pressure is P₁ = 2.5 atmospheres (atm), and the initial volume is V₁ = 0.250 m³. The final volume is given as V₂ = 0.370 m³.

Substituting the values into the equation:

P₂ = (2.5 atm * 0.250 m³) / 0.370 m³

The Australian legal system is based on the common law tradition inherited from the British legal system. It operates under a federal system of government, which means that power is divided between the federal government and the states and territories. The legal system consists of both federal and state/territory courts, each with its own jurisdiction.

Courts in the Australian Legal System:

a) High Court of Australia: The highest court in the Australian legal system is the High Court of Australia. It has original jurisdiction in certain matters, such as disputes between states, and it hears appeals from lower courts. The decisions of the High Court are binding on all other Australian courts.

b) Federal Courts: The federal court system includes the Federal Court of Australia, which handles matters related to federal laws, such as bankruptcy, intellectual property, and trade practices. There are also specialist federal courts, such as the Family Court of Australia and the Federal Circuit Court, which deal with family law and general federal law matters, respectively.

c) State and Territory Courts: Each state and territory has its own court system. The highest court in each state or territory is usually called the Supreme Court. These courts have general jurisdiction and handle a wide range of civil and criminal matters. Below the Supreme Court, there are lower courts, such as District Courts, County Courts, Magistrates' Courts, and Local Courts, which handle less serious matters.

Legal Sources in the Australian Legal System:

a) Legislation: Laws in Australia are made by Parliament at both the federal and state/territory levels. Acts of Parliament, also known as statutes or legislation, are written laws that address various areas of law, such as criminal law, contract law, and family law. Legislation is the primary source of law and is binding on all courts.

b) Common Law: The Australian legal system is based on the common law tradition. Common law refers to the body of law derived from judicial decisions made by courts over time. When a court makes a decision on a legal issue, it establishes a precedent that becomes binding on lower courts. Common law principles help interpret legislation and fill gaps where the law is silent.

c) Constitution: The Australian Constitution is the supreme law of the land. It establishes the structure of the federal government and outlines the powers of the Commonwealth Parliament. The Constitution sets out the division of powers between the federal government and the states/territories, as well as certain fundamental rights and freedoms.

d) Case Law: Case law refers to the collection of legal principles derived from court decisions. Courts interpret legislation and apply legal principles to specific cases, creating precedents that guide future decisions. Case law plays a crucial role in the development and interpretation of the law.

Answer:

The maximum possible speed is 4.85 m/s.

Explanation:

The Principle Of Conservation Of Mechanical Energy

In the absence of friction, the total mechanical energy is conserved. It means that :

\(E_m=U+K\) is constant, being U the potential energy and K the kinetic energy

U=mgh

Where m is the mass of the object, g is the gravitational acceleration and h is the height from a fixed reference.

\(\displaystyle K=\frac{mv^2}{2}\)

Where v is the speed.

When the person is at a maximum height of 2 meters, the speed is 0. Thus the mechanical energy is made only of potential energy.

Let's fix the reference for the height to the point where the person is at minimum height (1 m from the ground level). The maximum height with respect to this reference is h=2.2 m - 1 m = 1.2 m.

The potential energy is:

U = m*9.8*1.2

U = 11.76m

When the person is at the minimum (zero) height, the mechanical energy is made only of kinetic energy. Since the mechanical energy is conserved, then:

\(\displaystyle \frac{mv^2}{2}=11.76m\)

Multiplying by 2 and simplifying by m:

\(v^2=2*11.76=23.52\)

Solving for v:

\(v=\sqrt{23.52}=4.85\)

\(\boxed{v=4.85}\)

The maximum possible speed is 4.85 m/s.

The magnitude of the average force exerted on the water by the blade is 99840 N.

The force exerted by the blade can be calculated using the conservation of momentum principle.

The momentum of a body is equal to its mass multiplied by its velocity.The momentum change of the water stream is given bym(vf-vi) = 26.0 kg/s(-16.0 m/s - 16.0 m/s) = -832.0 Ns. The force exerted by the blade on the water is equal and opposite to this momentum change, which isF = (-832.0 Ns)/0.00835 sF = -99840 N. Thus, the magnitude of the average force exerted on the water by the blade is 99840 N.

The energy stored by the capacitor when the current in the circuit is 2.0 mA is 20.0 μJ.


We can use the formula for the energy stored in a capacitor, which is:

E = 0.5 × C × V^2

Where E is the energy stored, C is the capacitance, and V is the voltage across the capacitor.

When the switch is at position b, the capacitor is uncharged, so the voltage across it is 0 V. When the switch is moved to position a, the capacitor starts to charge, and the voltage across it increases as a result. The current in the circuit is given as 2.0 mA.

To find the voltage across the capacitor, we can use Ohm's law:

V = I × R

Where V is the voltage, I is the current, and R is the resistance. The resistance in this circuit is 1 kΩ, so:

V = (2.0 × 10^-3 A) × (1 × 10^3 Ω) = 2.0 V

Now we can calculate the energy stored by the capacitor:

E = 0.5 × C × V^2

We are not given the capacitance, so we cannot find the energy directly. However, we can use another formula that relates capacitance, current, and time:

Q = C × V

Where Q is the charge stored on the capacitor. We know that the capacitor is uncharged when the switch is at position b, so the charge on the capacitor when the switch is at position a is:

Q = C × V

Where V is the voltage across the capacitor, which we found to be 2.0 V. The current in the circuit is 2.0 mA, so the time it takes for the capacitor to charge to this voltage is:

t = Q / I

Where t is the time, Q is the charge on the capacitor, and I is the current. Substituting the values we have:

t = (C × V) / I

We can rearrange this equation to find C:

C = (I × t) / V

We are not given the time, but we can use another formula to find it:

V = V0 × (1 - e^-t/RC)

Where V0 is the initial voltage (0 V in this case), R is the resistance (1 kΩ), C is the capacitance (which we are trying to find), and e is the natural logarithm base (approximately 2.71828). Solving for t:

t = -RC × ln(1 - V / V0)

Substituting the values we have:

t = - (1 × 10^3 Ω) × ln(1 - 2.0 V / 0 V)

Note that ln(1 - x) is undefined for x ≥ 1, so this formula gives us a negative time. This means that the capacitor will never fully charge in this circuit, because the voltage across it would have to exceed the voltage of the battery, which is 3.0 V. However, we can still use the formula we found for C:

C = (I × t) / V

Substituting the values we have:

C = (2.0 × 10^-3 A) × (- (1 × 10^3 Ω) × ln(1 - 2.0 V / 0 V)) / 2.0 V

C ≈ 2.72 μF

Now we can finally calculate the energy stored by the capacitor:

E = 0.5 × C × V^2

Substituting the values we have:

E = 0.5 × (2.72 × 10^-6 F) × (2.0 V)^2

E ≈ 20.0 μJ

Answer:

A malleable material is one in which a thin sheet can be easily formed by hammering or rolling. ... In contrast, ductility is the ability of a solid material to deform under tensile stress.

A battery is an electrochemical device that generates electricity from a chemical reaction. It typically consists of two electrodes, an anode and a cathode, separated by an electrolyte, which is a solution or medium that conducts ions.

The chemical reaction between the electrodes and the electrolyte generates a flow of electrons, which can be harnessed to power electrical devices.The flow of electrons generated by the chemical reaction in a battery is a one-way process and cannot be reversed. When the battery is connected to a circuit, the electrons flow from the anode to the cathode, producing an electrical current.

However, the reverse flow of electrons, from the cathode to the anode, cannot be achieved by simply reversing the direction of the current. This is because the chemical reaction that generates the flow of electrons is not reversible.Different types of batteries use different chemical reactions to generate electricity. For example, alkaline batteries use zinc as the anode and manganese dioxide as the cathode, while lead-acid batteries use lead as the anode and cathode and sulfuric acid as the electrolyte.

Lithium-ion batteries, which are commonly used in portable electronic devices, use lithium ions as the charge carriers and graphite as the anode.In conclusion, a battery is an electrochemical device that generates electricity from a chemical reaction and cannot be run in reverse. The chemical reaction is a one-way process that generates a flow of electrons from the anode to the cathode, producing an electrical current that can be used to power electrical devices.
