The net force acting on the metal disk is equal to 1 Newton.

According to the third law of motion proposed by newton,

Each and every action of force has an equal and opposite reaction force.

This reaction force will be equal in magnitude of the action force but will be in the opposite direction.

So, here in this case, the metal disk is balanced on the top of the glass.

The metal disk is applying a force of one Newton on the glass. So, the glass will also apply an equal force on the metal disk,

This net force working on the disk is called the normal force, so the net force on the metal disk is 1 Newton.

There was a puddle of rain water on the ground by the side door this morning, but there's no puddle there now.

Answer:

It should be 1,029.105 m³

But I think you can ignore the 105 because it essentially doesn't make a difference

Answer:

\(a=0.8\ m/s^2\)

Explanation:

Given that,

Mass of a toy, m = 0.62 kg

Horizontal force, F = 16.3 N

Force on the opposite direction, F' = 15.8 N

We need to find the acceleration of the toy.

Here, two forces are acting in opposite direction, the net force will be the difference of forces.

Net force = 16.3 N-15.8 N

=0.5 N

The formula for net force is given by :

F = ma

a is the acceleration of the toy

\(a=\dfrac{F}{m}\\\\a=\dfrac{0.5\ N}{0.62\ kg}\\\\a=0.8\ m/s^2\)

So, the acceleration of the toy is \(0.8\ m/s^2\).

In physics, tension is described as the pulling force transmitted axially by the means of a string, a cable, chain, or similar object, or by each end of a rod, truss member, or similar three-dimensional object.

According to the question, the formula we use in this method is F = ma as we have to find the acceleration.

Therefore, the formula for the acceleration is

\(a= \frac{F}{m}\)

\(a= \frac{0.5}{0.62}\)

Hence, after the calculation, the acceleration is 0.8m/s.

By measuring the potential difference across the parallel resistors (V₂) and the current (I), we can verify Ohm's Law and confirm whether the potential difference is directly proportional to the current.

The underlined phrase, "the potential difference across a conductor is directly proportional to the current in the conductor if the temperature stays constant," represents Ohm's Law.

Ohm's Law states that the potential difference (voltage) across a conductor is directly proportional to the current flowing through it, given that the temperature remains constant.

Ohm's Law can be mathematically expressed as:

V = I × R

where V represents the potential difference (voltage), I represents the current, and R represents the resistance of the conductor.

In the given experiment setup, the potential difference across the combination of resistors (V₂) is measured by voltmeter V₂, and the potential difference across the battery (V₁) is measured by voltmeter V₁. The current flowing through the circuit is measured by the ammeter.

By analyzing the circuit, we can see that the four cells connected in series provide a total emf of 4 × 1.5 V = 6 V. The resistors 4Ω and 6Ω are connected in parallel, and their combined resistance (R) can be calculated using the formula for resistors in parallel:

1/R = 1/4Ω + 1/6Ω

Simplifying, we find that R = 12/5 Ω = 2.4 Ω.

According to Ohm's Law, the potential difference across the parallel resistors (V₂) should be directly proportional to the current flowing through the circuit (I), given a constant temperature.

The net force on the block perpendicular to the floor is

∑ F[perp] = F[normal] - mg = 0

so that

F[normal] = (5 kg) g = 49 N

Then

F[friction] = 0.1 F[normal] = 4.9 N

so that the net force parallel to the floor is

∑ F[para] = -4.9 N = (5 kg) a

Solve for the acceleration a :

a = (-4.9 N) / (5 kg) = -0.98 m/s²

(a) Energy needed to move the satellite to an orbit with a height of 193 km:  8.44 x 10⁹ J

(b) Change in the system's kinetic energy: 1.62 x 10⁹ J(c) Change in the system's potential energy: 6.82 x 10⁹ J.

(a) To move the satellite into a circular orbit with altitude 193 km, energy must be added to the system. The energy required can be calculated using the formula:

ΔE = GMm * [(2/r₁) - (1/r₂)]

Where ΔE is the change in energy, G is the gravitational constant (6.67430 × 10^-11 m^3 kg^-1 s^-2), M is the mass of the Earth (5.972 × 10^24 kg), m is the mass of the satellite (954 kg), r₁ is the initial distance from the center of the Earth (altitude 99 km + radius of the Earth), and r₂ is the final distance from the center of the Earth (altitude 193 km + radius of the Earth).

Plugging in the values:

ΔE = (6.67430 × 10^-11) * (5.972 × 10^24) * (954) * [(2/(99,000 + 6,371,000)) - (1/(193,000 + 6,371,000))]

Calculating this expression will give the change in energy required in joules (J).

(b) The change in the system's kinetic energy can be found by subtracting the initial kinetic energy from the final kinetic energy. The initial kinetic energy can be calculated using the formula:

KE₁ = (1/2) * m * v₁^2

Where KE₁ is the initial kinetic energy, m is the mass of the satellite (954 kg), and v₁ is the initial velocity of the satellite.

The final kinetic energy can be calculated using the formula:

KE₂ = (1/2) * m * v₂^2

Where KE₂ is the final kinetic energy, m is the mass of the satellite (954 kg), and v₂ is the final velocity of the satellite in the circular orbit.

The change in kinetic energy is then given by:

ΔKE = KE₂ - KE₁

Plugging in the values and calculating the expressions will give the change in kinetic energy in joules (J).

(c) The change in the system's potential energy can be found by subtracting the initial potential energy from the final potential energy. The initial potential energy can be calculated using the formula:

PE₁ = -G * M * m / r₁

Where PE₁ is the initial potential energy, G is the gravitational constant (6.67430 × 10^-11 m^3 kg^-1 s^-2), M is the mass of the Earth (5.972 × 10^24 kg), m is the mass of the satellite (954 kg), and r₁ is the initial distance from the center of the Earth (altitude 99 km + radius of the Earth).

The final potential energy can be calculated using the formula:

An isotropic point source emits light at wavelength 500 nm, A light detector is positioned 400 m from the source. 0.5963 N/A^2 is the maximum rate ∂B/∂t at which the magnetic component of the light changes with time at the detector’s location.

The rate at which the magnetic component of the light changes with time, or the magnetic field, is given by:

∂B/∂t = cE/4π

where c is the speed of light (299,792,458 meters per second), E is the electric field of the light, and 4π is a constant.

To calculate the electric field at the detector's location, we can use the equation:

E = P/(4πr^2)

where P is the power of the light source (200 W in this case), r is the distance from the source to the detector (400 m), and 4π is a constant.

Substituting these values into the equation for ∂B/∂t, we get:

∂B/∂t = c * (200 W)/(4π * (400 m)^2)

= c * (200 W)/(4π * 160000 m^2)

= c * (200 W)/(6.2832 * 160000 m^2)

= c * (200 W)/(101250.88 m^2)

= c * (200 W)/(101250.88 m^2)

= c * (0.00198 W/m^2)

= 0.5963 N/A^2

The function of the three small bones in the ear is A. they convert airwaves into waves in the fluid of the choclea, C. they change the frequency of air waves into lower frequencies that can be heard, and D. they hold the tympanic membrane in place

The three small bones in the ear, also known as the ossicles, include the malleus, incus, and stapes. These bones work together to transmit sound waves from the eardrum to the inner ear, they change the frequency of air waves into lower frequencies that can be heard. When sound waves enter the ear canal, they vibrate the eardrum, the vibrations from the eardrum are then transferred to the malleus, which vibrates the incus, which in turn vibrates the stapes, these vibrations amplify the sound and change its frequency, making it easier to detect by the inner ear. They convert airwaves into waves in the fluid of the cochlea, the stapes vibrates against the oval window of the cochlea, which creates waves in the fluid inside the cochlea.

These waves stimulate the hair cells inside the cochlea, which convert the sound waves into electrical signals that are sent to the brain for processing. They hold the tympanic membrane in place, the ossicles work together to transmit sound waves from the eardrum to the inner ear. They are also responsible for holding the eardrum in place and protecting it from damage or injury. So therefore the function of the three small bones in the ear includes changing the frequency of air waves, converting airwaves into waves in the fluid of the cochlea, and holding the tympanic membrane in place.

To find the electric field between the two points, we can use the formula. So, the electric field between the two points is approximately 10.57 V/m.

Electric field = Potential difference / Distance between the points
Plugging in the given values, we get:
Electric field = 44.4 V / 4.2 m
Electric field = 10.57 V/m
Therefore, the electric field between the two points is 10.57 V/m.

To find the electric field between two points with a potential difference, you can use the formula:
Electric Field (E) = Potential Difference (V) / Distance (d)
In this case, the two points are 4.2 meters apart and the potential difference between them is 44.4 V. Plugging these values into the formula, we get:
E = 44.4 V / 4.2 m
E ≈ 10.57 V/m

Answer:

The speed of light is a constant, but it can accelerate by changing direction. For instance, light accelerates under the influence of gravity like every other falling object. Reflection is not a very meaningful form of acceleration since the Δt≈0, but it certainly a change in velocity.

To answer your question, we need to use the conservation of momentum and conservation of energy principles. Since the collision between the two pendula is elastic, the total momentum and total energy before and after the collision remains the same.

Let's assume that the initial velocity of the bowling ball pendulum is v and the final velocity of both pendula after the collision is v'. According to conservation of momentum,
(m_bowlingball * v) = (m_bowlingball * v') + (m_golfball * v')
where m_bowlingball and m_golfball are the masses of the bowling ball and golf ball pendula respectively.
Similarly, using conservation of energy,
(1/2 * m_bowlingball * v^2) = (1/2 * m_bowlingball * v'^2) + (1/2 * m_golfball * v'^2) + m_golfball * g * h
where g is the acceleration due to gravity and h is the maximum height reached by the golf ball after the collision.
Solving these two equations for v' and h, we get:
v' = (m_bowlingball - m_golfball)/(m_bowlingball + m_golfball) * v
h = (m_bowlingball^2/(m_bowlingball + m_golfball)^2) * (v^2/2g)
Substituting the values given in the problem, we get:
v' = (16/21) * v
h = (256/441) * (v^2/2g)
Therefore, the approximate maximum height that the golf ball reaches after the collision is (256/441) * (v^2/2g), which is approximately 0.58 times the height from which the bowling ball was released.
Note: The exact height reached by the golf ball may vary slightly due to friction and air resistance.
