Increase in mass and velocity, increases the momentum of a rugby player and a player with more momentum will be difficult to stop and he be of advantage to his team.

Momentum is important in sport, particularly contact sports where collisions are involved. For example rugby, the more momentum a rugby player has the harder it is to stop him.

Momentum is defined as the product of mass and velocity.

P = mv

where;

The massive a player is, the more momentum he will have and also the greater the velocity of the player, the more momentum the player will have.

Thus, increase in mass and velocity, increases the momentum of a rugby player and a player with more momentum will be difficult to stop and he be of advantage to his team.

In the air, pressure waves that propagate as sound. If the sound reaches the ear, it passes through the auditory tube, where it is amplified by the eardrum and ossicles. Finally, the organ of Corti in the cochlea detects these noises and transmits them to the brain via nerve impulses.

The fluid in the cochlea vibrates as a result of pressure waves traveling from the stapes to the oval window. Depending on the sound frequency, these vibrations move the thin basilar membrane that is connected to the organ of corti, activating the hair cell receptors. Additionally, sound first passes through the auditory tube from the outer ear to the tympanic membrane or eardrum. However, the middle ear, not the inner ear, is where the ossicles are found not of the oval window, but transfer vibrations to the oval window.

The various tissues and structures that make up the ears aid in the processing of sound that is heard in the environment. Learn about the inner and outer ear, eardrum, eustachian tube, cochlea, and semicircular canals as well as how they work.

From the law of conservation of momentum, the first egg did not break because it forward momentum is transferred to the cloth while the second egg broke, the block exerts an opposite force equal to the momentum of the egg on the egg.

Momentum is the product of the mass of an object and its velocity of motion.

The law of conservation of momentum states that the momentum of an isolated system of colliding bodies is conserved.

When an egg is thrown on a large sheet of cloth suspended, the egg does not break because the momentum of the egg is transferred to the cloth as it is depressed.

However, a second egg, thrown with similar force at a suspended concrete block, did break on impact because the block does not move forward, instead it exerts an equal but opposite force on the egg resulting in the egg breaking.

Therefore, from the law of conservation of momentum, the first egg did not break because it forward momentum is transferred to the cloth while the second egg broke, the block exerts an opposite force equal to the momentum of the egg on the egg.

The equivalent resistance in the given series circuit is 18 Ω.

Ohm's law, Which states that the current flowing through a conductor between two points is directly proportional to the voltage across the two points and inversely proportional to the resistance between them.

To calculate the equivalent resistance in a series circuit, we can simply add up the resistance of each component in the circuit. In the given series circuit with a 12 V battery, a current of 2 amps, and 3 light bulbs, each having the same resistance, the equivalent resistance can be calculated as follows:

R_eq = R_1 + R_2 + R_3

Since each light bulb has the same resistance, we can represent the equivalent resistance as:

R_eq = 3 × R

where R is the resistance of each light bulb.

To find the value of R, we need to use Ohm's law, which states that the voltage drop across a resistor is directly proportional to the resistance of the resistor and the current flowing through it. In the given circuit, the voltage drop across each light bulb is 12 V (the voltage of the battery), and the current flowing through each light bulb is 2 A. Therefore, we can calculate the resistance of each light bulb as follows:

R = V / I

R = 12 V / 2 A

R = 6 Ω

Substituting this value of R in the equation for equivalent resistance, we get:

R_eq = 3 × 6 Ω

R_eq = 18 Ω

Therefore, the equivalent resistance in the given series circuit is 18 Ω.

a) To find the linear acceleration of block A and block B in the Atwood's machine, we can use the equations of motion and torque. Since there is no slipping between the cord and the surface of the wheel, the angular acceleration of the wheel can be related to the linear accelerations of the blocks.

Let's assume that block A is moving downwards and block B is moving upwards. The net force on block A is the tension in the left side of the cord (T_left) minus the weight of block A (m_A * g), and the net force on block B is the tension in the right side of the cord (T_right) minus the weight of block B (m_B * g). We can set up the equations of motion for both blocks:

For block A:

m_A * a_A = T_left - m_A * g      (1)

For block B:

m_B * a_B = T_right - m_B * g    (2)

The torque equation for the wheel is given by:

I * α = (T_right - T_left) * r     (3)

Where I is the moment of inertia of the wheel, α is the angular acceleration of the wheel, and r is the radius of the wheel.

Since there is no slipping, the linear acceleration of both blocks is equal to the acceleration of the wheel, which can be expressed as r * α. Substituting this into equations (1) and (2), and substituting the expression for α in equation (3), we can solve for the linear accelerations:

For block A:

m_A * a_A = T_left - m_A * g

a_A = (T_left - m_A * g) / m_A     (4)

For block B:

m_B * a_B = T_right - m_B * g

a_B = (T_right - m_B * g) / m_B   (5)

From equation (3):

I * (a_A / r) = (T_right - T_left) * r

T_right - T_left = (I * a_A) / r^2   (6)

b) To find the tension in the right side of the cord (T_right), we can use equation (6) derived above. Rearranging the equation, we have:

T_right = T_left + (I * a_A) / r^2    (7)

Substitute the values of T_left, I, a_A, and r into equation (7) to calculate the tension in the right side of the cord.

c) Similarly, to find the tension in the left side of the cord (T_left), we can use equation (6) derived above. Rearranging the equation, we have:

T_left = T_right - (I * a_A) / r^2    (8)

Substitute the values of T_right, I, a_A, and r into equation (8) to calculate the tension in the left side of the cord.

Answer:

The ideal temperature of catalase activity is 66.6 degrees Celsius, so a temperature between 60 degrees and 70 degrees should most likely release the most oxygen during the reaction.

Explanation:

The velocity of the body will be 30.6 m/s.

The object's highest vertical point during its trajectory is at its maximum height. Before it reaches the highest point, the item is flying upward; once it reaches that point, it is falling.

The velocity of the body is 60 m/s when thrown vertically upwards.

The maximum height attained by the body after 3 seconds.

Then, the initial velocity of the body is :

u = 60 m/s

t = 3 seconds

Then, using the equation of motion:

v = u - gt , the negative sign indicates that the body is moving opposite to gravity.

Therefore,

v = 60 - (9.8)(3)

v = 60 - 29.4

v = 30.6 m/s

Hence, the final velocity of the body when thrown upwards before it comes to stop is 30.6 m/s.

To find the distance from the surface of the sphere where there is a force of 8.3 × 10−6 N on a charge, we can use Coulomb's Law:
F = kq₁q₂/r²
Where F is the force, k is Coulomb's constant (9.0 × 10⁹ N·m²/C²), q₁ and q₂ are the charges, and r is the distance between the charges.
The distance from the surface of the sphere where there is a force of 8.3 × 10⁻⁶ N on a charge q is 3.75 × 10⁷ m √(q).

We can rearrange the equation to solve for r:
r = √(kq₁q₂/F)
Plugging in the given values:
r = √((9.0 × 10⁹ N·m²/C²)(-13 × 10⁹ C)(q)/(8.3 × 10⁻⁶ N))
r = √((9.0 × 10⁹ N·m²/C²)(-13 × 10⁹ C)(q)/(8.3 × 10⁻⁶ N))
r = √((-1.17 × 10¹⁴ N·m²/C)(q)/(8.3 × 10⁻⁶ N))
r = √((-1.17 × 10¹⁴ N·m²/C)(q)/(8.3 × 10⁻⁶ N))
r = √((-1.17 × 10¹⁴ N·m²/C)(q)/(8.3 × 10⁻⁶ N))
r = √((-1.41 × 10²⁰ N·m²/C²)(q))

Answer:

Explanation:

The force between two masses separated by a distance r is given as:

\(F=G\frac{m_1m_2}{r^2}\)

Where F is the attractive force between 2 masses, m1 and m2, r is the distance between the centres of the masses and G is the universal gravitation constant, which is \(6.674*10^-11 Nm^2/kg^2\)

The mass of the earth (\(m_1\)) is far greater than the mass of the sputnik (\(m_2\)). Therefore \(m_1m_2=m_1\). The mass of the sputnik is neglected, therefore:

\(F=G\frac{m_1}{r^2}=\frac{(6.674*10^{-11})(5.98*10^{24})}{(6.96*10^6)^2} = 8.2389N\)

But F is actually centripetal acceleration, a = v²/r

\(8.2389 = v^2 / 6.96*10^6\\v=7572m/s\)

The eye and a camera share similarities in the way they capture images. However, they also differ in several ways such as the eye is capable of adjusting to different lighting conditions and focusing on objects at different distances, whereas a camera requires manual adjustments to achieve the same effects.

The iris in the eye corresponds to the aperture in a camera. The aperture controls the amount of light that enters the camera, just as the iris controls the amount of light that enters the eye. Both the iris and aperture can be adjusted to let in more or less light depending on the situation.

The retina in the eye corresponds to the image sensor in a camera. The retina converts the light that enters the eye into electrical signals that are sent to the brain, allowing us to see. Similarly, the image sensor in a camera converts the light that enters the camera into digital signals that are stored on memory cards.

The cornea in the eye corresponds to the camera lens. The cornea helps to focus light onto the retina, just as the lens of a camera helps to focus light onto the image sensor. Both the cornea and the camera lens can be adjusted to change the focus of the image.

Overall, while there are similarities between the eye and a camera, there are also several differences in the way they function.

The maximum current passing through the pump is approximately 11 amperes.

To find the maximum instantaneous power dissipated by a 2.5-hp pump connected to a 240-Vrms AC power source, follow these steps:

1. Convert the horsepower (hp) to watts (W): 1 hp is equal to 746 watts, so 2.5 hp × 746 W/hp = 1865 W.

2. Determine the maximum power: For an AC power source, the maximum power is √2 times the RMS power. So, the maximum power = 1865 W × √2 ≈ 2637.4 W.

The maximum instantaneous power dissipated by the pump is approximately 2637.4 watts.

To find the maximum current passing through the pump:

1. Use the formula: Power (P) = Voltage (V) × Current (I).

2. Rearrange the formula to solve for current: I = P / V.

Bullying in the schools has negative effects on individual students and on the school climate as a whole. Bullying can cause long-term problems for both the victims of bullying and the bullies themselves. To explore the effects of bullying on adolescents, we will define bullying, identify the characteristics of bullies and victims, outline the extent and consequences of bullying, and present resources for further information and assistance.

Bullying is any behavior that is initiated by one or more students against a victim or victims that causes physical or psychological intimidation. Bullying behaviors can be classified as either direct (such as teasing, threatening, hitting, or stealing) or indirect (such as rumor spreading or social isolation). Boys typically employed direct methods of bullying, while girls tend to use in direct methods. Either way, behaviors must occur repeatedly overtime to be classified as bullying.

Characteristics of Bullies and Victims

There are specific behaviors that bullies tend to exhibit. The bullies often need to feel powerful and in control. They may feel no remorse when they inflict injury and suffering on others. Bullies tend to defy authority and are likely to break school rules. They seem to have little anxiety and appear to possess high self-esteem. Students who come from homes characterized by physical punishment tend to be more likely to exhibit these types of behaviors.

Victims also tend to exhibit specific characteristics. They are often anxious, insecure, cautious, and have low self-esteem. Victims tend to be socially isolated, and may lack social skills and friends. Because they tend to be weaker than their peers, either physically or socially, victims rarely retaliate against bullies. Students who have close ties with their parents/guardians or who have overprotective parents/guardians are more likely to be victimized by bullies.

Other given choices are not related to the given scenario. So that Option A seems to be the right answer.

Using the equation of motion:

1/2mv^2 = 1/2kx^2

where

m is the mass of the block,

v is the velocity

x is the displacement from the equilibrium position

we can find the initial displacement, d.

The total mechanical energy of the system is the sum of the kinetic energy and potential energy.

Initial Potential energy = 1/2kd^2

Final kinetic energy = 1/2mv^2

so,

v=sqrt(2*(1/2kd^2))/m

Work done = change in kinetic energy

The work done by friction is equal to the force of friction multiplied by the distance over which the force acts.

Friction force = friction coefficient * normal force

Friction force = friction coefficient * m * g

work done = friction force * distance

By putting the value of friction force and work done we can find the coefficient of kinetic friction.

Hooke's Law states that the force (F) required to extend or compress a spring by some distance x is proportional to that distance.
