A ball is thrown toward the ground. The figure shows the direction of the ball before it reaches the ground and the direction of

Kruka [31]

According to the principle of conservation of momentum, the momentum of the bouncing ball changes.

Also, the ball bounces less than its original height because some energy is lost due to heat, friction and air resistance.

<h3>How is momentum conserved in the bounce of balls?</h3>

The principle of conservation of momentum states that for any collision occurring in an isolated system, momentum is conserved.

a. For a body such as a ball dropped from a height, the total momentum is conserved.

However, there is a change in momentum of the ball as some of its momentum is transferred to the earth.

b. When the ball a ball of mass M is released from a height H1, it bounces to a height H2, which is about 1/2 of H1.

The value of H2 is less than that of H1 because some of the energy is converted to heat energy due to friction and air resistance, thereby its energy is less than its original value.

Therefore, the momentum of the bouncing ball is changes. Also, the ball bounces less than its original height because some energy is lost due to heat, friction and air resistance.

In a charging process, 1 × 10^13 electrons are removed from one small metal sphere and placed on a second identical sphere. Init

liraira [26]

Answer:

r = 0.303m

= 30.3cm

Explanation:

Given that,

The number of electrons transferred from one sphere to the other,

n = 1 ×10 ¹³e le c t r o n s

The electrostatic potential energy between the spheres,

U = − 0.061 J

The charge on an electron,

q = − 1.6 × 10 ⁻¹⁹C

The coulomb constant,

K = 8.98755 × 10 ⁹ N ⋅ m ² / C 2²

Due to the transfer of electrons, both spheres become equally and oppositely.

The charge gained by the sphere due to the excess of the electron is:

q ₁ = n q

= 1 ×10 ¹³ * − 1.6 × 10 ⁻¹⁹

= -1.6 × 10⁻⁶C

The charge left on the first sphere is =

q ₂ = -q₁ = 1.6 × 10⁻⁶C

The electric potential energy between two point charges is given by the following equation:

U = K q ₁q ₂/r

q ₁ and q ₂ are the two charges.

r is the distance between the charge and the point.

K = 8.98755 × 10 ⁹ N ⋅ m ² / C ²

we have:

-0.061 = (8.98755 × 10 ⁹ * (-1.6 × 10⁻⁶)²) / r

r = (18.41 × 10 ⁻³) / 0.061

r = 0.303m

= 30.3cm

A small metal ball is given a negative charge, then brought near to end a of the rod (figure 1). What happens to end a of the ro

erma4kov [3.2K]

What happens to end a of the rod when the ball approaches it closely this first time is; It is strongly attracted.

<h3>Electrostatics</h3>

I have attached the image of the rod.

We are told that the ball is much closer to the end of the rod than the length of the rod. Thus, if we point down the rod several times, the distance of approach will experience no electric field and as such the charge on end point A of the rod must be comparable in magnitude to the charge on the ball.

This means that their fields will cancel.

Finally, we can conclude that when a charge is brought close to a conductor, the opposite charges will all navigate to the point that is closest to the charge and as a result, a strong attraction will be created.

This also applies to a strong conducting rod and therefore it is strongly attracted.
