When bouncing a ball, the bouncing motion results in the ball ____________.
yan [13]

Answer:

B) changing position

Explanation:

When a ball bounces to the ground it hits the ground with some energy. The amount of energy with which it hits the ground is kinetic energy. When it comes in the contact with the ground kinetic energy gets converted into potential energy. This potential energy again gets converted into kinetic energy and balls moves again from the ground and bounces multiple times. So, due to multiple bounce the position of the ball changes.

Thus, When bouncing a ball, the bouncing motion results in the ball changing position.

What are the change in internal energy if 250 j of hear is added to a system of 80 j of work is done by the system
Sphinxa [80]

Answer:

Explanation:

dU= dq+w

dU is change in internal energy of the system

dq is the amount heat added or released by the system which be positive or negative respectivelý

And w is the amount of work done by the system or on the system which will be positive or negative respectively.

Hence,

dU= 250+80= 330 J

The change will be positive

Out of solid and liquid which has more effect on gravitation​
il63 [147K]

Answer:

The effect of gravitation is more in liquid than on solid because inter molecular force of attraction is less in liquid and it is weak than that of solid. ... Whereas in solid the molecule are densely packed together an the inter molecular forces are constantly acting upon one another, this results in higher forces.

A 57-gram tennis ball moving at 70 miles per hour is hit with a 110-gram tennis racquet moving at 60 miles per hour. Which state
Whitepunk [10]

Answer:

D. Because mass and energy are both conserved, the total amounts of mass and energy are the same before and after impact.

Explanation:

As we know that, the energy in motion is Kinetic Energy mathematically given as:

KE=\frac{1}{2} m.v^2

<u>Now, according to the law of conservation of energy:</u>

\frac{1}{2} m_1.u_1^2+\frac{1}{2} m_2.u_2^2=\frac{1}{2} m_1.v_1^2+\frac{1}{2} m_2.v_2^2

where:

m_1\ \&\ m_2 mass of racquet and ball respectively and u_1\ \&\ u_2 are their respective initial velocities.

v_1\ \&\ v_2 are the respective final velocities.

<u>Also the law of conservation of momentum is applicable in this case:</u>

m_1.u_1+ m_2.u_2= m_1.v_1+m_2.v_2

In this case the velocity of the lighter mass will get increases in the final condition.
