Answer:
electricity
If a rod is charged it is because of the electrical force acting on it
Answer:
<h2>D</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question
mass = 2 kg
velocity/speed = 3 m/s
We have
momentum = 2 × 3 = 6
We have the final answer as
<h3>6 kg.m/s</h3>
Hope this helps you
Answer:
A
Explanation:
When friction slows a sliding block, <u>the kinetic energy of the block is transformed into internal energy
.</u>
<em>The frictional movement of two surfaces over one another leads to the conversion of some of their kinetic energies to another energy - heat or thermal energy. Hence, the temperatures of the objects are raised in the process. </em>
<u>Therefore, when a sliding block is slowed down due to friction, some of the kinetic energy of the block would be transformed into internal energy in the form of heat.</u>
The correct option is A.
Answer:
The velocity of the ball is 5 m/s to the left.
Explanation:
-25kg*m/s divided by 5 kg gives
speed of -5 m/s
The velocity of the ball is 5 m/s to the left.
