Explanation:
Heat and temperature are related to each other, but are different concepts. Heat is the total energy of molecular motion in a substance while temperature is a measure of the average energy of molecular motion in a substance. ... Temperature does not depend on the size or type of object
Answer:
At the end of the handle farthest from the head of the hammer.
Explanation:
The force of the hammer is greatest the longer the radius is on a which would be the length of the handle. Simple mechanical advantage.
Answer:
<em>J=600 kg m/s
</em>
Explanation:
<u>Impulse And Momentum
</u>
Suppose a particle is moving at a certain speed 
and changes it to 
. The impulse J is equivalent to the change of linear momentum. The momentum can be computed by
The initial and final momentums are given, respectively, by:
Thus, the change of momentum is
It's equal to the Impulse J
Our data is
