Answer:
Stop watch
Stop clock
Explanation:
Absolute time is time measured in definite periods such as minutes, days, and years. It can be measured uising stop watch or stop clock
Answer:
<h2>3000 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula

m is the mass in kg
v is the velocity in m/s
From the question
m = 60 kg
v = 10 m/s
We have

We have the final answer as
<h3>3000 J</h3>
Hope this helps you
This being a perfect collision means no energy is lost during the collision. Because this question asks for speed and not velocity, the speed will be the same because the final energy is the same. The speed after the collision would therefore be 1.27 m/s.
Answer:
No
Explanation:
When a substance changes its state , there will not be any change in the mass of substance . For example , if we change 100 grams of water (liquid) to ice(solid) , the mass of ice will be same i.e., 100 grams . This shows there is no change in the mass even if a substance changes its state.

Your question asks what the slope of a Position vs. Time graph represents.
Your answer would be Velocity.
The slope of a Position vs. Time graph would represent the velocity of the object.
If the slope is positive, then the object has a positive velocity ,in which it is going forward.
If the slope is negative, then the object has a negative velocity, which means that it's going the opposite direction, or backwards.
If the slope is at a "horizontal" position, this means that the object is stopped or isn't moving at all.
