Answer:
in the ball
Explanation:
potential energy is where an object has energy, always, but it isn't always moving, and when you drop the ball, it has kinetic energy.
Answer:
1) H. magnitude, 2) D. coordinates, 3) G. distance.
Explanation:
1) A vector has, by definition, both <em>magnitude</em> and direction. (Reason: Scalars have only magnitude)
2) Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as <em>coordinates</em>. (Reason: Coordinates are ordered pairs)
3) Speed differs from velocity in the same way that <em>distance</em> differs from displacement. (Reason: The distance is the magnitude of displacement)
Answer:
Wilhelm Roentgen, Professor of Physics in Worzbury, Bavaria, was the first person to discover the possibility of using electromagnetic radiation of create what we now know as the x-ray
Answer:c>a>b
Explanation:
Given
All the engine extracts same amount of heat(Q) from High-temperature reservoir
For a) 400 and 500 K
For b)500 K and 600K
For c) 400 K and 600 K
So c will give the highest amount of work
c>a>b
Answer:
if somthing is warm or if somthing moves it usally has energy
