they will choose the path that has not resistance
Answer:
<h2>468,750 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula
m is the mass
v is the velocity
From the question we have
We have the final answer as
<h3>468,750 J</h3>
Hope this helps you
<u>False, </u>

A build up of positive charge builds up on the ground under the cloud, attracted to the negative charge in the cloud. The earth's positive charge concentrates to anything that sticks up - trees, lightning conductors,

1. Most PE, because PE is directly proportional to distance (height)
Height: 100 meters
Speed: 0 mph
2. Most KE, because KE is directly proportional to speed
Height: 10 meters
Speed: 40 mph
3. Most TE, average KE
Height: 10 meters
Speed: 40 mph
4. The skater gains thermal energy as she goes down the slope, because the speed of the skater increases, so it increases the total kinetic energy of the particles, and makes them vibrate faster, resulting in a higher temperature.
