Answer:
A hypothesis is what you think will happen.
A conclusion is the results of an experiment summarized.
Hope this helps.
Answer:
So, if the sphere has net amount of charge on it, such that the test charge will experience its intensity in the given region of influence. As, the charge particles size plays a very important role in this regards, as the total distribution of the net charge occurs on the surface of the sphere.
So, we have the following formula in order to make the calculations and have the results, which is as follows:
- E=F/q, (while "F" is the net amount of force applied by the charged body when the test charge,q is placed in its field)
- And if we analyze the Gauss's law we have, Ф=q/∈,
- While, we can obtain the required results by putting all the data into the following equation,as follows:
- E=kq/r².
Complete these sentences. If a roller coaster train has a potential energy of 1,500 J and a kinetic energy of 500 J as it starts to travel downhill, its total energy is J. Once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 J, and its potential energy decreases to J. When the train reaches the bottom of the track and is traveling along the ground, its kinetic energy is J.
The answer is: 2000 J for the first sentence, 900 for the second sentence, and 2,000 for the last one
