Answer:
(a) Power= 207.97 kW
(b) Range= 5768.6 meter
Explanation:
Given,
Mass of bullet,
Kinetic energy imparted,
Length of rifle barrel,
(a)
Let the speed of bullet when it leaves the barrel is .
Kinetic energy,
Initial speed of bullet,
The average speed in the barrel,
Time taken by bullet to cross the barrel,
Power,
(b)
In projectile motion,
Maximum height,
Range,
given that,
then,
Answer:
1. In my opinion I think water evaporation is like the law of conservation, because water changes form to vapor then comes back to Earth as rains have simply changes form in the cycle.
2. Well, a humorous conservation law… whenever a certain that energy changes form it turns into a food item. So then if you're ever stranded on an island without food all you have to do is convert enough energy and just like that you have burgers and French fries.

hope this helps! :) just did this assignment lol
By using an electric field, it is feasible to differentiate between these different forms of radiation.
<h3>What is a radioactive source?</h3>
A source that emits radiation like gamma, beta, and alpha rays is said to be radioactive. Using an electric field, we can discriminate between these different forms of radiation.
The field does not deflate the gamma rays, but it does deflate the alpha and beta rays, with the alpha being deflated to the field's negative portion and the beta to its positive part.
Hence, by using an electric field, it is feasible to differentiate between these different forms of radiation.

The answer should be ''Decrease'' to fill in the blank because squirrels usually live in trees and get food from there so without a place to live when its raining and no food to survive, than they would die and lessen their population so that's why decrease is the answer.
