Answer:
3.125J
Explanation:
K.E.= 1/2(mass)(velocity)^2
K.E.=1/2(0.25)(5)^2=3.125
Answer:
0.85 c
Explanation:
When the two travel at right angles to each other , their relative velocity is given by the hypotenuse formed by the x and y direction velocities.
Relative velocity of the two protons is given as

If v = 3/5 c , then the relative speed =
(3/5c) =0.85 c
An ecosystem is the diversity of many communities of organisms where they interact with living as well as non living thing whereas community contains the variety of populations of different species. Hope this helps x
