The answer would be a=5 m/s^2
I hope this helps you, have a great day!
The hardest part of the job is to find the right formula to use, and write it down. You've already done that ! The rest is just turning the crank until an answer falls out.
You wrote. E = m g h.
Beautiful.
Now divide each side by (g h), and you'll have the formula for mass:
m = E / (g h).
You know all the numbers on the right side. Just pluggum in, do the arithmetic, and you'll have the mass.
D
Using the kinetic energy 1/2mv^2 formula
5*10^5 is the answer
<span>D) Electromagnetic radiation travels in the form of longitudinal waves.</span>
the answer is A it is so easy question
