A. electrical energy is transformed into mechanical energy.
Answer:
5m
Explanation:

Use the Pythagorean theorem to calculate the long edge of the triangle, which would be his displacement.
Your answer would be D.
If an object has mass, it has gravity, and the more mass it has, the stronger its gravity. During the formation of planets, essentially, various matter and elements pulled and fused together (because of the gravity), forming planetesimals.
Answer:
I think it is <em><u>Rooting</u></em><em> </em><u><em>Reflex</em></u>
Density = Mass/Volume
So, given mass = 20 g and volume = 40 cm^3
By substituting in above equation, Density = 20/40 = 0.5 g/cm^3
Hope it helps.
