Answer:
The correct answer would be B.
Explanation:
I believe the answer is B because for electrical energy you would need electric charges to be moved by kinetic energy.
Answer: A, a polished pale yellow surface would likely be the best reflector of heat energy.
The leading theory of the driving force behind tectonic plate motion envisaged large scale convection current in the upper mantle, which can be transmitted throug the asthenosphere.
Answer:
m1 = 20g (= 0.02 kg)
Mass of pistol, m2 = 2 kg
Initial velocity of the bullet (u1) and pistol (u2) = 0
Final velocity of the bullet, v1 = +150m s-1
Let v be the recoil velocity of the pistol.
Total momentum of the pistol and bullet after it is fired is
= (0.02 kg x 150 m s-1) + (2 kg x v m s-1)
= (3 + 2v) kg m s-1
Total momentum after the fire = Total momentum before the fire
3 + 2v = 0
→v = -1.5 m/s
