Rocket fuel will and smoke will emit from the thrusters.
The answer is a Viscosity because it describes the internal friction of a moving liquid
Answer:
a burning piece of converts Chemical energy into Heat(Thermal) and Light energy
Answer:
The correct answer is option a.
Explanation:
Conservation of momentum :

Where :
= masses of object collided
= initial velocity before collision
= final velocity after collision
We have :
Two equal-mass carts roll towards each other.

Initial velocity of 
Initial velocity of
(opposite direction)
Final velocity of
(same direction )
Final velocity of
(same direction)


v = 0.5 m/s
rg135
The speed of the carts after their collision is 0.5 m/s.
