Deposition:
- when a gas changes directly to a solid
- latent heat is released
- physical change, NOT a chemical change
There's only one question there.
The answer is "Greater amplitude".
1. its must be B and 2. must be C
Answer:
V = 0.0806 m/s
Explanation:
given data
mass quarterback = 80 kg
mass football = 0.43 kg
velocity = 15 m/s
solution
we consider here momentum conservation is in horizontal direction.
so that here no initial momentum of the quarterback
so that final momentum of the system will be 0
so we can say
M(quarterback) × V = m(football) × v (football) ........................1
put here value we get
80 × V = 0.43 × 15
V = 0.0806 m/s
