Answer:
Described below
Explanation:
When you see a car behind you in the rear view mirror, it means that light rays travelling from the right hand side of the car driver behind are being reflected by the mirror to get to your eyes on the right side of the light rays from the drivers left hand side.
Answer:
V₂ = 1.5 m/s
Explanation:
given,
speed of the first piece = 6 m/s
speed of the third piece = 3 m/s
speed of the second fragment = ?
mass ratios = 1 : 4 : 2
fragment break fly off = 120°
α = β = γ = 120°
sin α = sin β = sin γ = 0.866
using lammi's theorem
A,B and C is momentum of the fragments
4 x V₂ = 2 x 3
V₂ = 1.5 m/s
1.25, if the field is 1 meter away. I think that that is correct.
Explanation:
Assuming constant density, the pressure at a depth h is:
P = Patm + ρgh
3 (1.013×10⁵ Pa) = 1.013×10⁵ Pa + (1025 kg/m³) (9.81 m/s²) h
h = 20.1 m
