Explanation:
1. draught
2. Parallax error
3. angle if displacement
4. air resistance or any form of obstruction
Answer:
c
Explanation:
because whatever elements are used like gas uses water evaporation so yeah
Acceleration = change in velocity/time
= 40/5
=8m/s^2
Answer:
0.37 m/s to the left
Explanation:
Momentum is conserved. Initial momentum = final momentum.
m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂
Initially, both the fisherman/boat and the package are at rest.
0 = m₁ v₁ + m₂ v₂
Plugging in values and solving:
0 = (82 kg + 112 kg) v + (15 kg) (4.8 m/s)
v = -0.37 m/s
The boat's velocity is 0.37 m/s to the left.
