The main purpose of the turbine in the turbojet engine is to "<span>compress the air". There is also the added factor of pushing the air, which increases mobility. </span>
Answer:
Energy, potential energy, is stored in the covalent bonds holding atoms together in the form of molecules. This is often called chemical energy
Answer:
The magnitude of the impulse experienced by the particle is 100 kg.m/s.
Explanation:
Given;
mass of the particle, m = 5 kg
initial velocity of the particle, v₁ = 10 m/s
assuming the particle rebounds with same velocity backwards, v₂ = - 10 m/s
The impulse experienced by the particle is the change in linear momentum;
J = ΔP = mv₁ - mv₂
J = m(v₁ - v₂)
J = 5 (10 - (-10))
J = 5 (10 + 10)
J = 5(20)
J = 100 kg.m/s
Therefore, the magnitude of the impulse experienced by the particle is 100 kg.m/s.
Answer:
Correct answer: D = 10,800 m = 1.08 · 10⁴ m
Explanation:
None of the answers offered are correct.
The described motion is uniform with constant speed and the formula is:
D = v · t
Given: v = 15 m/s and time t = 12 min = 12 · 60 seconds = 720 seconds
D = 15 · 720 = 10,800 m = 1.08 · 10⁴ m
D = 10,800 m = 1.08 · 10⁴ m
