Explanation:
W.D. = F * s = 50N * 2m = 100J.
The air pushes the engine with an equal force in the opposite direction.
Whenever force is used there is an opposite yet equal affect.
Answer:
98.33 %
Explanation:
On an elliptical orbit, angular momentum will be conserved .
Angular momentum = I ω = mvR
So mv₁R₁ = mv₂R₂
= v₁R₁ = v₂R₂
where v₁ is velocity and R₁ radius in low orbit (perigee)and v₂ and R₂ is velocity and radius in high orbit ( apogee ).
Here R₁ = Radius of the earth , R₂ is distance between moon and earth.
R₁ / R₂ = 1/60
v₁ /v₂ = R₂ / R₁ = 60
v₂ / v₁ = 1 / 60
1 - (v₂ / v₁ ) = 1 -( 1 / 60)
(v₁ -v₂)/v₁ = ( 60-1 )/60
(v₁ -v₂)/v₁ x 100 = 5900/60 = 98.33 %
