Answer:
Explanation:
Impulse of a force is measured by force x time or F X t
Impulse also equals change in momentum or
F x t = m v₂ - m v₁
The given case is as follows
in the first case
F x t = mv - o = mv
F = mv / t
in the second case
F₁ x 4 t = mv
F₁ = 1/4 x mv /t
F₁ = F / 4
option a) is correct .
iii )
In the last case
F₂ X t = m v/2 -0
F₂ = 1/2 x mv / t
= 1/2 x F
F₂ = F/2
Option e ) is correct.

Answer:
Considerando, que al tope de la atmósfera llega un 100% de la radiación solar, de este total, sólo un 25% llega directamente a la superficie de la Tierra y un 25% es dispersado por la atmósfera como radiación difusa hacia la superficie, esto hace que cerca de un 50% de la radiación total incidente llegue a la ...
