Answer:
Explanation:
As we know that box was initially at rest
so here work done by all forces on the box = change in its kinetic energy
so we will have
now we have
m = 10 kg
L = 3.5 m
so we will have
so final speed is given as
Answer:
Explanation:
m = ρV = 1.03( 1000 kg/m³)(π(2² m²)(3.0 m)) = 12360π kg
m ≈ 38,830 kg
Answer:
Explanation:
P = Power Output = 1000 W
r = Radius = 35000000 m
= Permittivity of free space =
c = Speed of light =
