According to the law of gravitational force:
the force between any two objects is directly proportional to the masses of the objects and inversely proportional to the square of the distance between these two objects.
Based on this:
if a 9 c charge is replaced with a 4 c charge while the distance between the charges is kept constant:
18/9 = F/4
2 = F/4
F = 2 x 4 = 8
Answer:
Explanation:
Let density of water be ρ .
During flow , volume of water flowing per second is constant
loss of P. E per unit volume = ρ gh , 83.5 % is lost
Gain of K E per unit volume = 1/2 ρ v²
83.5 % of mgh = ρ 1/2 ρ v²
1/2 ρ v² = .835 x 9.8
v² = 2 x .835 x 9.8
= 16.366
v = 4.04 m /s
Explanation:
let's take the volume of each first:
ice cream: 10×10×4=400cm^3
freezer: 40×40×20=32,000cm^3
now we just divide: 32000/400=80
