As the distance between two objects increases,what happens to the gravitational force

Physics
1 answer:
Vladimir [108]3 years ago
3 0

As the radial distance between two objects increases, the gravitational force which pulls the two towards each other decreases following the inverse square law. This is based on Newton's Law of Universal Gravitation, which as an equation states F_{g} = \frac{Gm_{1}m_{2}}{r^2}. If the distance between the two is doubled, the force of gravity is only 1/4 as strong. If it is tripled, it is only 1/9 as strong, and so on.

Weightlessness is the condition where the body has zero gravity ( its acceleration is equal to the acceleration due to gravity )

In an electroplating process, copper (ionic charge +2e, atomic weight 63.6 g/mol) is deposited using a current of 10.0 A. What m
statuscvo [17]

Answer:

1.974 g

Explanation:

Electrochemical equivalent of copper, z = 0.000329 g/C

I = 10 A

t = 10 minutes = 10 x 60 = 600 seconds

By the use of Farady's law of electrolysis

m = z I t

m = 0.000329 x 10 x 600

m = 1.974 g

A proton is released from rest at the origin in a uniform electric field that is directed in the positive x direction with magni
Vika [28.1K]

Explanation:

It is given that,

Electric field, E=950\ N/C

We need to find the change in the electric potential energy of the proton-field system when the proton travels to x = 2.5 m

From the conservation of energy, the loss in potential energy is equal to the gain in kinetic energy and kinetic energy is is equal to the work done.

W=F\times x

W=q\times E\times x

W=1.6\times 10^{-19}\times 950\times 2.5

W=3.8\times 10^{-16}\ J

So, the change in electric potential energy of the proton field system is 3.8\times 10^{-16}\ J. Hence, this is the required solution.

Lexy throws a dart with an initial velocity of 25m/a at an angle of 60 degrees relative to the ground. What is the approximate v
butalik [34]
Initial velocity = 25 m/s, angle 60°

sin (60°) = opposed leg / hypothenuse = Vertical velocity / Initial velocity

=> Vertical velocity = initial velocity * sin (60°) = 25 m / s * 0.866 = 21.65 m/s
