If the distance between two objects is increased by a factor of 3 (tripled), how will this affect Fg?

Physics

Answer:

2. F g decreases to 1/9

Explanation:

The formula for calculating the Force of gravity between two masses separated by a distance is expressed as;

F = GMm/d² ... 1

If the distance is tripled, the new force will be;

F1 = GMm/(3d)²

F1 = GMm/9d² ... 2

Divide equation 1 by 2

F/F1 = GMm/d²÷GMm/9d²

F/F1 = GMm/d²×9d²/GMm

F/F1 = 1 * 9

F = 9F1

F1 = 1/9 F

<em>This means that the new force decreases to 1/9</em>

a mass on a spring vibrates in simple harmonic motion at an amplitude of 8.0 cm. if the mass of the object is 0.20kg and the spr
Reil [10]

Answer:

4.06 Hz

Explanation:

For simple harmonic motion, frequency is given by

f=\frac {1}{2\pi}\times \sqrt{\frac {k}{m}} where k is spring constant and m is the mass of the object.

Substituting 0.2 Kg for mass and 130 N/m for k then

f=\frac {1}{2\pi}\times \sqrt{\frac {130}{0.2}}=4.057670803\\f\approx 4.06 Hz

A 60-W light bulb radiates electromagnetic waves uniformly in all directions. At a distance of 1.0 m from the bulb, the light in
krek1111 [17]
1. If we increase the distance to twice it's original value, the light intensity is reduced by one-fourth, the light intensity would be:
I0/4

2. rms magnetic field is inversely proportional to distance, so the new rms magnetic field would be:
B0/2

3. average energy density is inversely proportional to the square of the distance, so the new average energy density is:
E0/4

Each of the following would cause an increase in blood pressure except __________.
kicyunya [14]

Answer:

an inhibitor of angiotensin II

Explanation:

Angiotensin, specifically angiotensin II binds to many receptors in the body to affect several systems. It can normally increase blood pressure by constricting the blood vessels but with the introduction of an inhibitor, it wouldn't bring about an increase in blood pressure.

Two pucks collide with each other. after the collision they do not stick together. is kinetic energy conserved in the collision?
miv72 [106K]
Since they do not stick after collision hence collision is elastic. In elastic collision, both momentum and kinetic energy is conserved because in this type of collision, first body deforms but then quickly regains its former shape and transfers its kinetic energy to the second pluck.
So kinetic energy is conserved.

The force that pushes charges through a wire is called _____.
zhenek [66]

The force that pushes charges through a wire is called voltage. Electric current is the movement of the electrons caused by potential difference. For example, in a circuit, the electrons in the bulb will not move without the potential difference or voltage. When there is voltage, electric current occurs because there is a driving force for the electrons in the wire to move.
