if the separation between two masses is doubled, does the gravitational force between them increase or decrease? By what factor?

Answers

Answer 1

Answer:

When the separation between two masses is doubled, the gravitational force between them decreases by 4.

What is meant by gravitational force ?

Gravitational force is defined as the force of attraction experienced by a body due to the gravity of earth.

Here,

The separation between two masses is doubled.

That means the distance, r₂ = 2r₁

We know that the equation of gravitational force is given by,

F = GMm/r²

where G is the gravitational constant

From the equation, we know that the gravitational force obeys the inverse square law.

That means the gravitational force is inversely proportional to the square of the distance between the masses.

So, F $\alpha$ 1/r²

Therefore,

F₂/F₁ = (r₁/r₂)²

F₂ = F₁(1/2)²

F₂ = F₁/4

Hence,

When the separation between two masses is doubled, the gravitational force between them decreases by 4.

Answer 2

Answer:

increase by a factor of 4.

Explanation:

If the separation distance between two objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).

A transverse wave has an amplitude of 2.4m. What is the vertical distance, in meters, between the top of a Crest and the bottom of a Trough?

Answers

Answer:

4.8 m

Explanation:

A transverse wave is a wave in which the oscillation of the particles occur in a direction perpendicular to the direction of motion of the wave.

The amplitude of a transverse wave is the maximum displacement of the wave with respect to the equilibrium position.

The crest of a wave is the position of maximum displacement on the positive side, while the trough of a wave is the position of maximum displacement on the negative side.

This means that the amplitude of a wave is equal to the distance between a crest (or a trough) and the equilibrium position.

Therefore, we have:

$d=2A$

where:

d is the distance between the top of a crest and the bottom of a trough

A is the amplitude of the wave

Here we have:

A = 2.4 m

So, we find

$d=2\cdot 2.4 = 4.8 m$

Hi there!

The spacecraft widely known for it's beautiful images of the gas giants and its moons is the Voyager spacecraft (Voyager 1 & 2). The Voyagers took advantage of a rare opportunity in which all the gas giant planets were aligned that allowed them to get a gravity assist from each planet allowing for extremely close pictures and extremely high speeds on the spacecraft.

Explain the flow of electrons from the battery through the circuit

Answers

Answer:

Electrons are negatively charged, and so are attracted to the positive end of a battery and repelled by the negative end. So when the battery is hooked up to something that lets the electrons flow through it, they flow from negative to positive.
