Which sentence from paragraph 4 most precisely explain the factors that determine the force of gravity?

" In other words, these equations states the gravitational force between two bodies is proportional to the product of their masses and inversely proportional to the square of the distance between them."

It's formula is g=GM/r²

Force F acts between two charges, q1 and q2, separated by a distance d. If q1 is increased to twice its original value and the d

Step2247 [10]

Okay, haven't done physics in years, let's see if I remember this.

So Coulomb's Law states that $F = k \frac{Q_1Q_2}{d^2}$ so if we double the charge on $Q_1$ and double the distance to $(2d)$ we plug these into the equation to find

 $F_{new} = k \frac{2Q_1Q_2}{(2d)^2}=k \frac{2Q_1Q_2}{4d^2} = \frac{2}{4} \cdot k \frac{Q_1Q_2}{d^2} = \frac{1}{2} \cdot F_{old}$ 

So we see the new force is exactly 1/2 of the old force so your answer should be $\frac{1}{2}F$ if I can remember my physics correctly.

What type of wave is produced when the frequency of a visible light wave is increased

SIZIF [17.4K]

-- If the frequency of a wave is too high for our eyes to detect it ... but not too too high ... we call it an ultraviolet wave.

-- If the wave's frequency is even higher than that, we call it an X-ray wave.

-- If the wave's frequency is even higher than that, we call it a Gamma Ray wave.

Higher Current = ________ Moving Electric Charges (Electrons) *

Eva8 [605]

Answer:

Higher current is normally achieved by faster moving electrons.

Explanation:

Current is solely not the speed of the electric charges, but speed of the electrons is one of the factors that current depends on.

Current is the net charge flowing per unit time.

Current can be represented by:

I=v×e×N×A

where,

I= current

e= electric charge

v= speed of electrons

N=no. of free electric charges per volume

The unit of current is Ampere, represented by A. It is flow of 1 coulomb of charge in 1 second.
