Answer:
<em>2.753*10^-11N</em>
Explanation:
According to Newton's law of gravitation, the force between the masses is expressed as;
F = GMm/d²
M and m are the distances
d is the distance between the masses
Given
M = 3.71 x 10 kg
m = 1.88 x 10^4 kg
d = 1300m
G = 6.67 x 10-11 Nm²/kg
Substitute into the formula
F = 6.67 x 10-11* (3.71 x 10)*(1.88 x 10^4)/1300²
F = 46.52*10^(-6)/1.69 * 10^6
F = 27.53 * 10^{-6-6}
F = 27.53*10^{-12}
F = 2.753*10^-11
<em>Hence the gravitational force between the asteroid is 2.753*10^-11N</em>

To solve this problem we will apply the concepts related to Ohm's law and Electric Power. By Ohm's law we know that resistance is equivalent to,
![R_{eq}= \frac{V}{I}](https://tex.z-dn.net/?f=R_%7Beq%7D%3D%20%5Cfrac%7BV%7D%7BI%7D)
Here,
V = Voltage
I = Current
While the power is equivalent to the product between the current and the voltage, thus solving for the current we have,
![P=VI \rightarrow I = \frac{P}{V}](https://tex.z-dn.net/?f=P%3DVI%20%5Crightarrow%20I%20%3D%20%5Cfrac%7BP%7D%7BV%7D)
![I =0.608 A](https://tex.z-dn.net/?f=I%20%3D0.608%20A)
Applying Ohm's law
![R_{eq} = \frac{120V}{0.608A}](https://tex.z-dn.net/?f=R_%7Beq%7D%20%3D%20%5Cfrac%7B120V%7D%7B0.608A%7D)
![R_{eq} = 197.4\Omega](https://tex.z-dn.net/?f=R_%7Beq%7D%20%3D%20197.4%5COmega)
Therefore the equivalent resistance of the light string is ![197.4\Omega](https://tex.z-dn.net/?f=197.4%5COmega)
The correct answer is the following.
The forces that act on the piano are: 2) gravitational force acting on the piano (piano's weight). 5) force of the floor on the piano (normal force). 7) force of Chadwick on the piano.
As we see in the picture that I have attached is Chadwick pushing the piano in a horizontal plane. So Chadwick is applying a force that produces an acceleration. It is his force on the piano plus the acceleration of the weight of the piano, it's a gravitational force. This is pure physics applied to an object.
Supernova nucleosynthesis is also thought to be responsible for the creation of rarerelements heavier than iron<span> and nickel, in the last few seconds of a type II supernova event.</span>
