Answer:
Gravity controls the movement of the planets around the sun, holds together stars grouped in galaxies, and galaxies grouped in clusters. The Universal Law of Gravitation depends on two things. First it depends on mass of each object and the second factor is the distance between two objects. If the mass of one object is Larger, the gravitational pull towards it will be larger and the smaller distance, the larger the gravitational pull will be between the objects. Therefore the Larger planets have more moon and the inner planets have less.

Answer:
we need to know what the choices are?
Explanation:
Two acetate rods, both charged with silk would repel because they are both have positively charged electrons.
Explanation: Opposite charges attract. Like charges repel.
Explanation:
The question is incomplete. To get the voltage V across the resistors, we need to total current flowing in the circuit.
Let the current I = 6 A
According to ohms law, V = IRt
V is the total voltage
I is the total current
Rr is the total effective resistance
Since the 2 4ohms resistors are connected in parallel;
1/Rt = 1/4 + 1/4
1/Rt = 2/4
Cross multiply
2Rt = 4
Rt = 4/2
Rt = 2 ohms
Get the voltage V.
V = IRt
V = 6(2)
V = 12V
Hence the required voltage will be 12V
<em>Note that the value of the current used was assumed. The same calculation can be employed for any value of the current</em>
Answer:
<u>198785.714286 Joules</u>
Explanation:


<u>To find work:</u>
Now that the force and the distance are known, plug and chug:

Note that the question is asking for the magnitude of work, so the negative can be discarded as it is a directional component.
So, your answer is
<u>198785.714286 Joules</u>
