i think it's (C) They have different units ....
Answer:
The objects have opposite charges.
Explanation:
The object when released are moving towards each other simply because they attract each other.
- According to coulombs law of charges, like charges repel and will move away from one another.
- Unlike charges attracts and moves towards one another
- Since the objects are coming towards each other, they are of opposite charges.

Explanation:
According to the impact theory, a glancing collision between a Mars-sized object and Earth led to the formation of the Moon. The iron core of Earth had formed before this collision, leading to the similarity between the composition of the Moon and Earth's mantle. After the collision, any iron core of the Mars-sized object would have been left behind on Earth and eventually merged with Earth's core. The Moon then formed out of the debris thrown into space by the collision.
The outer surface of the glass expands faster than the inside surface since glass is a fairly good thermal insulator. The outer surface tries to expand without the inner surface doing so at the same time. This is the secret of Pyrex glass. It is more conductive to heat and the inner and outer surface expand (and contract) at the same time.
Answer: Conversion of 9.83 m/s with a radius of 0.85 m into rotations per minute (rpm) is 
.
Explanation:
Given: Speed = 9.83 m/s
Convert m/s into m/minute as follows.
Radius = 0.85 m
Now, rotations take place in circular motion. So, the circumference of a circle is 
.
Therefore, circumference is calculated as follows.
Formula used to calculate rotations per minute (rpm) are as follows.
Thus, we can conclude that conversion of 9.83 m/s with a radius of 0.85 m into rotations per minute (rpm) is .
