If the comb and the paper are attracted to each other the charge on the paper, is D)must be positive
<h3>
Laws of electrical attraction</h3>
This states that
- Like charges attract
- Unlike charges repel
Now, given that a negatively charged plastic comb is brought close to, but does not touch, a small piece of paper. If the comb and the paper are attracted to each other the charge on the paper, this implies that both the negatively charged plastic comb and the paper have opposite charges.
Since the charge on the plastic comb is negative, this means that the charge on the paper must be positive
So, if the comb and the paper are attracted to each other the charge on the paper, is D)must be positive

If you kick a soccer ball, you exert a force on it in a certain direction.
The soccer ball will exert an equal amount of force but in the opposite direction, which is on your foot. This is felt as ‘recoil’
Answer
Force will be 1520.2604 N
Explanation:
We have given mass of the bullet m = 10.1 gram = 0.0101 kg
Distance S= 0.6 m
Final velocity v = 425 m/sec
Initial velocity u will be 0 m/sec
From third equation of motion 
We know that force is given by F = ma
So force = 0.0101×150520.833 = 1520.2604 N
True. In order for a chemical reaction between elements/compounds, the atoms within the chemicals must have sufficient energy in order to be able create a reaction.
