Answer:
E) d/sqrt2
Explanation:
The initial electric force between the two charge is given by:
where
k is the Coulomb's constant
q1, q2 are the two charges
d is the separation between the two charges
We can also rewrite it as
So if we want to make the force F twice as strong,
F' = 2F
the new distance between the charges would be
so the correct option is E.
The speed of the snail is given by:
where S is the distance covered by the snail and t the time taken.
The snail in the problem moves by S=18 mm in t=24 s, therefore its speed is
Winds can pull warm air from a warmer area to a colder arena and rise the temperature. It can also do the opposite, bringing cold air from a colder area to a warmer area, dropping the temperature.
Answer:
No.
