Answer:

Explanation:
The strength of the electric field produced by a charge Q is given by

where
Q is the charge
r is the distance from the charge
k is the Coulomb's constant
In this problem, the electric field that can be detected by the fish is

and the fish can detect the electric field at a distance of

Substituting these numbers into the equation and solving for Q, we find the amount of charge needed:

Explanation:
soln,
weight=600N
mass=?
gravity=9.8 m/s²
now,
- mass=weight/gravity
- mass=600/9.8
- mass=61.22kg
hope it helps.

H
Explanation:
I think it's H hope that helps
It's easier for you to solve these than to try and read my solutions if I solve them.
Use this magic formula:
(period) · (frequency) = 1
If you handle the magic formula carefully and correctly, you can get these facts out of it:
-- Period = 1 / frequency
-- Frequency = 1 / period
Use the first one to solve #1.
Use the second one to solve #2.
