Answer:
The heat is 115478.4 J.
Explanation:
Given that,
Mass of water = 0.400 kg
Power = 200 W
Suppose, we determine how much heat must be added to the water to raise its temperature from 20.0°C to 89.0°C?
We need to calculate the heat
Using formula of heat

Where, m = mass of water
c = specific heat
Put the value into the formula


Hence, The heat is 115478.4 J.
Answer:
The magnitude of the second charge is
or 
Explanation:
The work done in bringing a charged particle from one point to another in the presence of some electric field is equal to the change in the electric potential energy of the charge in moving from one point to another.
The electric potential energy of some charge
at a point in the electric field of another charge
is given by the product of the amount of charge
and electric potential at that point due to the charge
.

The electric potential at that point is given by

where
is the Coulomb's constant.
Therefore,

Now, We have given two charges
and
, whose value is to be found.
When the two charges are infinitely dar apart, the electric potential energy of the system is given by

When the coordinates of position of the two charges are

The distance between the two charges is given by

The electric potential energy of the charges in this configuration is given by

The change in the electric potential energy of the system is equal to the work done to bring the system from inifinitely far apart position to given configuration.
Therefore,
