Answer:
F' = 800 N
Explanation:
The electrical force between charges is 400 N.
The electrical force between two charges is given by :

If q₁' = 2q₁, new force becomes,

So, the new force becomes 800 N.
Answer:
Magnetic dipole moment will be
Explanation:
We have given length of the cylinder , that is h = 5.51 cm = 0.051 m
And diameter of the cylinder d = 0.865 cm
So radius 
So volume of cylinder 
It is given there is uniform magnetization of 
We have to fond the dipole moment
Dipole moment is equal to
, here M is magnetization and V is volume
So
Since all of the appliances ... and everything else in the house that's
plugged into a wall outlet ... are all in parallel, they don't have any
effect on each other. They don't know about each other. The
question asks about the frying pan, so the toaster and the lamp
have no effect on the answer.
The frying pan has 120 V applied to it, and it produces 1592 watts
of heat.
Power = (voltage)·(current)
1592 watts = (120 v)·(current)
Divide each side by 120v:
Current = (1592 watts) / (120 volts)
Current = 13.27 Amperes
Answer:
no
Explanation:
because The properties of matter include any traits that can be measured,
Physical properties can be observed or measured.
Potential energy = mgh
Energy, U = 400J
g = 10m/s^2
m = A kg
h = U ÷ mg
= 400÷10A
= 40÷A
mass is not given
