Answer:
The magnitude of the magnetic field created is 5 x 10⁻⁷ T
Explanation:
Given;
magnitude of current, I = 10.0 A
distance of the magnetic field, r = 4.0m
Apply Biot-Savart Law to determine the magnitude of of the magnetic field created;
where;
B is the magnitude of of the magnetic field
μ₀ is constant
I is current
r is the distance of the field
Therefore, the magnitude of the magnetic field created is 5 x 10⁻⁷ T
The puddle would warm up then begin to evaporate and then the gas could create a cloud the condensate and then make rain again to create another puddle then it happens all over again
-- heat the magnet red-hot in a flame
-- drop it on the floor several times, or beat it with a hammer
-- place it in a strong, rapidly alternating external magnetic field
Answer:
Your answer would be C <u><em>Hope this helps</em></u>
Explanation :
It is given that,
Potential energy, 
Power dissipated, 
We know that the power dissipated is given by :
I is the current passing through the phone.
or
I = 0.018 A
Hence, the current that passes through the phone is (1) 0.018 A.
