Answer:
Explanation:
Magnetic field due to straight current carrying wire is given by the formula
now we will have for one side of the square at its center position given as
now for the we have for complete square loop it will become 4 times of the one side
Answer:
e
Explanation:
An object at rest has zero velocity - and (in the absence of an unbalanced force) will remain with a zero velocity. Such an object will not change its state of motion (i.e., velocity) unless acted upon by an unbalanced force.
Answer:
The electrical loads in parallel circuits each have the same voltage drop, with equals the total applied voltage of the circuit.
Explanation:
I did some research and the voltage drop across any branch of a parallel circuit is the same as the applied voltage.
Almost in every Physics books, momentum is denoted by P with small arrow(→) pointing towards right, placed on top of P.
I am guessing you asked about linear momentum.
Answer:
The emf is 0.574 volt.
Explanation:
Given that,
Magnetic field
Length = 75.0 m
Velocity = 255 m/s
We need to calculate the emf
Using formula of emf
Where, v = velocity
l = length
B = magnetic field
Put the value into the formula
Hence, The emf is 0.574 volt.
