Answer:
clockwise
Explanation:
We shall apply Lenz's law to find the direction of induced current in case magnetic field changes. According to this law , direction of current induced is such that it will try to oppose the cause which produces the induced current .
In the present case, downward magnetic field decreases so current will be such that downward magnetic field increases . It can happen when clockwise current is induced. So clockwise current will be induced.
Answer:
Explanation:
Given that
We know that from continuity equation
So
Now from energy equation
Q=6.17 x 0.08
Answer: hi your question is incomplete attached below is the complete question
answer :
magnitude of acceleration : | a | = g = 9.81 m/s^2
direction : a = - g j
Explanation:
Neglecting Air resistance
magnitude of acceleration :
| a | = g = 9.81 m/s^2
Direction of acceleration
a = - g j ( given that the direction of acceleration is against the acceleration due to gravity i.e. in the opposite direction )
Answer:
If the particle is an electron
If the particle is a proton,
Explanation:
Initial speed at the origin,
to +ve x-axis
The particle crosses the x-axis at , x = 1.5 cm = 0.015 m
The particle can either be an electron or a proton:
Mass of an electron,
Mass of a proton,
The electric field intensity along the positive y axis , can be given by the formula:
If the particle is an electron:
If the particle is a proton:
