Answer: 0.66 V
Explanation:
Given
Magnetic field, B = 0.963 T
Instantaneous rare = 74.5 cm/s = 0.745 m/s
radius, r = 14.7 cm = 0.147 m
We will use the formula
emf = dΦ/dt
emf = d(BA)/dt
emf = d(Bπr²)/dt
if B is constant, then we can say
emf = Bπ d(r²)/dt on differentiating, we have,
emf = Bπ (2r dr/dt)
emf = 2πrB dr/dt substituting each values, we have
emf = 2 * 3.142 * 0.147 * 0.963 * 0.745
emf = 0.66 V
Therefore, the induced emf in the loop at that instant is 0.66 V
Answer:
A procedure according to the norms.
Explanation:
If possible, proceed to fix the leak in no more than 30 days from the moment it was discovered.
Otherwise, during the first 30 days develop a planification to backfit the leak or, if needed, retire the appliance. This should be executed within one year.
Answer: 13.33 m/s^2
Explanation:
Force is the product of mass of an object and its acceleration.
i.e Force = Mass x Acceleration
Since Force on object = 800N
Mass of object = 6Kg
Acceleration = ?
Then, Force = Mass x Acceleration
800N = 60Kg x Acceleration
Acceleration = (800N/60kg)
Acceleration = 13.33 m/s^2 (The unit of acceleration is metre per second square)
Thus, the objects accelerations is 13.33 m/s^2
