Math is the process of using the given information, along with
all the general stuff that you know, to find the missing information.
With no given information, we have no way to even guess at
an answer.
The smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.
<h3>
Emf induced in the coil</h3>
The emf induced in the coil is calculated as follows;
emf = dФ/dt
where;
- dФ is change in flux
- dt is change in time
0.12 = 5.7/dt
dt = 5.7/0.12
dt = 47.5 s
Thus, the smallest time interval in which the magnetic field can be turned on or off to induced the emf is 47.5 s.

If 
and 
are perpendicular, then their dot product is zero. This means
Solving for n is trivial; it follows that n = 3.
The moment of inertia is 
Explanation:
The total moment of inertia of the system is the sum of the moment of inertia of the rod + the moment of inertia of the two balls.
The moment of inertia of the rod about its centre is given by
where
M = 24 kg is the mass of the rod
L = 0.96 m is the length of the rod
Substituting,
The moment of inertia of one ball is given by
where
m = 50 kg is the mass of the ball
is the distance of each ball from the axis of rotation
So we have
Therefore, the total moment of inertia of the system is

Answer:
Se llama ángulo de incidencia -i- el formado por el rayo incidente y la normal. La normal es una recta imaginaria perpendicular a la superficie de separación de los dos medios en el punto de contacto del rayo. El ángulo de reflexión -r- es el formado por el rayo reflejado y la normal.
