Two technicians are discussing electromagnetic induction. Technician A says that the induced voltage can be increased if the spe

ed is increased between the conductor and the magnetic lines of force. Technician B says that the induced voltage can be increased by increasing the strength of the magnetic field. Which technician is correct ? A. Technician A only B. Technician B only C. Both D. none of them

Answer:Both

Explanation:

There are three ways to increase the induced voltage in electromagnetic induction:

1) increase the speed at which the conductor moves through the magnetic field. This means that the lines of flux are cut more quickly and more emf is induced.

2) use stronger magnets which provides a stronger magnetic field and more densely packed lines of flux.

3) use a coil of multiple loops.

Hence both technicians were correct.

A massless rope passes over a massless pulley suspended from the ceiling. A 4-kg block is attached to one end and a 5-kg block i
borishaifa [10]

The acceleration on the 5kg block is 1.088m/s^2

Data;

  • mass(a) = 4kg
  • mass (b) = 5kg
  • acceleration of the 5kg block.
<h3>The Acceleration on the 5kg block</h3>

To solve this question, we just need to use Newton's second law of motion which states that "the time rate of change of the momentum of a body is equal in both magnitude and direction to the force imposed on it."

F_n_e_t = M_t_o_t_a_l * a\\F = ma\\F_n_e_t = mg\\

But then the force on both sides will be

mg = ma\\5g - 4g= (4+5) a\\(5-4)g = 9a\\g = 9a\\a = \frac{g}{9} \\a = \frac{9.80}{9} \\a = 1.088 m/s^2

The acceleration on the 5kg block is 1.088m/s^2

Magnetic field lines curve out from one pole and return to the same pole. Please select the best answer from the choices provide
Crank

Magnetic field lines always forms closed loop in such a way that it originates from North pole and then terminates back into the South pole

Inside the magnet we will draw the field lines from south pole to north pole

So it is not possible that magnetic field lines originates from north pole and again terminates at the same pole

So this is

FALSE

Assume that segment r exerts a force of magnitude t on segment l. what is the magnitude flr of the force exerted on segment r by
mrs_skeptik [129]
If we are talking on the force being exerted by a segment of a rope of lenght R on the right on a point M which is being also pulled from the Left by a segment of rope R  as shown in the figure attached. Then we invoke Newton's Third Law:
"Any force exerted by an object (in this case a segment of the rope) also suffers a equal and opposite force".
If we pick T_R=T whis is the tension exerted by the right segment then the left segment will also exert an equal and opposite force so we have that T_L=-T
