The correct answer to the question is : B) Generator.

EXPLANATION:

As per the question, the mechanical energy is converted into electrical energy.

All the power plants like thermal power plant, nuclear power plant and hydroelectric power plant use the same concept to produce electric energy.

Let us consider hydro power plant.

In hydro power plant, the water falling with high speed is allowed to fall on a turbine. The kinetic energy of the water rotates the turbine. The turbine is attached to a generator.

The coil of wire attached to it is rotated through a magnetic field and electricity is produced due to electromagnetic induction.

Hence, the correct answer to the question is generator which converts mechanical energy into electrical energy.

Who invented the wedge simple machine and why?
Lelu [443]

Answer:

Gene Sarazen began to win tournaments in 1935 with a new club he had invented that was specialized for sand play. He is hailed as the inventor of the sand wedge.

Explanation:

A wedge is a triangular shaped tool, and is a portable inclined plane, and one of the six classical simple machines. It can be used to separate two objects or portions of an object, lift up an object, or hold an object in place. It functions by converting a force applied to its blunt end into forces perpendicular (normal) to its inclined surfaces. The mechanical advantage of a wedge is given by the ratio of the length of its slope to its width.[1][2] Although a short wedge with a wide angle may do a job faster, it requires more force than a long wedge with a narrow angle.

The force is applied on a flat, broad surface. This energy is transported to the pointy, sharp end of the wedge, hence the force is transported.

The wedge simply transports energy and collects it to the pointy end, consequently breaking the item. In this way, much pressure is put on a thin area.

calculate the amount of work done by a person while taking a bag of mass 100kg to the top of the building hight 10m. The mass of
vredina [299]

Explanation:

Total mass=100+10=110

Total weight=mass×gravitational field strength

=110×10

=1100N

Work done=force×distance

=1100×10

=11000J

What is the frequency of a wave with speed 3m/s and wavelength 6m?
Ugo [173]

Answer:

f = 0.5 Hz

Explanation:

frequency = f

wave length = l

speed of wave = v

f = v/l → f = 3/6 = ½ = 0.5 Hz
