Answer:

It happens due to force of friction

Explanation:

If a body is performing a uniform motion and no external unbalanced force appears to apply on it, then the body will come to rest after certain time. The reason behind this is the force of friction that is applied in opposite direction of the motion. So, when there is no apparent unbalanced force it means that the only force acting on the body is the force of friction. This force of friction tends to stop the motion after some period of time, because it is acting in the direction opposite to that of motion.

Hence, the reason behind a body undergoing uniform motion eventually stops is Force of Friction.

Answer :

correct choice is option A

Motors convert electrical energy into mechanical energy. Generators convert mechanical energy into electrical energy.

Explanation :

Their difference is described as;

Premise MOTOR

The Motor Converts Electrical imperatives into vitality .
It uses control. (power)
In partner degree motor this is to be given to the curl winding
The Shaft of the motor is driven by the drawing in power made among loop and field.
Engine seeks after Fleming's left guideline.

GENERATOR

Generator changes over Mechanical essentialness to Electrical imperatives .
It produces control (electricity)
In the generator current is conveyed inside the curl winding.
The Shaft is associated with the rotor and is driven by mechanical power.
Generator seeks after Fleming's correct guideline. .

Fusion is the energy source of stars. The energy that is being released from the gas collapse into a protostar causes the center of the protostar to become extremely hot. Once the core is hot enough, nuclear fusion commences. The fusion reaction is a very structured process, releasing a huge amount of energy.

A convex lens of focal length 25 cm is in contact with a concave lens of focal length 50 cm. The equivalent focal length of this

Gwar [14]

The equivalent focal length of this combination-lenses should be +50 cm.

Given:

Focal length of convex lens, f₁ = +25 cm

Focal length of concave lens, f₂ = -50 cm

Calculation:

We know that the power of a lens is given as:

P = 1 / f

where, f is the focal length of lens

Now, the power of convex lens can be calculated as:

P₁ = 1/f₁

= 1/(25×10⁻² m)

= 100/25

= +4 D

Similarly, the power of concave lens can be calculated as:

P₂ = 1/f₂

= (1/-50×10⁻² m)

= -100/50

= -2 D

Thus, the power of the combined lenses can be calculated as:

P₍₁₊₂₎ = P₁ + P₂

= +4 D - 2 D

= +2 D

Now, the combined focal length of the lens can be calculated as:

f₍₁₊₂₎ = 1 / P₍₁₊₂₎

= 100 / 2 D

= +50 cm

Therefore, the equivalent focal length of this combination-lenses will be +50 cm.
