Answer»

ANSWER :

Voltage of the motor of resistance 200 Ω and with a current of 2.2 A is 440 V.

Explanation :

Given :

Resistance in the motor, R = 200 Ω
Current in the motor, I = 2.2 A

To find :

Voltage in the circuit, V = ?

KNOWLEDGE required :

The equation for Ohm's law :

⠀⠀⠀⠀⠀⠀⠀⠀⠀V = IR

Where,

V = Voltage in the circuit.
I = Current in the circuit.
R = Resistance in the circuit.

Solution :

By using the first equation of motion and substituting the values in it, we get :

⠀⠀=> V = IR

⠀⠀=> V = 2.2 × 200

⠀⠀=> V = 22/10 × 200

⠀⠀=> V = 22 × 20

⠀⠀=> V = 440

Therefore,

Voltage in the circuit, V = 440 V

Answer» Given:- Force ,F = 50 N Displacement ,s = 2 m Displacement ,s' = 3m To Find:- Which one work more ,W Solution:- As we know that Work DONE is defined when force acting on the object produce some displacement . • W = Fs Where, W is the Work Done F is the Force s is the displacement Work done by Laxmi !! substitute the value we get → W = 50 × 2 → W = 100 J -------------(1) THEREFORE,work done by laxmi is 100 Joules. And, Work done by vinitha !! Substitute the value we get → W' = 50×3 → W' = 150 J ----------------(2) Therefore,work done by vinitha is 150 Joules. From Equation 1 & 2 we observe that work done by vinitha is more .

when laxmi applied a force of 50 newton on an object it undergoes a displacemnt of 2m when vinitha aplien the same forceon it it displaced 3m if so which one did more work

Answer»

Given:-

Force ,F = 50 N

Displacement ,s = 2 m

Displacement ,s' = 3m

To Find:-

Which one work more ,W

Solution:-

As we know that Work DONE is defined when force acting on the object produce some displacement .

• W = Fs

Where,

W is the Work Done

F is the Force

s is the displacement

Work done by Laxmi !!

substitute the value we get

→ W = 50 × 2

→ W = 100 J -------------(1)

THEREFORE,work done by laxmi is 100 Joules.

And,

Work done by vinitha !!

Substitute the value we get

→ W' = 50×3

→ W' = 150 J ----------------(2)

Therefore,work done by vinitha is 150 Joules.

From Equation 1 & 2 we observe that

work done by vinitha is more .

Answer» Explanation: The human eye, it is the most valuable and sensitive sense ORGAN which help us to see the beauty and the colorful world around us. It is similar to a camera. We all have been gifted with two eyes which gives a wider field of view. Structure of a Human Eye The eye is spherical in shape and has a diameter of 2.3 cm on an average. The internal structure of the eye includes- cornea, iris, pupil, lens, ciliary muscles, retina, nerve cells, optic nerve, and yellow spot, aqueous and vitreous humor, and suspensory ligament . Defects of a Human Eye There are few common eye disorders seen in all individuals and are caused by several factors. These conditions can be IMPROVED by the corrections. The defects include: Myopia – This is also called as the shortsightedness. A person with this eye defect can only see the nearby objects clearly compared to distant objects. This condition can be corrected using a concave lens. To know more about Myopia, visit here. HYPERMETROPIA – This is also called as the farsightedness. A person with this eye defect can only see the distant objects clearly compared to near objects. This condition can be corrected using a CONVEX lens. To know more about Hypermetropia, visit here. Presbyopia – This is an age-related condition caused due to the weakening of ciliary muscles, hardening of the lens, and reduced lens flexibility. A person with this defect usually finds DIFFICULTIES to focus on nearby objects unable to read or write. Cataract – This is an age-related condition caused due to the loss of transparency of the lens by erosion of lens proteins. It usually results in blurry vision, cloudy lenses and can be corrected by replacing the old lens with an artificial lens.
