Question

please give me the answer please.​

Answer 1

Required Answers:-

(1) False

• According to the formula for gravitational force, the Force is inversely proportional to the square of the distance between the two bodies.
• That means, if the distance is doubled, force decreases to 1/4th of the original force.

(2) Spectrometer

• All others are the different eyesight disorders due to decrease in the power of accomodation of the eye lens.

(3) Refracted ray

• In the process of refraction, refracted ray is the ray that passes through the denser medium. If the light is travelling from rarer to denser medium$.$

(4) Magnification - hi / ho

• Magnification is a way of expressing the ratio between the height of image and height of object.
• This helps us to know whether the image is magnified, diminished or same size.

(5) F' = x / 4

• The distance between the bodies is doubled, then the force will be F/4 by the formula.
• If initial force was x, then final force will be x/4.

Answer 2

Answer:

indident ray : rarermedium: denser medium
