WILL GIVE BRAINLIEST TO THE MOST CORRECT ANSWER The angle of incidence of a ray of light striking an equilateral triangular prisms ABC of refracting angle 60o is 40o. Calculate:

(i)the angle of refraction at the first face
(ii)the angle of emergence
(iii)if the light is incident normally on the first face AB, with the aid of a ray diagram, describe the path of this light as it passes through the prisms. Take μ = 1.5.

According to newton's second law, when the same force is applied to two objects of different masses, a the object with greater mass will experience a great acceleration, and the object with less mass will experience an even greater acceleration, b. the object with greater mass will experience a smaller acceleration, and the object with less mass will experience a greater acceleration, c. the object with greater mass will experience a greater acceleration, and the object with less mass will experience a smaller acceleration, d. the object with greater mass will experience a small acceleration, and the object with less mass will experience an even smaller acceleration.

When an object is heated it contracts. a. true b. false

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.
