Which pair of properties apply to both sound and electromagnetic waves? a) both waves carry energy and refract. b) both waves are longitudinal and carry energy. c) both waves are transverse and need a medium. d) both waves carry energy and do not need a medium to travel through.

A. Both waves carry energy and refract is the correct answer.

Explanation:

A) Both waves carry energy and refract.

Explanation:

Sound waves are longitudinal waves, and electromagnetic waves are transverse waves. So as they are a different type of wave we discard options B and C.

Also sound waves unlike electromagnetic waves, they do need a medium to propagate, which discards option D.

This leads us to the correct option that is A. Both waves carry energy and refract.

All waves are a perturbation that carries energy. Also, refraction occurs in both types of waves, this because both change direction when moving from one medium to another.

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
