What does it mean to say that an object is opaque? O A. It reflects all visible light.
O B. It absorbs all visible light.
O C. Light will transmit through it.
D. Light will not transmit through it.
The answer is (D light will not transmit through it )

asthenosphere and convection

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray

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
