Based on your knowledge of the Doppler shift of light, what is the best definition of the Doppler effect? Group of answer choices

A change in the frequency light waves caused by the motion of the source relative to the observer

The increase in wavelength of light as the source of light approaches the observer

A constant frequency of wavelength produced by an object that is moving in space

when it gains or loses electrons

0.19 m/s and 0.45 m/s

this could be newton#'s law of cooling. the cooling curve is exponential

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
