Which is not part of the first law of thermodynamics? a. the total amount of energy in the universe is constant. b. energy cannot be created or destroyed. c. energy can change forms d. energy cannot be converted into other forms

c)as speed changes, wavelength and frequency change.

everything changes!

answer; equivalent to a one(1) horsepower motor;

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
