Question 4. 4.The candles melted by the qpplication of heat. What Change took place
when solid candles became liquid?

A. chemical
B. mechanical
C. no change
D. physical

A. chemical

it is not mechanical because mechanical contains machinery it is not know changed because it has nothing to do with it does not do anything it is not physical because physical is for body so that is why it's chemical

the bal will not change its velocity.

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
