PLEASE HELP ASAP URGENT Which statement is true of AC current?
A.
It uses a battery as a power source.
B.
It can easily be transformed from high voltages to low voltages.
C.
It is typically low voltage.
D.
the electrons are moving in one direction
E.
It was the first type of electric current invented.

B

i am not fully sure but i believe its the most accurate its either A or B

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

find the sum of the two horizontal vectors and the sum of the two vertical vectors
