Katie rubs a balloon against her hair. electrons from her hair travel to the balloon, giving the balloon a negative charge and her hair a positive charge. this image is courtesy of nasa when the negatively charged balloon is brought near the strands of katie's hair, they move to get closer to the balloon, without the balloon actually touching them. this shows that

electric attraction is a force that can act at a distance.

I did this on study island and accidently selected C and got it wrong!

Explanation:

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
