Ahardworking ant must supply 0.00805 n to pull a small piece of fruit at constant velocity over a distance of 9.80 cm up a small hill to the entrance of the colony. if the coefficient of kinetic friction between the piece of fruit and the 15.8â° sloped hill is 0.400, calculate the work done by the ant by pulling the piece of fruit up the hill.

In physics, the definition of work is simply the product of force exerted and the displacement. Therefore in this case, work done by the ant is:

Work = 0.00805 N * 9.80 cm * (1 m / 100 cm)

Work = 7.889 x 10^-4 J

A - "Objects of the same charge attract." - False, they repel.

B - "Objects of the opposite charge repel." - False, they attract each other.

C - "Negatively charged objects have lost electrons." - False, if they have lost electrons they will become neutral or positively charged.

D - "Negatively charged objects have gained electrons." - True.
