Evaluate each of the following situations and determine if an unbalanced force is present. choose all of the examples of unbalanced forces at work

.worth 20 points answer will markasap!

group of answer choices

a spacecraft moves in one direction at a constant speed.

a cyclist coasts downhill going faster and faster

a tennis racket hits a tennis ball and the ball bounces off.

a car turns right without slowing down.

that would be because of both gravity and friction. so     c

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

i think the answer is a and b

i wish you luck

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
