I’ll give brainliest A 24 kg go-cart moves at a speed of 10.0 m/s. The engine exerts 50.0 N force to
accelerate the cart over a distance of 30.0 m.
(a)
What amount of work did the engine do on the cart?
(b)
What is the cart's final kinetic energy?
(c)
What will be the cart's final speed?

according to jean piaget, in what stage of cognitive development are children able to understand conservation task?

b. preoperational

just took it

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
