How much power is required to push a box 4.0 m with a force of 150 n in 2.5s? a. 15w b. 1500w c. 240w d. 94w

the anser is (C) as 240 Watt

As we know that

As given in question

Force = 150 N

Distance = 4m

Then work is

So the answer is 240 watt

two charges are fixed in place on the x-axis as shown. the charge at x = 0 is negative and has magnitude q = 2 μcoulombs (1 μcoulomb = 10-6 coulombs). the charge at x = d, (d = +12 cm), is positive and has magnitude q = 4 μcoulombs. find a point x = xo along the x-axis at which the electric field is zero.

prolly a beacuse the momentuem the car has increases while going down hill
