You are movingto a new apartment. It takes you 2 seconds to lift a 200 N box and move it 1.5 meters. How much power did you exert? W = Fd and P=W/t\
400 W

150 W

300 W

600 W

150 W

Explanation:

We know that work is a product of force and distance, expressed as where W -work in Nm or Joules, F is exerted force in Newtons and is the perpendicular distance moved in meters. Substituting F with 200 N and d with 1.5 m then work will be W= 200*1.5= 300 Nm= 300

Since power is defined as rate of work per unit time then power

Hence, the power exerted is 150W

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.
