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

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
