If a 10w lightbulb is left on for 168 hours , how many kilowatt - hours does it consume? A: 1.68 kwh

B: 168 wh

C: 16.8 wh

D: 16.8 kwh

0.55x745.7j and a calculator

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2

the displacement produced by the body.  

the amount of force subjected to the body.  

the angle between the direction of force and displacement

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
