Answer:
No. If you apply a force in a chair, for example, you only will be able to move the chair if you beat the static frictional force. So, with that example, we can see that is not any type of force that can produce movement. The only force that produces movement is a result force which is non-zero.

An electron has a negative electric charge.
Answer:
Explanation:
Energy consumed per day = (2.2 x 1.5 + 4 x .075 x 5 + 2.5 x 1 + 2.3 )kWh
= 3.3 + 1.5 + 2.5 + 2.3
= 9.6 kWh
Energy consumed in a month = 9.6 x 30
= 288 kWh
cost = 288 x .105
= $ 30.24
b ) 288 kWh = 288 x 60 kW
= (288 x 60)/ 4.2 kcal
= 4114.28 kcal
coal required per month = ( 4114.28 / 7500) x (1 / .37 )
= 1.48 kg
coal required per month= 1.48 x 12
=17.76 kg
=
