Answer:
They accelerate.
Explanation:
whether an object is ar rest or in motion, when external, unbalanced forces act on it, the object accelerates, as stated in Newton's second law:
where F is the net force acting on the object, m is its mass, and a its acceleration. Therefore, if there are unbalanced forces acting on the object, the object will accelerate. This means that an object at rest will start moving (in the direction of the net force), while an object already in motion will increase (or decrease, depending on the direction of the force) its velocity.

Answer:
9517.2 lbm
Explanation:
Electricity consumption = 14000 kWh/year
Fuel consumption = 900 gal/year
Amount of CO₂ produced per gallon = 26.4 lbm/gal
Amount of CO₂ produced per kWh = 1.54 lbm/kWh
Amount of CO₂ produced in one year
Reduction would be
The reduction in the amount of CO₂ produced is 9517.2 lbm
Answer:
η = 58.8%
Explanation:
Work is defined as the force applied by the distance traveled by the body.
where:
W = work [J] (units of joules)
F = force = 294 [N]
d = distance = 5 [m]
Efficiency is defined as the energy required to perform an activity in relation to the energy actually added to perform some activity. This can be better understood by means of the following equation.
