True or false. it is better to buy a washer with a higher efficiency rating than a lower efficiency rating.

True

Explanation:

An efficiency rating refers simply to how efficient a machine is at using energy to do what it is supposed to do. Basically, you would divide the energy output by the total energy consumption. For example, a perfect efficiency washer would use 100% of the energy used to wash clothes. However, due to several reasons, machines cannot reach 100% efficiency but you can have higher efficiency ratings. While these machines may be more expensive upfront, overtime they end up saving money since they consume less energy to do the same amount of work as lower efficiency rated machines.

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
