Answer:
e. Both the acceleration and net force on the car point inward.
Explanation:
If no net force acts on the car, the car must drive in a straight line, at constant speed.
As the acceleration is defined as the rate of change of the velocity vector, this means that it can produce either a change in the magnitude of the velocity (the speed) or in the direction.
In order to the car can follow a circular trajectory, it must be subjected to an acceleration, that must go inward, trying to take the car towards the center of the circle.
The net force that causes this acceleration, aims inward, and is called the centripetal force.
It is not a different type of force, it can be a friction force, a tension force, a normal force, etc., as needed.

Have wavelengths that are longer than normal.
Answer:
The answer is a, the dirty cloths, water and detergent.
Explanation:
The answer is the above selected because the inputs basically represent the data that are passed through the system to generate the output.
In this case, the inputs are the aforementioned in the answer while the possible output would literally be the clean cloths.
Answer: C. T
Explanation:
Period is a unit of time; and in the context of waves or oscillations it is defined as <em>"the </em><u><em>time </em></u><em>elapsed between two equivalent points on the wave or oscillation".</em>
<em />
It is important to note Period (denoted by 
) is one of the most important factors (along with the amplitude, frequency and velocity) to describe and characterize a wave.
In addition, Period has an inverse relation with the frequency 
, this means that if we are given the frequency of a wave, we can inmediatly know its Period.
