Answer: True
A water pump
belong to a positive displacement pump that provides constant flow of water at
fixed speed, regardless of changes in the counter pressure. The two main types
of positive displacement pump are rotary pumps and reciprocating pumps.
Moreover, water
pump is a reciprocating positive displacement pump that have an expanding
cavity on the suction side and a decreasing cavity on the discharge side. In
water pumps, the liquid flows into the pumps as the cavity on the suction side
expands and then the liquid flows out of the discharge as the cavity collapses
providing water in a pail.
Systolic pressure is measured when the heart beats and the muscles are contracted. Diastolic Pressure is to measure the pressure on blood vessels when the muscles of the heart are relaxing.
<h3><u>
Explanation:</u></h3>
Blood pressure is the pressure that is put on blood vessels and the heart muscles when it is pumping blood. The blood pressure can be categorized as high and low. Both of them come with medical consequence and require attention and treatment.
The measurement of blood pressure contains two values:
Systolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the arteries and contracted muscles of the heart. The pressure is measured to check if a person has a risks of heart strokes or attacks as well as kidney failures.
Diastolic Blood Pressure: When the blood is being pumped through the heart, a certain amount of pressure is applied on the blood vessels when the muscles are relaxing. The pressure is measured to prevent lack of oxygen that may cause severe damage to brain, heart and normal functionality of the individual.

Answer:
c) charges exert forces on other charges.
Explanation:
When two different materials are rubbed together, there is a transfer of electrons from one material to the other material so this causes one object to become positively charged and the other object is negatively charged so they will attract each other not repel each other. Charges exert forces on other charges i.e. opposite charges attract each other whereas similar charges repel each other so in both cases force are exerted on one another.
