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.

Alpha radiation consists of fast-moving helium particles, and Beta radiation consists of electrons. Although helium particles are tiny, and electrons even tinier, these still consistent matter. Alpha and Beta waves consist of matter.
Gamma radiation consists of pure energy in the form of electromagnetic rays, and therefore do not consist of matter.
The answer is A) It does not consist of matter
Your answer is B

Answer:
The distance travelled is 151.22m and it took 0.97s
Explanation:
Well, this is an ARM problem, so we will need the following formulas
where is the initial position (we can assume is zero), is the initial speed of 104 m/s, is the initial time (we also assume is zero), a is the acceleration of 107 m/s2, v is speed, x is position and t is time.
Now that we have the formulas, we know that when the electron stops it has no speed. Then we calculate how much time it takes to stop.
Finally, we calculate the distance travelled in this time
