Answer: a system
Explanation: just did the test
You can compare the velocity of the car, 60 mph, with the velocity that a mass would acquire when falls from certain height.
First, convert 60 mph to m/s:
60 miles/h * 1.60 km/mile * 1000 m/km * 1h/3600s = 26.67 m/s
Second, calculate from what height a body in free fall reachs 26.67 m/s velocity when hits the floor.
free fall => Vf^2 = 2g*H => H = Vf^2 / (2g)
H = (26.67m/s)^2 / (2*9.8 m/s) = 36.2 m
If you consider that the height between the floors of a building is approximately 3.6 m, you get 36.2 m / 3.6 m/floor = 10 floors.
Then, you conclude that the force of impact is the same as driving you vehicle off a 10 story building.
Answer:
False
Temperature is the flow of heat energy from one object to another.
Explanation:
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.
