The aorta is a major artery, rising upward from the left ventricle of the heart and curving down to carry blood to the abdomen and lower half of the body. The curved artery can be approximated as a semicircular arch whose diameter is 6.1 cm. If blood flows through the aortic arch at a speed of 0.27 m/s, what is the magnitude (in m/s2) of the blood's centripetal acceleration?

Answers

Answer 1

Answer:

2.39m/s2

Explanation:

To get the magnitude of the blood's centripetal acceleration in the aortic arch, we use

a = (V^2) / d

where: a = aortic arch's blood's centripetal acceleration

            V = the speed of the blood

            d = diameter of the aorta

    Since it is semicircular of the arch, so we use the radius

So, r = d / 2

V = 0.27 m/s

r = 6.1 cm / 2 = 3.05 cm

convert cm to m (100cm = 1m)

3.05cm / 100cm = 0.0305 m

a = (0.27 m/s)^2 / 0.0305 m

= 0.0729m/s / 0.0305 m

= 2.39m/s2

Answers

Answer:

C.  push-ups

Explanation:

In order to know the answer, it is best to define what "muscular strength" and "endurance" are.

Muscular strength is related to a person's ability to lift a particular object with weight while endurance refers to a person's ability to tolerate by lifting that object without getting drained.

Improving both muscular strength and endurance is possible through "resistance training." This can be done by using equipment like dumbbells, medicine ball, resistance bands and the like. Nevertheless, this can also be done by using your own body weight.

Using your own body weight in exercising is possible such as push-ups. This can enhance both of your muscular strength and endurance.
