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

Which technique uses constructive feedback effectively?

giving feedback in front of a group

pointing out weaknesses first, then acknowledge the good points of a person's idea

focusing on the specific problem at hand rather than the person

focusing on what happened in the past and how to build on it

Answers

Answer:

focusing on the specific problem at hand rather than the person

Explanation:

When one receives a constructive feedback from someone, one of the ways to effectively use such feedbacks is to focus on the specific problem at hand rather than focusing on the personality of the person.

If you focus on the person, there is tendency that you might form bias that would hinder you from being objective in accepting and putting such constructive feedback into effective use.

Focusing on the person might make you discard the feedback and see it as an attack or destructive, especially if you've previously had an unpleasant encounter with the person people.

All other options given are not part of the technique that uses constructive feedback effectively.

The answer is: focusing on the specific problem at hand rather than the person

The correct answer is:

C) focusing on the specific problem at hand rather than the person

can a baby stay in a stomach for 4 months?

Answers

Answer:

well it is in the stomach for 9 moths so.......

Explanation:

Answer:

I'm not sure what you're asking but here are some answers to help you:

-

All premature babies are small, require complex medical care, and may face serious complications both in the NICU and at home. A baby born 3 to 4 months early, though, will face far different complications from a baby born 1 to 2 months early.

-

By all means, let your sleeping baby sleep. Once babies learn to roll over onto their tummies, a milestone that typically happens between 4 and 6 months but can be as early as 3 months, there's usually no turning them back (especially if they prefer snoozing belly-down)

Name two disinfectants that are unsafe for salon use

Answers

Answer:

Treponema and papillidam

Explanation:

Treponema and papillidam ae unsafe to salon use.

Which are salon drugs?

Three salons were found to have unsafe amounts of formaldehyde in the air while using specified products, and OSHA cited the salon owners for failing to protect their staff from excessive formaldehyde exposure.

Additionally, OSHA cited and fined salons and other establishments (such as beauty schools) for using formaldehyde-containing or -releasing products and for not adhering to the guidelines in OSHA's formaldehyde standard (e.g., testing the air to determine formaldehyde levels, providing protective equipment, providing training).

Additionally, OSHA examined a number of items and discovered formaldehyde in them even though they were marked "formaldehyde free" or did not mention it on the label. OSHA issued citations to the producers and sellers of these goods for mislabeling the goods.

Therefore, Treponema and papillidam ae unsafe to salon use.
