Bill was really bored at work. During his break, he decided to check his carotid artery. He placed both fingers on his neck and

Sergeeva-Olga [200]

Answer:

72 beats per minute

Explanation:

Heart beat causes the flow of blood round the body. This heart beat can be felt as pulse in the wrist or neck carotid artery. The heart rate which is measured in beats per minute (BPM) is used to determine the number of heart beats per minute.

You can calculate your BPM using the carotid artery found in the neck close to the windpipe.

Given that for 20 seconds, Bill had a total of 24 beats.

60 seconds = 1 minute.

Hence, Bill's BPM = (24 beats per 20 seconds) * (60 seconds per minute) = 72 beats per minute

Entropy is a measure of the _____ of a system. thermal energy mechanical energy disorder density

valina [46]

The answer is disorder. It would be really hard to explain without being too complicated, but the entropy is the number of possible states that a system can realize under given conditions.

What is an uncharged body? In physics (simple words)

andriy [413]

An uncharged body is a body that has equal magnitude of positive as well as negative charge on it. So as soon as some charged body is placed near it, the charged body induces negative charges on the uncharged body.

An object with mass 80 kg moved in outer space. When it was at location <7, -34, -7> its speed was 14.0 m/s. A single cons

Sergio [31]

Answer:

W = -2080 J

Explanation:

initial position vector of the object is given as

$r_i = 7\hat i - 34\hat j - 7 \hat k$

similarly final position vector is given as

$r_f = 12\hat i - 42\hat j - 11\hat k$

now the displacement of the object is given as

$\vec d = \vec r_f - \vec r_i$

now we will have

$\vec d = (12\hat i - 42\hat j - 11\hat k) - (7\hat i - 34\hat j - 7 \hat k)$

$\vec d = 5\hat i - 8\hat j- 4\hat k$

now the force on the object is given as

$\vec F = (200\hat i + 460 \hat j - 150 \hat k)$

so here in order to find the work done

$W = \vec F . \vec d$

$W = (200\hat i + 460 \hat j - 150 \hat k). (5\hat i - 8\hat j- 4\hat k)$

$W = 1000 - 3680 + 600 = -2080 J$

The Bob of a simple pendulum takes 0.25s to swing from its equilibrium position to one extreme. calculate it's period

mario62 [17]

Hence the period is 1 sec.

<u>Explanation</u>:

If the time taken by a single pendulum is 0.25 seconds. Then a pendulum will move to two extreme positions from one mean position only. That will means that the total time period is given by

T = 2 $\times$ 0.25 = 0.50 seconds.

A pendulum will oscillate from mean to the extreme, then extreme to mean, then mean to the extreme and again extreme to mean, so it will cover 2 cycles.

Hence, 2 $\times$ 0.50 = 1.
