It is True that A sound wave causes particles of air to travel from the source of sound (e.g., the speaker) to the listener's ear : This is because of the collision of the air particles that is caused by the wave.

<h3>Meaning of sound wave</h3>

A sound wave can be defined as first a mechanical wave because it needs a medium to propagate.

A sound wave is an acoustic disturbance that is caused by the movement of energy traveling through a medium that is air, water etc.

In conclusion, It is True that A sound wave causes particles of air to travel from the source of sound (e.g., the speaker) to the listener's ear : This is because of the collision of the air particles that is caused by the wave.

Calculate the mechanical advantage if a machine allows you to move a 60 newton rock by only exerting 15 newtons of force.
murzikaleks [220]

Answer:

4 Newtons

Explanation:

  • I think it's 4 because mechanical advantage = output force/input force
  • So, it would be 60/15, which is 4 newtons

The basal metabolic rate is the rate at which energy is produced in the body when a person is at rest. A 75-kg (165-lb) person o
CaHeK987 [17]

Answer:

(a) Q = 142.67 W

(b) Basal Metabolic Rate = 178.33 W

Explanation:

(a)

We can find the heat radiated by the person by using Stefan-Boltzman's law:

Q = \sigma A (T^4 - T_{s}^4)\\

where,

Q = heat radiated per second = ?

σ = Stefan-Boltzman Constant = 5.6703 x 10⁻⁸ W/m².k⁴

A = Surface Area = 2 m²

T = Temperature of Skin = 30° C + 273 = 303 k

Ts = Temperature of room = 18° C +273 = 291 k

Therefore,

Q = (5.6703\ x\ 10^{-8}\ W/m^2.k^4)(2\ m^2)[(303\ k)^4-(291\ k)^4]<u></u>

<u>Q = 142.67 W</u>

<u></u>

(b)

Since the heat calculated in part (a) is 80 percent of basal metabolic rate. Therefore,

Q = (0.8)(Basal\ Metabolic\ Rate)\\Basal\ Metabolic\ Rate = \frac{Q}{0.8}\\\\Basal\ Metabolic\ Rate = \frac{142.67\ W}{0.8}

<u>Basal Metabolic Rate = 178.33 W</u>
