How Antman can breathe when his size is smaller then oxygen molecules?

1 answer:

8 0

Antman is fictional. However, in the case we were hypothetically assuming it was possible, he is the size of an ant which is not smaller than an oxygen molecule. When he goes into the quantum realm, he exists between the elemental particles (oxygen) and must use his mask to breathe.

Calculate the effective radiation dosage in sieverts for a 57 57 ‑kg person who is exposed to 4.2 × 10 9 4.2×109 particles of al

Rus_ich [418]

Answer:

Dose = 5.4 10⁻⁴ Sv

Explanation:

The radiation dose absorbed by the body is 81% of the incident radiation, which is the number of particles per energy of each particle

E = 0.81 n₀ E₀

E = 0.81 4.2 10⁹ 0.81 6.1 10⁻¹³

E = 2.075 10⁻³ J

Effective radiation dose

Dose1 = n x RBE

Dose1 = 2,075 10⁻³ 15

Dose1 = 3.1 10⁻² REM

The effective radiation dose in sievert

Dose = dose1 / m

Dose = 3.1 10⁻² / 57

Dose = 5.4 10⁻⁴ [j / kg]

Dose = 5.4 10⁻⁴ Sv

A 120-V motor has mechanical power output of 2.50hp. It is 90.0% efficient in converting power that it takes in by electrical tr

EastWind [94]

The current in this motor is equal to 17.27 Ampere.
The energy delivered to this motor in 3.00 hours is equal to 22.38 Megajoules.
At $0.110/kWh, the cost to run the motor for 3.00 hours is equal to $0.684.

<h3>How to determine the current (in A) delivered to the motor?</h3>

Assuming this electric motor is a single-phase motor and it operates by using DC current, its mechanical power output would be given by:

W = ηIV

Making current (I) the subject of formula, we have:

I = ηV/W

Substituting the given parameters into the formula, we have;

I = (2.50 × 0.746 × 1000)/(0.9 × 120)

I = 1,865/108

Current, I = 17.27 Ampere.

For the energy delivered to this motor, we have:

First of all, we would determine the power delivered to this motor as follows:

Power, P = IV

Power, P = 17.27 × 120

Power, P = 2,072.4 Watt.

Therefore, the energy delivered to this motor in 3.00 hours is given by:

Energy = power × time

Energy = 2,072.4 × 3.00 × 3,600 × 1/1000000

Energy = 22.38 Megajoules.

<h3>How to determine the cost?</h3>

At $0.110/kWh, the cost to run the motor for 3.00 hours is given by:

Cost = 0.110 × 22.38 × 0.278

Cost = $0.684.

This equation is known as the ideal gas law, and it can be used to predict the behavior of many gases at relatively low pressure

Masja [62]

The correct answer is
<span>C) either the pressure of the gas, the volume of the gas, or both, will increase.

In fact, the ideal gas law can be written as
</span> $pV=nRT$
<span>where
p is the gas pressure
V is its volume
n is the number of moles
R is the gas constant
T is the absolute temperature of the gas

We can see that if the temperature T increases, then the term on the right in the equation increases, therefore the term on the left should increase as well. In order for this to be possible, at least one between p and V should increase, or also both of them. Therefore, the correct answer is C.</span>
