Answer

OPTION A is correct

a)increases by a factor of more than 2.

Explanation:

adiabatic process is a process that takes place without the transfer of heat or mass between a thermodynamic system and its surroundings.

It is a process in which no heat transfer takes place. It does not denote that the temperature is constant.

Then from an adiabatic system,

we know that

PV= constant

PV^γ= constant

γ=ratio of specific heat for the gas

Where P= pressure of the system

V= volume of the system

We can say P= 1/(V^γ)

Where γ >1

Which means the pressure is inversely proportional to the volume raise to power of gamma sign and whenever the pressure increases the volume decreases with V^γ.

The question says the volume is decreased by factor of two then V^γ will also decreased by factor of 2.

That means (2^γ) > 2

Since our γ > 1 Therefore, the pressure increases by a factor of more than 2.

Answer:

<em>a) increases by a factor of more than 2.</em>

Explanation:

In an adiabatic process,

PV^{Y} = constant

we can say that the volume is inverse to the pressure as

V^{Y}∝ \frac{1}{P}

where

P is the pressure

V is the volume

Y is the adiabatic index, and it is always greater than 1

If volume V is decreased by a factor of 2, then it is actually decreased by a factor of 2^{Y} in proportion to the pressure, and since Y is always greater than 1, it is actually decreased by a factor greater than 2 in proportion to the pressure.

This means that the pressure will also increase by a factor greater than 2.

How does the resulting cell at the end of asexual reproduction compare to the original cell
lina2011 [118]

1. At the end of asexual reproduction the resulting cell is an exact genetic copy of the original cell.

2. During inter phase the cell copies its DNA, and grows to an appropriate size where it is safe for the cell to split.

3. After meiosis, the resulting daughter cells are 4 genetically different haploid daughter cells.

4. During sexual reproduction, two haploid gametes join in the process of fertilization to produce a diploid zygote. The two haploid gamete bring different traits together, they also shares some DNA. This makes each daughter cell unique.

A locomotive is pulling 15 freight cars, each of which is loaded with the same amount of weight. The mass of each freight car (w
VMariaS [17]

Answer:

298,220 N

Explanation:

Let the force on car three is T_23-T_34

Since net force= ma

from newton's second law we have

T_23-T_34 = ma

therefore,

T_23-T_34 = 37000×0.62

T_23= 22940+T_34

now, we need to calculate

T_34

Notice that T_34 is accelerating all 12 cars behind 3rd car by at a rate of 0.62 m/s^2

F= ma

So, F= 12×37000×0.62= 22940×12= 275280 N

T_23 =22940+T_34= 22940+ 275280= 298,220 N

therefore, the tension in the coupling between the second and third cars

= 298,220 N

A blender with a total resistance of 6 ohms runs on a voltage of 190 volts. How much current does it use? NEED TO KNOW ASAP PLEA
faltersainse [42]
<h2>Hello!</h2>

The answer is 31.67 Amps.

<h2>Why?</h2>

To solve the problem, we need to use Ohm's Law equation, which states that:

V=IR

Where,

V, is the voltage (in volts)

I, is the current (in Amps)

R, is the resistance (in Ohms)

We are given the following information:

Voltage=190v\\Resistance=6\Omega\\

So, using Ohm's Law equation and substituting the given information, we have:

V=IR\\\\190v=I*6\Omega\\\\I=\frac{190v}{6\Omega}=31.67Amps

Hence, we have that the current used by the blender is 31.67Amps.

Have a nice day!
