In which situation is no work being done? A. a person carrying a box from one place to another B. a person picking up a box from
Anastaziya [24]

Picking up a box, pushing a box along the ground, and pulling a box along the ground (B, C, and D) definitely involve work being done.

If a person CARRIES a box from one place to another, AND keeps it at the same height during the entire carry, then no work is done. ( A )

String linear mass density is defined as mass/unit length. Calculate the linear mass density in kg/m of a string with mass 0.3g
SIZIF [17.4K]

Answer:

Linear mass density,\lambda=2\times 10^{-4}\ kg/m

Explanation:

Given that,

Mass of the string, m = 0.3 g = 0.0003 kg

Length of the string, l = 1.5 m

The linear mass density of a string is defined as the mass of the string per unit length. Mathematically, it is given by :

\lambda=\dfrac{m}{l}

\lambda=\dfrac{0.0003\ kg}{1.5\ m}

\lambda=0.0002\ kg/m

or

\lambda=2\times 10^{-4}\ kg/m

So, the linear mass density of a string is 2\times 10^{-4}\ kg/m. Hence, this is the required solution.

Lasers are important to help mankind in many different reasons. Some of these reasons include laser hair removal, some kinds of eye surgery, and lasers are said to help with the military in the near future. Laser hair removal is usually used for getting rid of unwanted hairs. And is just a easy alternative to regular waxing or doing it yourself. Some types of eye surgery require lasers to complete them successfully. This is usually very very precise as lasers get the job done at pin point accuracy. Besides medical uses the U.S. military have been testing laser weapons on battleships to attack or defend oncoming missiles. This will most likely replace small firing cannons or flares.

I hope this helped you.

A gas within a piston–cylinder assembly undergoes a
IrinaVladis [17]

Answer:

W_{net}= -280.5 kJ

Q_{23}= 80.0 kJ

Explanation:

The net work of the cycle is the sum of works in each process.

<u>For the first process 1-2: </u> Let's apply the work definition.

W=\int pdV (1)

Now, we need the pressure. We know that pV=C, where C is a constant. Then  p_{1}V_{1}=10^{5}2=2*10^{5} [J]

So p=\frac{2*10^{5}}{V}

Let's put p in (1):

W_{12}=\int \frac{2*10^{5}}{V}dV=2*10^{5}\int \frac{1}{V}dV

W_{12}=2*10^{5}(ln(V_{2})-ln(V_{1}))=2*10^{5}(ln(0.2)-ln(2))=-460.5 kJ

Using the first law of thermodynamics we can find Q.

Q_{12}-W=\Delta U

Q_{12}=W+\Delta U=-460.5 + 100= -360.5 kJ

<u>Second process 2-3</u>

In this case, we have a constant volume, so the work done here is 0.

W_{23}=0

<u>Third process 3-1</u>

W_{31}=\int pdV=p\int dV=p(V_{2}-V_{1})

W_{31}=10^{5}(2-0.2)=180 kJ

Finally, the net work is:

W_{net}=W_{12}+W_{23}+W_{31}= -280.5 kJ

By the conservation of energy:

(Q_{12}+Q_{23}+Q_{31})-(W_{net})=\Delta E=0

Because there is no change in total energy.

So:

Q_{23}=W_{net}-Q_{12}= 80.0 kJ

It is a refrigerator because the net work is negative, it means it consumes energy.

I hope it helps you!
