P = I²R          

where P = Power in Watts, I = Current in Ampere, R = Resistance in ohms.

P = 36<span>² * 3.9 = 5054.4
 
P </span>≈ 5100 watts.

Silk flexibility would be considered a trait. TRUE OR FALSE
wel
The answer would be true.

Explanation:
Although some silk in is more flexible than others, there are many varieties. There are high medium and low flexibility. Even though there are different levels, it is still considered a trait. Again, the answer in True.

Hope this helped you. I did some research on this before, so this should be correct. If you aren’t satisfied then you can ask me a question! Have a nice day.

LiRa [457]

Answer:

The change in energy of the gas during the process is -1.83\times 10^{2} joules.

Explanation:

We can represent this process by the First Law of Thermodynamics, in which gas does work on its surroundings and absorbs heat from there to describe its change in energy. In other words:

Q_{in} - W_{out} = \Delta E

Where:

Q_{in} - Heat absorbed by the gas, measured in joules.

W_{out} - Work done by the gas, measured in joules.

\Delta E - Change in energy, measured in joules.

If we know that Q_{in} = 1.36\times 10^{2}\,J and W_{out} = 3.19\times 10^{2}\,J, the change in energy of the gas is:

\Delta E = 1.36\times 10^{2}\,J-3.19\times 10^{2}\,J

\Delta E = -1.83\times 10^{2}\,J

The change in energy of the gas during the process is -1.83\times 10^{2} joules.
