Answer:
"Offgassing"
Explanation:
According to my research on Kinesiology, I can say that based on the information provided within the question the process being described is known as "Offgassing". In other words this process is defined as when something gives off or releases a chemical, especially a harmful one, in the form of a gas into the air..

Answer:
Option D.
Value cannot be calculated without knowing the speed of the train
Explanation:
The speed of the beam can only be calculated accurately when the speed of the train is put into consideration. Based of the theory of relativity, the observer is on the ground, and the train is moving with the beam of light inside it. This causes a variation in the reference frames when making judgements of the speed of the beam. The speed of the beam will be more accurate if the observer is moving at the same sped of the train, or the train is stationary.
To get the correct answer, we have to subtract the speed of the train from the speed calculated.
Answer:
Work done, W = 1786.17J
Explanation:
The question says "A 75.0-kg painter climbs a 2.75-m ladder that is leaning against a vertical wall. The ladder makes an angle of 30.0 ° with the wall. How much work (in Joules) does gravity do on the painter? "
Mass of a painter, m = 75 kg
He climbs 2.75-m ladder that is leaning against a vertical wall.
The ladder makes an angle of 30 degrees with the wall.
We need to find the work done by the gravity on the painter.
The angle between the weight of the painter and the displacement is :
θ = 180 - 30
= 150°
The work done by the gravity is given by :
![W=Fd\cos\theta\\\\=75\times 10\times 2.75\times \cos30\\\\=1786.17\ J](https://tex.z-dn.net/?f=W%3DFd%5Ccos%5Ctheta%5C%5C%5C%5C%3D75%5Ctimes%2010%5Ctimes%202.75%5Ctimes%20%5Ccos30%5C%5C%5C%5C%3D1786.17%5C%20J)
Hence, the required work done is 1786.17 J.

I wish i can help you
Answer:
![F(x)=-3 N - (3N)x^2](https://tex.z-dn.net/?f=F%28x%29%3D-3%20N%20-%20%283N%29x%5E2)
Explanation:
The force is defined as the negative of the derivative of the potential energy:
![F=-\frac{dU}{dx}](https://tex.z-dn.net/?f=F%3D-%5Cfrac%7BdU%7D%7Bdx%7D)
If we use the potential energy function given in this problem:
![U(x)=3.00 x + 1.00 x^3](https://tex.z-dn.net/?f=U%28x%29%3D3.00%20x%20%2B%201.00%20x%5E3)
and we calculate the force, we get:
![F(x)=-\frac{d}{dx}(3x+x^3)=-3-3x^2](https://tex.z-dn.net/?f=F%28x%29%3D-%5Cfrac%7Bd%7D%7Bdx%7D%283x%2Bx%5E3%29%3D-3-3x%5E2)
So, the force is
![F(x)=-3 N - (3N)x^2](https://tex.z-dn.net/?f=F%28x%29%3D-3%20N%20-%20%283N%29x%5E2)
