If a scientist is studying a model that is a widely accepted theory about the position of planets and sun, the model would most likely help the scientist to understand facts that can't be easily observed. That will make the correct answer to be C.
Answer:
16.00L
Explanation:
First you calculate the number of moles in the system:
To find the new volume of the system you use the following formula for an isobaric procedure:
hence, the new volume is 16.00L
If the springs are connected together from end to end, they are arranged in series. For springs in series, the forces are additive.
Spring 1: F1 = k1(Δx1)
Spring 2: F2 = k2(Δx2)
Spring 1: F3 = k3(Δx3)
Total Force = k1(Δx1)+k2(Δx2)+k3(Δx3)
Total Force = (k1+k2+k3)(Δx,total)
The spring constants are added together and multiplied with the total length of elongation to find the total force acting on it.
Answer:
The answer is potential energy
Explanation:
The potential energy is the energy possessed by a body by virtue of it position
For example the water at the top of the dam is being held at a height h above the bottom of the dam
Then the potential energy
PE= weight of the water* the height
PE= m*g*h
Answer:

.
b) The change in angular position is:
c) The tangential speed of a point on the rim of the turn-table:
d) The tangential and normal components of the acceleration of the turn-table:
![a_{n} = (0.365\times 10^{-3}\,m)\cdot \left[(0.421\,\frac{rev}{s} )\cdot (\frac{2\pi\,rad}{1\,rev} )\right]^{2}](https://tex.z-dn.net/?f=a_%7Bn%7D%20%3D%20%280.365%5Ctimes%2010%5E%7B-3%7D%5C%2Cm%29%5Ccdot%20%5Cleft%5B%280.421%5C%2C%5Cfrac%7Brev%7D%7Bs%7D%20%29%5Ccdot%20%28%5Cfrac%7B2%5Cpi%5C%2Crad%7D%7B1%5C%2Crev%7D%20%29%5Cright%5D%5E%7B2%7D)
The magnitude of the resultant acceleration is:
