The option that could be the hypothesis for this experiment is that D. Abstract paintings may elicit feelings of stress as students try to determine the meanings of the paintings; therefore, abstract paintings may cause college students to report lower feelings of peace.
<h3>What is a hypothesis?</h3>
It should be noted that a hypothesis simply means the proposed explanation made on the basis of limited evidence.
From the information, Smith is conducting an experiment to determine if paintings of landscapes produce more peaceful feelings than abstract paintings.
Therefore, the option that could be the hypothesis for this experiment is that abstract paintings may elicit feelings of stress as students try to determine the meanings of the paintings; therefore, abstract paintings may cause college students to report lower feelings of peace.

N2 = 3*n1
T2 = 2*T1
V1 = V2
(n2 * T2)/P2 = (n1 * T1)/P1
3 n1 * 2 T1 / P2 = n1 *T1 / P1
P2 = 6*P1
Since P2 is 6P1, it is 6 times greater than original pressure
Answer:
Y'now water vapor isn't half bad. It's like a vape but it can't affect your lungs. Anyway, Water vapor is water in gaseous instead of liquid form. It can be formed either through a process of evaporation or sublimation.
We can solve the problem by requiring the equilibrium of the forces and the equilibrium of torques.
1) Equilibrium of forces:
![T_1 - W_p - W_s + T_2 =0](https://tex.z-dn.net/?f=T_1%20-%20W_p%20-%20W_s%20%2B%20T_2%20%3D0)
where
![W_p = (90kg)(9.81 m/s^2)=883 N](https://tex.z-dn.net/?f=W_p%20%3D%20%2890kg%29%289.81%20m%2Fs%5E2%29%3D883%20N)
is the weight of the person
![W_s = (200kg)(9.81 m/s^2)=1962 N](https://tex.z-dn.net/?f=W_s%20%3D%20%28200kg%29%289.81%20m%2Fs%5E2%29%3D1962%20N)
is the weight of the scaffold
Re-arranging, we can write the equation as
![T_1 = 2845 N-T_2](https://tex.z-dn.net/?f=T_1%20%3D%202845%20N-T_2)
(1)
2) Equilibrium of torques:
![T_1 \cdot 3 m - W_p \cdot 2 m - T_2 \cdot 3m =0](https://tex.z-dn.net/?f=%20T_1%20%5Ccdot%203%20m%20-%20W_p%20%5Ccdot%202%20m%20-%20T_2%20%5Ccdot%203m%20%3D0)
where 3 m and 2 m are the distances of the forces from the center of mass of the scaffold.
Using
![W_p = 883 N](https://tex.z-dn.net/?f=W_p%20%3D%20883%20N)
and replacing T1 with (1), we find
![2845 N \cdot 3 m - T_2 \cdot 3 m - 833 N \cdot 2 m - T_2 \cdot 3 m=0](https://tex.z-dn.net/?f=2845%20N%20%5Ccdot%203%20m%20-%20T_2%20%5Ccdot%203%20m%20-%20833%20N%20%5Ccdot%202%20m%20-%20T_2%20%5Ccdot%203%20m%3D0)
from which we find
![T_2 = 1128 N](https://tex.z-dn.net/?f=T_2%20%3D%201128%20N)
And then, substituting T2 into (1), we find
