PE = mgh
137200 = mg x 200
686 = mg
686/9.81 = m
m = 69.9286.... (idk how many decimals / sig. figs. you need)
<span>If Dr. Gavin decides that instead of conducting a 2 ´ 4 independent-groups factorial design, and he is going to conduct a 2 ´ 4 within-subjects factorial design, then the things that will change are the various independent groups which are involved.</span>
Answer:
The direction of the force at A and B is perpendicular to the walls of the container.
The direction of the force at C is down.
The direction of the force in D is up
The direction of the force at E is to the left.
The attached figure shows the forces exerted by the water at points A, B, C, D and E.
Explanation:
The water is in contact with the bowl and with the fish. It exercises at points A, B, C, D and E, but the direction is different from the force.
The fish has a buoyant force on the water and that direction is up. The direction of at point D is up.
The column of water on the fish has a downward force, therefore the direction of the force at point C is down. The water column to the right of the fish has a force to the left, and the direction at point E is to the left.
The water will exert a force on the walls of the container and this force at points A and B is a on the walls of the container.
The answer is D. Small object made of ice and dust that orbits the Sun and forms a coma as it approaches the Sun.
