All objects experience a buoyancy when they are immersed in a fluid. Buoyancy is: a. A downward force b. An upward pressure c. A downward pressure d. An upward force

QUESTION 33 Calculate the pressure when a 500 Newton block is sitting on one of its sides, which has an area of 0.5 m2 .    a. 1000 pascals   b. 202 pascals   c. 2000 pascals    d. 500 pascals

10. A container is filled with water as shown in the figure. Points A, B, C, and D indicates the pressure exerted by the liquid. Arrange the points based on the magnitude of the pressure exerted by the liquid in a descening order. D. Ignore the question number, just try it out! O D. B, A, C О В. С, А, D O C, A, B, D O A. C, B, D

5. DETAILS 777777.78 Pa MY NOTES A 70.00kg ballroom dancer wearing high heels accidentally steps on her partner's foot. If her entire weight was momentarily supported by the heel of her shoe, which has a surface area of 0.90 cm², what amount of pressure does this apply to her partner's foot? 762.22 Pa 76222.22 Pa 7622222.22 Pa ASK YOUR TEACHER Suppose she instead stepped on her partner's foot with her forefoot instead of her heel (i.e., larger surface area). Would the pressure on her partner's foot be greater, less than, or equal to if she stepped on her partner with her heel? The pressure from the forefoot would be greater than the pressure from her heel. The pressure from the forefoot would be equal to the pressure from her heel. The pressure from the forefoot would be less than the pressure from her heel.

1. What factors need to be taken into account when designing inflatable devices that float on water? Explain at least one factor relating to the gas itself, and at least one factor relating to the material holding the gas.

1. Piston A has a cross section of 1,600 cm² while that of B is 950 cm². B is higher that A by 2.6 m. if the intervening passages are filled with a liquid having a specific gravity of 1.24 and a force of 4.4 kN acting on B A) What must be the pressure at piston B B) What must be the pressure at piston A C) What must be the force exerted at piston A

A man is in a canoe in a pool. In the canoe with him there is a concrete block. If he takes the concrete block out of the canoe and drops it in the pool, what happens to the water level? A. it rises B. It sinks C. It stays the same
