Question

Suppose you were kidnapped and held

prisoner by space invaders in a completely

isolated room, with nothing but a digital

watch, your school ring, and your long-

silver chain necklace of known length.

Explain how you might determine

whether this room is on earth or on

moon? Specify in the explanation the

function or use of each of the objects

stated.

Direction: Read the questions and problems carefully. Test 1: 5pts each - Modified True or False [Write true on the blank if the statement is TRUE. If FALSE, write false and supply the correct answer. Ex1. True 1. Strain is a unitless ratio. Ex2. False, Strain 2. Stress is a unitless ratio. 1. Since oil is more viscous than water, oil flows faster than water. 2. In Pascal's principle, the weight of the object that is partially or completely immersed in a fluid is equal to the weight of the displaced fluid. 3. Water is considered incompressible. 4. Oil floats on the surface of water because oil is denser than water. 5. In a damped harmonic motion, the particle oscillates with equal amplitude. 6. In a steady flow, the fluid flows at a constant speed. Test II: 20 pts each - Explanation 1. A ball of mass m is slowly and carefully placed inside a container full of water as shown below. Would there be a change in the fluid pressure as experienced by the fish swimming at the bottom of the container? Explain you answer. lite Certification Date: 1 February 2021.

(15 pts) The small piston of a hydraulic lift as shown in the figure has a cross-sectional of 3.00 x 104 m² and its output plunger has a cross-sectional area of 2.00 x 102 m². The lift uses hydraulic oil that has a density of 8.50 x 10² kg/m³. What downward force of magnitude F₁ must be applied to the small piston for the lift to raise a load (car and output plunger) whose weight is 1.50 x 104 N when the bottom surfaces of the piston and the plunger are at the levels with height difference of 1.5 m? 2. (15 pts) On a water-filled tank, a ball displaces 3.45 x 10³ m³ volume of water. a) What bouyant force is exerted on the ball? b) If the tank is filled with oil instead of water, what volume of oil would it displace if the oil has a density of 8.00 x 10² kg/m³?
