Suppose you were kidnapped and heldprisoner by space invaders in a completelyisolated room, with nothing but a digitalwatch, your school ring, and your long-silver chain necklace of known length.Explain how you might determinewhether this room is on earth or onmoon? Specify in the explanation thefunction or use of each of the objectsstated. 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.True1. Strain is a unitless ratio.Ex2.False, Strain2. 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 immersedin 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 - Explanation1.A ball of mass m is slowly and carefully placed inside a container full of water as shown below. Wouldthere be a change in the fluid pressure as experienced by the fish swimming at the bottom of thecontainer? Explain you answer.liteCertification Date: 1 February 2021.Recertification due date: 24 January 2024For verification of the certificate pleaseaccess www.gcl-intl.com (Certificationcheck and type the registration number)SDF-CAS-302-40-00UKASMANAGEMENTGCLINTERNATIONAL9001Registration No. 52Q18778ONUNIVEHD,1962Republic of the PhilippinesCEBU NORMAL UNIVERSITYOsmeña Blvd., Cebu City, 6000, PhilippinesCollege of Arts and SciencesTelephone No.: (+63 32) 254 1452 loc. 140Email: cnucas@cnu.edu.phWebsite: www.cnu.edu.phCOLLEGE OF ARTS AND SCIENCESCebu Formal HaibersityULCH2.

(15 pts) The small piston of a hydraulic lift as shownin the figure has a cross-sectional of 3.00 x 104 m²and its output plunger has a cross-sectional area of2.00 x 102 m². The lift uses hydraulic oil that has adensity of 8.50 x 10² kg/m³. What downward force ofmagnitude F₁ must be applied to the small piston forthe lift to raise a load (car and output plunger) whoseweight is 1.50 x 104 N when the bottom surfaces ofthe piston and the plunger are at the levels withheight 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 oilhas a density of 8.00 x 10² kg/m³?Pwater = 1.00 x 10³ kg/m³GCLCertification Date: 1 February 2021Recertification due date: 24 January 2024For verification of the certificate pleaseaccess www.pcl-intl.com (Certificationcheck and type the registration number)INTERNATIONAL UKASMANAGEMENTISO 90015965Registration No. 52Q18778SDF-CAS-302-40-00
