2. 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.
Test III: 15 pts each - Problem Solving
1. (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?
Pwater = 1.00 x 10³ kg/m³
