A 1.00-kg beaker containing 2.00 kg of oil (density = 916 kg/m3) rests on a scale. A 1.50-kg block of iron is suspended from a spring scale and is completely submerged in the oil (see figure below). Find the equilibrium readings of both scales.
A beaker of mass MB, containing volume V of pure water, is at rest on a horizontal scale in a lab. A block of aluminum metal, mass mAl, is hanging from a spring scale and is completely immersed in the water. (a) [10 pts] Draw a fbd of the metal block, and write Newton’s second law, putting in all your forces. (You will need to look up “buoyant force” in Chapter 14, which we skipped.) Draw a fbd of the...
A block of steel (density of 8.05 x 103 kg/m3) with a mass of 1.50 kg is suspended (in equilibrium) by an ideal spring scale. The block is completely immersed in water (density of 1.00 x 103 kg/m3). What is the reading in the spring scale?
A light spring of constant 177 N/m rests vertically on the bottom of a large beaker of water. A 4.42 kg block of wood of density 669 kg/m3 is connected to the top of the spring and the block-spring system is allowed to come to static equilibrium. What is the elongation ∆L of the spring? The acceleration of gravity is 9.8 m/s 2 . Answer in units of cm.

There is a beaker completely filled with water (beaker #1). Then in another beaker a block of wood is gently lowered into the beaker until it floats on its own (beaker #2). Both beakers are sitting on scales. Explain what happens to the reading on the scale after the block floats in the water (beaker #2), compared to the original reading (beaker #1). Assume any water that is displaced from the beaker drains to the floor. Limit your answer to...

A mass m1 = 6.6 kg rests on a frictionless table. It is connected by a massless and frictionless pulley to a second mass m2 = 3.7 kg that hangs freely. 1) What is the magnitude of the acceleration of block 1? 2) What is the tension in the string? 23.4 N Now the table is tilted at an angle of θ = 76° with respect to the vertical. Find the magnitude of the new acceleration of block 1. 2...
