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.
1. A block of aluminum that has dimensions 1.16 cm by 3.00 cm by 5.00 cm is suspended by a thread from a spring scale. Density of aluminum is 2702 kg /m3. A beaker full of oil (density 8.50 × 105 g/cm3) rests on a second scale, which reads 460.0 g. The block is then lowered so it is fully submerged in oil without touching the bottom of the beaker. What is the reading on the spring scale supporting the...

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...

An aluminum block of mass 9.0 kg is originally at a temperature of 25°C and 1 atm. It is then heated to a temperature of 67°C without any change in pressure. The specific heat of aluminum is 900 J/(kg · °C), its density is 2.70 103 kg/m3, and the coefficient of linear expansion is 24 ✕ 10 −6 /°C. (a) Determine the work done by the aluminum block.
