Block A in the figure (Figure 1) hangs by a cord from spring balance D and is submerged in a liquid C contained in beaker B. The mass of the beaker is 0.750 kg ; the mass of the liquid is 1.55 kg . Balance D reads 3.75 kg and balance E reads 7.50 kg . The volume of block A is 4.00×10−3 m3 .

A. What is the density of the liquid? Express your answer in kilograms per cubic meter.

B. What will the balance D read if block A is pulled up out of the liquid? Express your answer in kilograms.

C. What will the balance E read if block A is pulled up out of the liquid? Express your answer in kilograms.

(Figure 1) illustrates an Atwood's machine. Let the masses of blocks A and B be 7.50 kg and 1.50 kg , respectively, the moment of inertia of the wheel about its axis be 0.220 kg⋅m2, and the radius of the wheel be 0.120 m. There is no slipping between the cord and the surface of the wheel. Part A Find the magnitude of the linear acceleration of block A. Express your answer with the appropriate units. Part B Find the...

Constants (Figure 1)Block 1, of mass m1 = 0.600 kg , is connected over an ideal (massless and frictionless) pulley to block 2, of mass m2, as shown. For an angle of ? = 30.0 ? and a coefficient of kinetic friction between block 2 and the plane of ? = 0.400, an acceleration of magnitude a = 0.400 m/s2 is observed for block 2. Part A Find the mass of block 2, m2. Express your answer numerically in kilograms.

A small block on a frictionless, horizontal surface has a mass of 2.70×10−2 kg . It is attached to a massless cord passing through a hole in the surface (Figure 1). The block is originally revolving at a distance of 0.300 m from the hole with an angular speed of 2.33 rad/s . The cord is then pulled from below, shortening the radius of the circle in which the block revolves to 0.150 m. Model the block as a particle....

A block of mass m = 1.50 kg slides down a 30.0∘ incline which is 3.60 m high. At the bottom, it strikes a block of mass M = 6.20 kg which is at rest on a horizontal surface (Figure 1). (Assume a smooth transition at the bottom of the incline.) The collision is elastic, and friction can be ignored. Part A Determine the speed of the block with mass m = 1.50 kg after the collision. Express your answer...

A green hoop with mass mh = 2.4 kg and radius Rh = 0.14 m hangs from a string that goes over a blue solid disk pulley with mass md = 2.3 kg and radius Rd = 0.08 m. The other end of the string is attached to an orange block on a flat horizontal surface that slides without friction and has mass m = 3.6 kg (see Figure 1). The system is released from rest. (a) What is magnitude...
