A large piece of jewelry has a mass of 132.6 g. A graduated cylinder initially contains 48.6 mL water. When the jewelry is submerged in the graduated cylinder, the total volume increases to 61.2 mL. (a) Determine the density of this piece of jewelry. (b) Assuming that the jewelry is made from only one substance, what substance is it likely to be? Explain.

(a) What is the mass, volume, and density of the yellow block?
First weigh it using the balance
Record the initial volume of water in the beaker
Drop the block inside the beaker
Record the final volume displaced by the block
Calculate the density of the block with the data in the simulations (b) What is the mass, volume and density of the red block? Do the same procedures as (a) (c) List the block colors in order from smallest to largest mass. (d) List the block colors in order from lowest to highest density. (e) How are mass and density related for blocks of the same volume?
A ) The figure shows a simple pump cylinder circuit. the cylinder must push a constant load of 170,000 N. The pump provides a real volume flow Qp = 140 l/min. Loss in the directional valve is calculated at 2 bar when the pump and cylinder are connected via this. The safety valve is set at 200 bar. the plant is filled with oil with specific gravity equal to 0.85. effective cylinder area is 100cm2 After the plant was put into operation. It was found that the speed of the cylinder was too great. It was desired that the specified load should be pushed by 0.2 m / s. It was decided that one should weld into the pipe before the cylinder, a fixed, sharp-edged throat piece (as indicated in the figure) in parallel with a non-return valve. 1) Calculate the diameter d of the opening in the larynx so that the load, when pushed, travels at the desired speed. Assume flow coefficient u M = 0.6 2) How much power in kW is lost in total between the points x and y in this circuit (see figure) when the load is pushed out at a constant speed and the choke is in place. B) How much power is lost in a pipeline with an inner diameter equal to 30 mm and a length of 100 m when the oil flow being transported is 0.24 m3 / min. The oil has a kinematic viscosity 1 = 20cSt and a density 3 p= 840kg/m == m ANSWERS: I have the answers to this question. but I just do not know how to solve them. here are the answers: A) 1) 7.23 mm 2) 12.6 kW B) 5.98 kW
1.A standard 1 kilogram weight is a cylinder 41.5 mm in height and 51.0 mm in diameter. What is the density of the material? (answer unit: kg/m^3) *
2.A crystalline solid consists of atoms stacked up in a repeating lattice structure. Consider a crystal as shown in Figure a. The atoms reside at the corners of cubes of side L = 0.160 nm. One piece of evidence for the regular arrangement of atoms comes from the flat surfaces along which a crystal separates, or cleaves, when it is broken. Suppose this crystal cleaves along a face diagonal, as shown in Figure b. Calculate the spacing d between two adjacent atomic planes that separate when the crystal cleaves. (answer unit: nm) *
