a ball made in the same type of steel weighs 1.20 pounds.What is the diameter of the ball, in inches?

what is the density of aluminum if 3.50 cm3 has a mass of 9.45 g? Please report answer to the correct amount of significant figures.

A light metal rod has a mass of 0.610 oz/in of rod length. How many meters of rod length are needed to have a mass of 10.9 lbs? Assume that the rod has a constant diameter. Use 1 in = 2.54 cm in your calculations.

An automobile tire is shown in the figure below. The tire is made of rubber with a uniform density of 1.10 × 103 kg/m³. The tire can be modeled as consisting of two flat sidewalls and a tread region. Each of th sidewalls has an inner radius of 16.5 cm and an outer radius of 30.5 cm as shown, and a uniform thickness of 0.675 cm. The tread region can be approximated as having a uniform thickness of 2.50 cm (that i its inner radius is 30.5 cm and outer radius is 33.0 cm as shown) and a width of 19.4 cm. What is the moment of inertia (in kg m2) of the tire about an axis perpendicular to the page through its center? " 33.0 cm 16.5 cm Sidewall 30.5 cm Tread Enter a number. find the moment of inertia of the sidewall and the moment of inertia of the tread region. Each can be modeled as a cylinder of nonzero thickness. What is the inner and outer radius for each case? What is the formula for the moment of inertia for a thick-walled cylinder? How can you find the mass of a hollow cylinder?…

What is the mass of an empty graduated cylinder that weighs 94.86 g?

A silver sphere with a radius of 5.8 cm weighs the same as a certain aluminum cube. How long are the sides of this cube (in cm)?

A sphere made of either brass or aluminum has a radius r= 10cm. What is its mass?

The density of platinum is 21500 kg/m3 and that of aluminum is 2702 kg/m3. Find the ratio of the volume of 1.20 kg of platinum to the volume of 1.01 kg of aluminum.

Blood flows through the aorta at an average speed of v = 18 cm/s. The aorta is roughly cylindrical with a radius r = 17.0 mm. The volume rate of blood flow through the aorta is πr2v. Calculate the volume rate of blood flow through the aorta in L/min.

the average density of an atom is approximately 103 kg/m3. The nucleus of an atom has a radius about 10-5 times that of the entire atom, and contains nearly all the mass of the atom.  What is the approximate density, in kilograms per cubic meter, of a nucleus?
