1.A hollow spherical shell has an inner radius r1 and outer radius r2. It is made of a material with density ?. Find the equation for its mass in terms of these three variables. 2.As we will learn, kinetic energy (K) has units kg•m2/s2. If we represent the mass of an object with m and its speed with v, we can write the kinetic energy as K = Ambv c, where A is a unitless constant. (a) What must the...
Suppose your hair grows at the rate 1/31 in. per day. Find the rate at which it grows in nanometers per second. Because the distance between atoms in a molecule is on the order of 0.1 nm, your answer suggests how rapidly layers of atoms are assembled in this protein synthesis.

At a resting pulse rate of 77 beats per minute, the human heart typically pumps about 71 mL of blood per beat. Blood has a density of 1060 kg/m3. Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body On average, what mass of blood does the heart pump with each heart beat? kg mass per heart...
While over the long run, the economy grows about 2 to 3% per year on average, over the shorter term, the economy goes through business cycles. Think about the growth rate of GDP, the inflation rate, and the unemployment rate over the last 12 quarters. Once you’ve looked at the data, can you draw conclusions about the state of the economy? Would you describe the economy as booming, recovering, or in recession during the last few years? Why? Use the AD-AS model...
