Given the average heart rate of a human is 7.00 beats per minute and the average volume flow of blood pumped out by the heart to the body is 70.0 mL/beat. (A) Determine the average flow rate for blood in units of milliliters per minute(mL/min) A person suffers a severe laceration that allows all the blood that is pumped out of the heart to be lost per beat, determine the time, in units of seconds it takes for a person to (b) lose all the blood from their body(assume the total volume of blood in the human body is 4.80L for parts (b), (c), and (d) (c) lose 20% of the total volume of blood in the body(at this point a person suffers hypovolemic shock) (d)lose 50% of the total volume of blood in the body( at this point the heart will stop pumping, organs begin to shut down, and the person might end upa comatose state given the person is saved due to medical intervention

Why is the average density not a "good" measure of density in this experiment?

Assume it takes 9.00 min to fill a 35.0-gal gasoline tank. (1 U.S. gal = 231 in.³) (a) Calculate the rate at which the tank is filled in gallons per second. gal/s (b) Calculate the rate at which the tank is filled in cubic meters per second. m³/s (c) Determine the time interval, in hours, required to fill a 1.00-m³ volume at the same rate. (1 U.S. gal = 231 in.³)

It's showing that b is not correct. Thank you for your help with this practice problem.

The rate of change of altitude in cm/s of a bird is given by a′(t)=650ln(t+3). What is the total change in altitude between t=3 and t=7? Round your answer to the nearest whole number and do not include units.

A partly-full paint can has 0.515 U.S. gallons of paint left in it. (a) What is the volume of the paint, in cubic meters? (b) If all the remaining paint is used to coat a wall evenly (wall area = 12.1 m²), how thick is the layer of wet paint? Give your answer in meters. (a) Number i 1.949 (b) Number i 312.1 Units m^3 v Units m^2

Consider a water tank that is being filled with rainfall at the top and is drained through a small hole atthe bottom. The change in volume can be modelled by considering the amount of water entering andleaving the tank (per unit of time) as followsdVdt= fin − fout.Here volume of water in the tank V is in litres, flow rate in fin is in litres per hour, flow rate out fout isin litres per hour and time t is in hours. Initially, the tank contains 50L of water: V (0) = 50.(a) Assume the rainfall throughout the day is getting heavier, such that, fin(t) = 10 + t andthat the tank is losing 10% of its volume of water per hour, such that, fout(V ) = 0.1V . Check bydirect substitution that the functionV (t) = 10(t + 5e−0.1t)satisfies the ODE and the initial condition.Now assume that the hole is slowly growing in size, so that the flow rate out increaseswith time:fout(V, t) = 0.1(1 + 0.1t)V.Solve the ordinary differential equation for V (t) with this flow rate out, using either separation…

The density of platinum is 21.45 x 103 kg/m3. a. Calculate the volume (in m3/atom) occupied per platinum atom b. Estimate the atomic diameter (in m);(The estimate uses the approximation that it is a cubic volume) c. Using this estimation, calculate the thickness of a metal foil (in m) containing 2.0 x 101 atomic layers of platinum.
