7. In the case of intra-muscular injection of a medicament, its mass m(t) in blood changes with timeaccording to the law m(t) = "o (e-kt – e-rt). Here Mo is initial mass of the medicament, k is eliminationcoefficient and r is absorption coefficient. Calculate (a) the medicament mass in blood 3 hours afterinjection; (b) Find velocity of the medicament elimination v 3 hours after injection if k = 0,5 (1/hour), r =2 (1/hour) and Mo = 220 mg.Morr-k

There is relatively little space between atoms in solids and liquids, so that the average density of an atom is about the same as matter on a macroscopic scale - approximately 10^3 kg/m^3. The nucleus of an atom has a radius of about 10^-5m of that of the entire atom, and conatins nearly all mass of the atom. a) What is the approximate density, in kilograms per cubic meter, of a nucleus. b) One possible remnant of a supernova, called a neutron star, can have the density of a nucleus, while being the size of a small city. What would be the raduis, in kilometers, of the neutron star with a mass 10 times that of the Sun? The radius of the Sun is 7*10^8 m and its mass is 1.99*10^30 kg

Being the owner of an ice cream company Jane wants to know about theexistence of any relation between customers’ ages and the amount of ice cream (gr.) bought byeach customer. In this regard, she uses past one year’s data on age and daily sales and selectrandomly chosen 100 agents. Jane separates selected number of agents into two parts according totheir ages i.e., those who are aged below 18 years and those above 18 years and wonders primarilywhether the customers who are aged above 18 years purchase more amount of ice cream or notusing simple probability theory. Please explain whether the classical approach to probability isappropriate to reach a correct probability value, if not, explain the alternative approach to achieveit.
