Evaluate the integrals (a) s (3x2 – 2x – 1) 5(x – 3)d. (b) write an expression for the volume charge density p(r) of a point charge q at the specific position) r' and very that the volume integral saul space p(r)dt is equal to q (c) a spherical shell of charge with radius r is described by the charge distribution par) = a8(r – r) where a is a constant. assuming the total charge of the shell is q, find the constant a.

the answer is definitely c.

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

the answer to this is proletariats.

hope this : )
