q=(n*e).....(i) where, q= charge, n=number, e= charge of an electron n=q/e....(i) (from equation i) given,q= +2.8mc= +2.8*10^-6 c we know, charge of an electron(e)=1.6*10^-19 c hence n= (2.8*10^-6)/(1.6*10^-19) = 1.75*10^13 so, 1.75*10^13number of charges

cause the air comes in thermal equlibrium with your body... and it depends upon the heat that your body looses...i guess so.
metals are the good conductor of heat. hence, metals can gain heat by contact. so, the cup with the metal spoon will cool faster.
if sin2x=3sin2y, prove that: 2tan(x-y)=tan(x+y) ( here, in sin2x, 2x is an angle., like there's a formula:sin2x=2sinxcosx and sin2y=2sinycosy; ....)
find the force exerted by these two equal charges by using f=(1/4*pi*epsilon)*(q1*q2)/r^2 if f1 is the force exerted by one charge q1 and f2 be the force exerted by another charge q2 which are equal in their magnitude(as you've mentioned) then f1=f2=f.
