Two resistances have lengths in the ratio 1:4 and radius 1:2,specific resistances in ratio 3:1. compare their resistances.Solution)Given lengths l1=1 l2=4Given radius r1=1 r2=2 Given specific resistances Ρ(rho)1=3 Ρ2= 1we know the R=Ρl/A R1/R2=3/1.
Accelaration is the rate of change of velocity.It defines how velocity is chaging with respect to time.
A thermodynamic process, in which the volume of gas always same is known as isochoric process. In this process, the work completed by the body is zero. Therefore from first law
