Call

`[E]=[ML^(2)T^(-2)]=(5)`
`=(10)^(2)(5)^(2)=20` joules

Radioactivity of a sample at `T_(1)` time is `R_(1)` and at time `T_(2)` is `R_(2).` If half-life of sample is T, then in time `(T_(2)-T_(1)),` the nu

Correct Answer - B Let `R_(1)=N_(1)lamdaandR_(2)=N_(2)lamda` Mean life, `T=(1)/(lamda)` `R_(1)-R_(2)=(N_(1)-N_(2))lamda=(N_(1)-N_(2))(1)/(T)` So, number of atoms disintegrated in `(T_(2)-T_(1))` is `=N_(1)-N_(2)=(R_(1)-R_(2))T`

A particle is moing with a velocity of `10m//s` towards east. After 10s its velocity changes to `10m//s` towards north. Its average acceleration is:-

Correct Answer - B Acceleration `veca=(Deltavecv)/(Deltat)=(10hatj-10hati)/(10)` `=-hati+hatj` (west north) `|veca|=sqrt(1+1)=sqrt(2)` (north-west)

If in a system force (F), pressure (P) and time(T) is fundamental unit, then dimensional formulae for length will be:

`L=[MLT^(-2)]^(x)[ML^(-1)T^(-2)]^(y)[T]^(x)` `x+y=0 x-y=1` `-2x-2y+z=0` `x-(1)/(2) y=-(1)/(2) z=0`
