The density of a body because four times its initial value .The new linear momentum will be

Options

A. `10^(-4)`
B. `10^(-2)`
C. `10^(-1)`
D. `10^(2)`

Answer

a

Explanation

Coefficient of volume expansion is given by
`gamma = (Delta p)/(p_(1) xx Delta T)`
where `p_(1)` is density , T is temperature
`gamma = (p_(1) - p_(2))/(p_(1) (T_(1) - T_(2))`
`= (10 - 9.7)/(10(100 - 0)) = 3 xx 10^(-4)`
Coefficient of linear expension is
`alpha = (gamma)/(3) = (3 xx 10^(-4))/(3) = 10^(-4)`
