A particle has an initial velocity of `9m//s` due east and a constant acceleration of `2m//s^(2)` due west. The distance coverd by the particle in the fifth second of its motion is :

A

0m

B

0.5m

C

2m

D

20m

Text Solution

Verified by Experts

The correct Answer is:
B
An ideal gas has only KE.
kinetic energy in `A=nxx(3)/(2)RT=(3)/(2)nRT=(3)/(2)PV`
kinetic energy in `B=(3)/(2)(2P)(2V)=4((3)/(2)PV)`
`therefore " Ratio" =1:4`
