Question

16. The speed of the cylinder at the instant
27c​

Answer 1

Answer:perabola

Explanation:

a=dv/dt

a=3/2 kx^1/2 v

and can be written as by putting the value of v

a=9/4 k^2 x^2

so a is proportional to x^2 which means graph will perabola

Answer 2

Explanation:

Speed is supposed to be the rms speed , given by v= 2 M3RT , Where R is gas constant.

Given that T=27+273=300Kelvin, R=8.31J/Kelvin and v=1920m/s putting all these to the expression,we get M=.02 i.e. Molar weight is .02gm/mole
