The temperature of a gas is held constant whereas its volume is reduced.
The pressure the gas exerts on the walls of its container enhances because its molecules:
a) strike the container walls more often
b) strike the container walls with higher speeds
c) strike the container walls with greater force
d) all of the above
Ans- Strike the container walls more often
A medium is characterised by relative permittivity ε r =45 and relative permeability μ r =5. Determine the speed of e-m wave in the refractive and medium index of the medium.
