1inch= 0.0254m,
1 pound force = 4.448N,
1 atmosphere = 105Nm^-2.
a)The recommended tyre pressure for a particular family saloon is 32 pounds force per square inch. Determine this pressure in atmospheres, giving your answer correct to three significant figures.
Planck’s constant, denoted by h, is the constant of proportionality between the energy E of a photon and the frequency ? of its associated wave. Thus
E = h?.
b)Frequency ?, wavelength ? and the speed of light c are related by the
formula v=c/ ? ,,,,,,Use dimensional analysis and the above relationship to show that [?]=T^-1.
c)Hence determine the dimensions of Planck’s constant
can any one shpw me step by step plz?
