To every action, there is always an equal and opposite reaction.Force always occurs in pairs. Consider two bodies A and B, force on a body A by B is equal and opposite to the force on the body B by A.i.e,...

threshold wavelength where photoelectrons have no energy, i.e. Work function = hc/wavelength.Rearrange for wavelength and substitute. Wavelength = 2*10^-7 m.

Root mean squared speed is given by v(rms) = (3kbT/m)^(0.5) = 501.68. Student should show how to calculate the mass of each particle (m = (0.016)/0.5(6.01x10^23)), convert degrees celsius into kelvin and ...

Newton's Second Law: F=maa=v-u/tUsing SUVAT equations: v²= u²+2asv (final velocity)=0 u(inital velocity)= v s=d Rearranging gives: -v²=2ad a=-v²/2d Therefore F=...

E=F/Q. F= 20*(1.6910^-19)=3.3810^-18NF=ma m=9.1110-31 kgTherefore, a = 3.71 * 10^12 m/s^2Since v^2= u^2 + 2as and s= 0.5m,Then v=1.9310^6 m/s
