What is the largest voltage you can safely put across a resistor marked 98 Omega-0.5 W ?

What is the safest voltage you can put across a 98 Omega-0.5 W resistor ?

What highest voltage can you safely put across a 98 Omega - 0.5 W resistor?

The work function for sodium metal is 2.46eV . Determine the cutoff wavelength for sodium? Strategy: The cutoff frequency v_(0) is related to the work function through the relation v_(0) = W_(0)//h . This corresponds to a cutoff wavelength of lambda_(0) = (C )/(v_(0)) = (C)/(W_(0)//h) = (hc)/(W_(0)) . wavelength grater than lambda_(0) for a metal with work function W_(0) produce no photoelectric effect.

Find the maximum kinetic enegry of photoelectrons liberated form the surface of lithium by electromagnetic radiation whose electric component varies with time as E = a(1+cos omegat) cos omega_(0)t , where a is a constant, omega = 6.0.10^(14)s^(-1) and omega_(0) = 360.10^(15)s^(-1) .
