Answer:
Halving the wavelength doubles the frequency and, thus, doubles the energy of the incident photons. This doubles the energy given to each electron, nearly doubling its kinetic energy after it is free from the metal.
Answer:
5953.42 J
Explanation:
Given:
Initial volume,
= 100 in³
Final Volume,
= 10 in³
Initial pressure = 50 psia
Temperature = 100° F = 310.93 K
For isothermal reversible process, work done is given as:
Work done =
Where,
R is the ideal gas constant = 8.314 J/mol.K
or
Work done =
or
Work done = 5953.42 J
Answer:
"332.8 m/s" is the right solution.
