The particle wave with a trapped quantum particle is quantized. Consider a particle trapped in a Cone-dimensional well of fixed size. Suppose you have a particle in the ground state. You also have a device allow you to add energy to the particle.(1) What is the amount of energy you can successfully add to the particle and make the particle jump to the next energy level, in eV. (Consider particle mass of 2.5 x 10-27 kg in a one-dimensional box with length 3.0 nm.)(2) If photon radiation is added to the particle, what is the frequency of the energy you should use? (3) Does the intensity of the photon radiation affect the jumping of the quantum particle?

(a) Evaluate the mean value of the voltage, v (volts) over an interval t = 2 to t = 10 seconds, where v = 6(1 - e-2t) Keep the answer as an exact value. [6 marks] (b) A gas is expanded in a piston according to the thermodynamics relation: PV1.4 = 1963, where P is the pressure and V the volume. The work done W by the gas is given by: V2 W = P dv V1 where V₁ and V₂ are the initial volume and the final volume of the gas respectively. Calculate W, the work done by the gas, if the volume V changes from 0.016 m³ to 0.09 m³. [6 marks]
