State the equipartition theorem and use it to calculate the molar heat capacity in an isochoric process for: (i) a monoatomic gas; (ii) a diatomic gas. • state the relation between c, and cy for an ideal gas and use it to calculate the molar heat capacity in an isobaric process for: (i) a monoatomic gas; (ii) a diatomic gas. • consider an ideal gas which contains » moles of the monoatomic molecules and v moles of the diatomic molecules. (i) derive the molar heat capacity for the gas mixture in an isochoric process. (ii) derive the molar heat capacity for the gas mixture in an isobaric process. (iii) based on these calculations, derive the adiabatic coefficient. • consider a classroom where the air is at a temperature of 20°c and pressure of 1 atm. (i) using the equation of state for an ideal gas, estimate the average distance between air molecules in the classroom. (ii) using the random walk model for molecules, estimate the mean free path of air molecules in the classroom.

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

electromagnetic shielding is the practice of reducing the electromagnetic field in a space by blocking the field with barriers made of conductive or magnetic materials. shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment through which the cable runs. electromagnetic shielding that blocks radio frequency electromagnetic radiation is also known as rf shielding.

the shielding can reduce the coupling of radio waves, electromagnetic fields and electrostatic fields. a conductive enclosure used to block electrostatic fields is also known as a faraday cage. the amount of reduction depends very much upon the material used, its thickness, the size of the shielded volume and the frequency of the fields of interest and the size, shape and orientation of apertures in a shield to an incident electromagnetic
