1.) Neglecting Grandma%u2019s mass, calculate the de Broglie wavelength of her 1958 Buick Century (mass = 1900 kg) as she drives by at 13.5 m/s (~30 mph).
2.) A capacitor is constructed of two 5.3 m2 parallel metal plates separated by an air gap of 0.010 mm. An electric potential of 25 V is applied to the capacitor. Calculate the following:
a. the capacitance of the structure.
b. the charge stored on the capacitor.
c. the electric field energy.
