(a) Explanation The area of the aluminum plates is 120 cm 2 , the thickness of paper is 0.10 mm , its dielectric constant is 3.5 , the thickness of glass is 2.0 mm , its dielectric constant is 7.0 , the thickness of paraffin is 10.0 mm and its dielectric constant is 2.0 . Write the expression for capacitance C = ∈ 0 A ( κ d ) (I) Here, C is the capacitance of the capacitor, ∈ 0 is the permittivity of free space, A is the area of the aluminum plate, κ is the dielectric constant and d is the distance between the plates. The area of the plate is fixed but the dielectric constant and thickness is variable. Thus, the capacitance depends on the value of κ d . Substitute 3.5 for κ and 0.10 mm for d to find κ d for paper κ d = 3.5 0.10 mm = 35 mm − 1 Substitute 7.0 for κ and 2.0 mm for d to find κ d for glass κ d = 7.0 2.0 mm = 3.5 mm − 1 Substitute 2.0 for κ and 10.0 mm for d to find κ d for paraffin κ d = 2 (b) To determine The minimum obtainable capacitance.

Dielectric Constant Of Water

Water constitutes about 70% of earth. Some important distinguishing properties of water are high molar concentration, small dissociation constant and high dielectric constant.

Electrostatic Potential and Capacitance

An electrostatic force is a force caused by stationary electric charges /fields. The electrostatic force is caused by the transfer of electrons in conducting materials. Coulomb’s law determines the amount of force between two stationary, charged particle…

A high-speed lifting mechanism supports an 881 kg object with a steel cable that is 22.0 m long and 4.00 cm^2 in cross-sectional area. Young's modulus for steel is 20.0 ⋅10^10 Pa. Determine the elongation of the cable.

Namor, from Wakanda Forever, sits on a throne at the bottom of the ocean in a city called Talocan (and Atlantis in the comics). Assuming he, including his gold headdress, has a density of 1085 kg/m3 and that Namor is surrounded by salt water with a density of 1027 kg/m3, what is Namor’s normal force while sitting underwater? Take Namor’s mass as 285. kg and solve as if he has a uniform density.

To get there they need to travel through an area of salt-water, which seems to also be a magical portal, before arriving in a dry area. Judging by the time Maui and Moana spend falling through the water, it seems they dive 3440. ft deep. Assume the portal is non-magical salt-water, with a density of 1027 kg/m^3. Given that the air pressure above the portal is 1.013 ⋅10^5 Pa, what is the pressure when they are 3440. ft deep? 1 m = 3.28 ft. Moana would have a surface area of 1.30 m2. How much force would be acting on her at the bottom of this portal?
