Two circular plates with diameter 1.67 cm are used to form a parallel plate capacitor. The distance between the plates is 2.35 mm and the space between them is filled with air. Determine the magnitude of the electric field in this space when the capacitor is connected to a battery with a certain voltage that results in a charge of 2.40 pC on each plate.

What is the major limitation to the light microscope?

Why does karst topography exist in some geographic location? a. few climates have enough oxygen b. most regions have rock layers other than limestone c. in most regions, the soil is too thin d. the water is too acidic enough in most places

You have been hired to design a spring-launched roller coaster thatwill carry two passengers per car. the car goes up a 10-m highhill, then descends 15m to the track's lowest point. you'vedetermined that the spring can be compressed a maximum o 2.0m andthat a loaded car will have a maximum mass of 400kg. for safetyreasons, the spring constant should be 10% larger than the minimumneeded for the car to just make it over the top. a) what spring constant (k) should you specify ? b) what is the maximum speed of a 350 kg car if the spring iscompressed the full amount.
