A particle is traveling between two charged plates, separated by a distance d=1.5 mm, with an initial velocity of 18.5x104 m/s to the right as shown. It is observed that the particle is slowing down as it approaches the right plate. Assume that it is known that the particle is either an electron or a proton; which is it, you ask? You need to determine the type of particle first and then calculate the speed of the particle just as it arrives at plate on the right. Do NOT use scientific notation. Enter your answer as a decimal or whole number.

If a substance is in the gas phase, which of qualities of the gas will stay constant? a: volume b: mass c: shape d: position of particles

Under normal conditions, describe how increasing the temperatures effects the solubility of a typical salt

Beryl states that insulation with the smallest possible thermal conductivity is best to keep a house warm in winter, but worst for keeping a house cool in summer. sapphire insists the reverse is true: low thermal conductivity is good in the summer, but bad in the winter. which one, if either is correct? a. beryl, because low thermal conductivity results in low heat transfer. b. beryl, because low thermal conductivity results in high heat transfer. d. sapphire, because low thermal conductivity results in high heat transfer. e. neither, because low heat transfer is desirable both in summer and in winter.
