Which of the following statements correctly describes how the jet stream effects local weather? A.) Air pressure south of the jet stream is greater than north of the system.

B.) Clear nice weather follows along the jet stream as its winds move eastward.

C.) As the jet stream moves southward, it will bring with it colder temperatures.

D.) The jet stream moves storms in to areas with its slow low level winds.

1kg of water needs to recieve 4200j of energy to go from 90 degrees to 91 degrees. what is the specific heat capacity of water? what are the units?

If a negatively charged particle is placed at rest in an electric potential field that increases in the positive x-direction, what will the particle do? a. accelerate in the positive x-direction b. remain at rest c. accelerate in the negative x-direction

Aparticle of mass m is placed in a one-dimensional box of length l. the box is so small that the particle’s motion is relativistic, so that e p2/2m is not valid. (a) derive an expression for the energy levels of the particle using the relativistic energy–momentum relation and the quantization of momentum that derives from connement. (b) if the particle is an electron in a box of length l 1.00 1012 m, nd its lowest possible kinetic energy. by what percent is the nonrelativistic formula for the energy in error?
