This morning on the way to school when you picked up your iced latte your barista added 600g of coffee to 100g of ice. When you got to school the ice had all melted. To prove you didn't get swindled you massed your drink when you got to school and found it was 700g. Represent this situation accounting for conservation of matter. Explain your reasoning.

According to newton’s first law of motion, which force is expected to cause a body to accelerate?

In order of decreasing light-transmitting capabilities of materials, which is the correct sequence? a. transparent -> translucent -> opaque b. opaque -> transparent -> translucent c. opaque -> translucent -> transparent d. translucent -> transparent -> opaque

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?
