2 of 3 5. There is an acid that smells like dirty laundry. When alcohol is added to it and the mixture is heated, no
change is visible, but a new odor of sweet apples fills the room. Which of the following is the best
explanation for this observation?
A chemical change has taken place and no new substance was produced.
b. A physical change has taken place and no new substance was produced.
C. A chemical change has taken place and a new substance was produced.
d. A physical change has taken place and a new substance was produced.

An electron is traveling with initial kinetic energy k in a uniform electric field. the electron comes to rest momentarily after traveling a distance d. (a) what is the magnitude of the electric field

It may seem strange that the selected velocity does not depend on either the mass or the charge of the particle. (for example, would the velocity of a neutral particle be selected by passage through this device? ) the explanation of this is that the mass and the charge control the resolution of the device--particles with the wrong velocity will be accelerated away from the straight line and will not pass through the exit slit. if the acceleration depends strongly on the velocity, then particles with just slightly wrong velocities will feel a substantial transverse acceleration and will not exit the selector. because the acc
