Passive transport is when molecules travel from HIGHER concentration to LOWER concentration through a concentration gradient.
Active transport is the OPPOSITE. So it travels from LOWER to HIGHER concentration through a concentration gradient.
There are also other differences, but this is the main difference.
Answer:

Explanation:
Given that,
Width of a one dimensional potential box, 
The energy of a particle in one dimensional box is given by :

h = Planck's constant
m = the mass of the proton
For minimum kinetic energy, n = 1


So, the minimum kinetic energy of the neutron is
. Hence, this is the required solution.
When a substance is heated, the molecules begin to vibrate faster and the space between molecules increases. So it would be speeding up.
Answer:
The detailed explanations is attached below
Explanation:
What is applied is the De brogile equation and the equation showing a relationship between Energy, speed of light and wavelength.
The explanation is as attached below.
Answer:
C) It increases to 2.0 cm
Explanation:
In a double-slit diffraction experiment, the distance on the screen between two adjacent maxima is given by

where
is the wavelength of the wave
D is the distance of the screen from the slits
d is the separation between the slits
In this problem, the initial distance between adjacent maxima is 1.0 cm. Later, the slit separation is cut in a half, which means that the new slit separation is

Substituting into the equation, we find that the new separation between the maxima is

So, the distance increases by a factor 2: therefore, the new separation between the maxima will be 2.0 cm.
