Explanation:
the solar system is smaller then nebula nebula is smaller then a galaxie and a galaxie is smaller then a universe
Answer:
The answer is choice A and choice D
Explanation:
The answer below is just a joke, don't listen to them.

Answer:
Explanation:
From the question we are told that
The number of slits per cm is k = 
The order of the maxima is n = 1
The wavelength are 
The spacing between the slit is mathematically represented as
=> 
=> 
Generally the condition for constructive interference is
At

Question:
Diffusion is the movement of particles from high to low concentration. True or False
Answer:
True.
Explanation:
Diffusion is a process that allows the movement of substance or particles in and out of cells through a semipermeable membrane.
Diffusion is a process that allows the spread or movement of particles from the region of higher concentration to a region of lower concentration through a semipermeable membrane.
Diffusion only occurs in gases and solution but not in solids, it also occurs only where particles can move freely.
Note: When particles move from the region of higher concentration to a lower concentration, it gives room for even, uniform and random distribution of particles.
For the answer to the question above, let us first start with relaxation time. it is the absence of an external electric field, the free electrons in a metallic substance will move in random directions so that the resultant velocity of free electrons in any direction is equal to zero. While the Collision time it is<span> the mean </span>time<span> required for the direction of motion of an individual type particle to deviate through approximately as a consequence of </span>collisions<span> with particles of type.</span>
