The option which is not part of the kinetic molecular theory is that B. there is very little empty space in a gas.
As a matter of fact, gas particles are very tiny and they exist in mostly empty spaces.
Answer:
Average power of this circuit, P = 44.64 watts
Explanation:
It is given that,
The power factor of RC circuit,
The rms value of the AC voltage,
Impedance of the circuit, Z = 200 ohms
The average power of this circuit is given by the formula as follows :
P = 44.64 watts
So, the average power of this circuit is 44.64 watts. Hence, this is the required solution.
Reflection<span> is bouncing off a barrier or interface. </span>Refraction<span> is bending of light's path at the interface between two media. All angles are to be measured from the normal to the surface. The incident angle and the reflected angle are equal. The refracted angle may be larger or smaller than the incident angle.</span>
<span>The </span>index of refraction, n, is a ratio that compares the speed of light in a vacuum to the speed of light in another medium.
n = c/v where c = speed of light in a vacuum = 3x108<span> m/s</span>
The speed of light in all other media is less than in a vacuum. Therefore, n is always larger than one. It may be thought of as the measure of the slowness of light in a medium: the slower light travels in medium, the larger n will be for that medium. Since n divides speed by speed it has no units.
The frequency of light does not change as it enters a different medium, but its wavelength does. Since
v = fL where f = frequency and L = wavelength
then
v1/v2<span> = L</span>1/L<span>2
</span>EXAMPLE
1.
a. What is the speed of light in water, if water's index of refraction is 1.33?
b. If the wavelength of a ray of light in a vacuum is 1x10-6 m, what is its wavelength in water?
ANSWER
1.
a. n = c/v
1.33 = (3 X 108 m/s)/v
v = 2.26x108 m/s
b. v1/v2 = L1/L2
(2.26x108 m/s)/(3x108 m/s) = L1/(1x10-6 m)
L1 = 7.52x10-7 m
Answer:
The valence electrons determine an atom's reactivity.
Explanation:
The valence electrons is the electrons on the most outer layer of an atom. The higher the number of valence electrons, the bigger the reactivity of the atom. This means that when that atom is put with another substance and it reacts, it would react in a much more violent way than another atom with lower valence electrons.
