Answer:
please the answer below
Explanation:
A general electromagnetic plane wave, traveling in the x direction, can be expressed in the form:
(1)
1.
a. amplitudes
from (1) we can observe that E_0 and B_0 are the amplitudes.
2. frequency
3.
By replacing (1) we obtain:
4.
the wave respond to the followinf physical variables: amplitude, frequency, time and position, as we can see in (1).
hope this helps!!
Answer:
C. Replacing one gas by another under the same conditions, has no effect on pressure.
Explanation:
Ideal gas:
A gas is treated as an ideal gas if temperature is high and pressure is low.
Kinetic energy for ideal gas given as
So when temperature of gas is increases then Average molecular kinetic energy will also increases.
The size of molecule is negligible as compare to the dimension of container. It mean that volume occupied by molecule is less as compare to the volume of container.
The between molecules is perfectly elastic.
Ideal gas equation
P V = m R T
So the option C is not always true.
