Answer:
the statement given is False.
Explanation:
The pressure is defined by
P = F / A
The force of the air is its weight,
P = W_air / A
The weight of an air column on us depends on the energy of the molecules that is related to the temperature
E = 3/2 K T
When the air is warmer it has more energy so the molecules can move more distance and therefore the average density of the gas decreases, as the density decreases, the weight of the column on us also decreases, therefore the pressure low.
The correct statement is: When the air is hotter it has less pressure than when the air is cold.
It is summary the statement given is False
<span>From Ohm's law. V = IR. Where R = 2 Ohms. To calculate the induced current I; We need to calculate the electromotive force or voltage, V. From Faraday's law induced EMF = (The rate of change of magnetic flux density x Area)/ (changein time). Or EMF = BA/t. Where B = Bf - Bi. And BA = Bf* A - Bi* A.
Bf = 2.00 and Bi = 0.500 and t = 0.93s and the area, A = 7.1 cm^2 is 0.000071 m^2. 2
So Emf = 2.00 (0.000071) - 0.500(0.000071) /(0.93) = 1.0654 * 10^(-4)/ 0.93 = 1.1415 * 10^(-4).
Substituting into ohms law, we have,
I = (1.1415 * 10^(-4)) / 2 = 0.57075 * 10^(-4)</span>
Answer:
Atomic and molecular collision processes are the physical interactions of atoms and molecules when they are brought into close contact with each other and with electrons, protons, neutrons or ions. This includes energy-conserving elastic scattering and inelastic scattering.
