Answer:
a. E=8.97*10^{-21} J
b. v-He2 = 1.161 km/s
v-Ar2 = 369.74 m/s
Explanation:
(a) The average kinetic energy is given by

where KB is the Boltzman's constant and T is the temperature. For each molecule we have:

is the same for both type of molecules because is independent of the mass
(b)

where R is the constant of ideal gases, and M is the mass of the molecule. BY replacing for each type of molecule we obtain:

v-He2 = 1.161 km/s
v-Ar2 = 369.74 m/s
hope this helps!!
Answer:
L = 1.023 H
Explanation:
given,
radius of the cylindrical solenoid = r = 0.6 m
Number of turns = N = 600
Length = l = 0.5 m
Current in the cylindrical solenoid = 15 A
Inductance in the coil = ?
using formula




L = 1.023 H
the inductance L of the coil is = 1.023 H
Answer: u and v. Trust me I took the test and i was right
Answer:
The frequency , speed and wavelength of an electromagnetic wave are related by the formula
Speed = frequency x wavelength
frequency = speed / wavelength
substituting the values
frequency = 3 x #10 ^8# m /s / 1 x #10^15# m
= 3 x #10^-7# /s
The car produces 412.5 KG per m/s
