Answer:
λ = 2.8 m
Explanation:
Given data:
Frequency of radio wave = 106.7 ×10⁶ Hz
Wavelength of radio wave = ?
Solution:
Formula:
Speed of wave = frequency × wavelength
speed of wave = 3×10⁸ m/s
by putting values,
3×10⁸ m/s = 106.7 ×10⁶ Hz × λ
Hz = s⁻¹
λ = 3×10⁸ m/s / 106.7 ×10⁶ Hz
λ = 3×10⁸ m/s / 106.7 ×10⁶ s⁻¹
λ = 0.028×10² m
λ = 2.8 m

Answer:
Collisions between gas particles are elastic; there is no net gain or loss of kinetic energy.
Explanation:
When a gas is paced in a container, the molecules of the gas have little or no intermolecular interaction between them. There is a lot of space between the molecules of the gas.
The gas molecules move at very high speed and collide with each other and with the walls of container.
The collision of these particles with each other is perfectly elastic hence the kinetic energy of the colliding gas particles do not change.
Answer:56.98496
Explanation:
half if diameter is radius or 1.55 and double the radius is 3.10 or the length of the diameter. you have a height given, so use the radius and heaight to plug it in the circular cylinder calculator and you get 56.98496
