Answer:
The speed of sound in this gas is 409.6 m/s.
Explanation:
The length of the column changes from 20 cm from resonance to resonance. Thus,
The length change from one resonance to resonance. so, there is 1 loop change. So,
ΔL = 1 loop = λ/2
ΔL = 20 cm (given)
Also, 1 cm = 0.01 m
So,
ΔL = 0.2 cm (given)
The wavelength is:
λ = ΔL×2
λ = 2x0.2 = 0.4 m
Given:
Frequency (ν) = 1024 Hz
<u>Velocity of the sound in the gas = ν×λ = 1024×0.4 m/s = 409.6 m/s</u>
Answer:Kinetic energy is the energy of motion. All moving objects have kinetic energy. When an object is in motion, it changes its position by moving in a direction: up, down, forward, or backward. 3. A force is a push or pull that causes an object to move, change direction, change speed, or stop.
Explanation: Not sure if that's what you meant but that's the answer I can give you.
Answer:
i) Angle of Reflection = Angle of Incident
ii) Total Angle = 2x Angle of reflection/incidence
iii) The incident ray, reflected ray and the point of incidence lie in the same plane
