First of all, the question is vague as you haven't mentioned the medium of propagation of the wave, which is extremely crucial.
For example light travels at <span>299,792</span> km/second in vacuum, but in certain semiconductors, it travels as slow as 9 km/second. Sound, ocean and seismic waves don't exist in vacuum at all.
If you mean the maximum possible speed any of these options can attain in any medium of choice for the different options, then the answer would be
b. radio waves, which travel exactly at the speed of light in vacuum (299,792 km/second) and with an almost similar(slightly less) speed in air. (Radio waves are nothing but electromagnetic waves with low frequency)
Answer:
Explanation:
The process is isothermic, as P V = constant .
work done = 2.303 n RT log P₁ / P₂
= 2.303 x 5 / 29 x 8.3 x 303 log 2 / 1 kJ
= 300.5k J
This energy in work done by the gas will come fro heat supplied as internal energy is constant due to constant temperature.
heat supplied = 300.5k J
specific volume is volume per unit mass
v / m
pv = n RT
pv = m / M RT
v / m = RT / p M
specific volume = RT / p M
option B is correct.
Answer:
Explanation:
If F is the applied force and θ is the applied angle from horizontal with positive angle below the horizon
Fnet = Fcosθ - μ(mg + Fsinθ)
The only variable you've actually given us is the friction coefficient.
You'll have to plug your own numbers in.
Remember, if the applied force is acting towards the floor, the normal force is increased as will be the friction force. The net force will decrease.
If the applied force is acting upward, the θ angle will be negative and the normal force is decreased along with the friction force. The net force will increase.
The correct answer is C. amplitude.
Have an awesome day!
the answer is d thats what i think
