Answer with Explanation:
We are given that the mathematical form of wave
a.We have to find the speed of propagation of this wave
In given mathematical form
k=Wave number
=Angular frequency
A=Amplitude
We know that
Speed of propagation of the wave=
b.Differentiate w.r.r t
The velocity of a point on the string as a function of x and t is given by
Answer:
Because there is nothing out in space , the sound waves from one astronaut's whistling can't travel over to the other astronaut's ears.
It is because carbon dioxide traps the solar radiation which then warms up the atmosphere, not allowing the radiations to get deflected back in the outer space.. that's what is happening to our own planet the greenhouse effect.. which is also increasing the GLOBAL Temp of our planet too
Answer:
Explanation:
Hold time is referred as the minimum time after active edge of clock after which data must be stable so hold violation will cause the incorrect data to be added.
In such circuit the first thing that can be done to fix this will be :
- Reset the clock to the start/endpoint to make end point clock arrive earlier.
- Insert a buffer chain to increase the propagation time.
- Add delays
