Answer: For ideal machine efficiency = 1. Hence M.A = V. R. The V. R of an ideal machine and the practical machine is a constant or is the same for both
911.1×155.9 = 14,202.49
14,202.49 in 3 significant figures would be either 14,200 or 1.42×10^4
Answer:
Wave X is moving the fastest.
Explanation:
As we know that the speed of the wave is given as the product of frequency and wavelength
so here we will have
now for wave X
now the speed of this wave is
now for wave Y
now the speed of this wave is
now for wave Z
now the speed of this wave is
So correct answer will be
Wave X is moving the fastest.
