Answer:
Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.
The period of oscillation of the system is 12.56 s
Explanation:
The period of oscillation of a spring-mass system is given by
where
m is the mass attached to the spring
k is the spring constant
For the system in this problem, we have
m = 40 kg
k = 10 N/m
Substituting into the equation, we find

Diffraction is observable when the is smaller than the wavelength
Answer:
The value is
Explanation:
From the question we are told that
The first amplitude of the wave is
The first depth is
The second amplitude is
The second depth is
Generally from the spatial wave equation we have
=>
So considering the ratio of the equation for the two depth
=>
=>
=>
