From the given equation we can deduce what changes will occur if the frequency of the sound is doubled
V= f (λ)
Speed = frequency. Wavelength
When the frequency is doubled, speed will not change. Because speed depends on factors like temperature, air pressure, density of the gas. Since all these factors are unchanged thus speed will remain unchanged
Frequency is the number of waves produced per second. Frequency and wavelength are inversely proportional .Thus, if the frequency is doubled the wavelength would be halved.
C) A crack in earth's crust where movement occurs. An example of this is the San Andreas Fault.
A) is repulsion
B) continental crust (lighter crust)
D) Hotspot
My guess is; The warmer ocean adds water vapor to the air mass.
I'm really sorry if I'm wrong
Let the rescue boat starts at an angle theta with the North
now its velocity towards East is given as
now in some time "t" it will catch the boy
so we will have
also we have
now we have
by solving above we got
