The correct answer of the question is : 0.001 s.
CALCULATION:
As per the question, the speed of sound v = 330 m/s
The frequency of the sound f = 990 Hz.
Let the wavelength of the wave is .
The wavelength of the wave is calculated as-
wavelength
=
= 0.33 m.
Now we are asked to calculate the time period.
The time period of the wave is reciprocal of frequency.
Mathematically time period T =
=
= 0.001 s.
As per the question, we need the period.
Hence, the period of the wave is 0.001 s.
For the given portion of the diagram, the sequence will go as follows:Sedimentary rock ----> Heat and pressure ---->
metamorphic rock --->
melting ----> magma
Therefore, from the given choices, the correct choice would be:d. P represents metamorphic rocks and Q represents melting
Note: For the complete rock cycle, refer to the attached image.
Speed of car = 130 km/hr = 130*5/18 = 36.11 m/s
Let the time taken for catching up be t,
Distance traveled by car = 36.11 t
Acceleration of police vehicle = 10.1 km/h/s = 10.1*5/18 = 2.81 m/
Distance traveled by police vehicle in time t =
Here u = 0, a = 2.81 m/
So, Distance = 0*t+
Comparing both the distances we have
So after 25.70 seconds police vehicle will catch car.
