Answer:
There are 5 significant figures in 52.887
5, 2, 8, 8, 7 --> all of these numbers are considered significant.
Answer:
The wave is traveling in the +x direction.
Explanation:
The equation of a wave is given by the formula as :
Here,
A is the amplitude of wave
is the phase of wave
is the angular frequency of the wave
We need to find the correct statement out of given options. The given equation can be rewritten as :
Here, the propagation constant is negative. So, the wave is moving in +x direction. Hence, the correct option is (a).
Answer and Explanation:
Tropical storm:
The point at which the tropical depression intensifies and can sustain a maximum wind speed in the range of 39-73 mph, it is termed as a tropical storm.
Hurricane:
A hurricane is that type of tropical cyclone which includes with it high speed winds and thunderstorms and the intensity of the sustained wind speed is 74 mph or more than this.
Hurricanes are the most intense tropical cyclones.
The only difference between the tropical storm and hurricane is in the intensity.
wavelength =wavevelocity
--——————
Frequency
Frequency = 1/T => 1 / 6.73 = 0.1486
Wave velocity = L/T => 3.75 / 6.73 = 0.5572
Therefore, wave length = 0.5572/0.1486 = 3.75m
