The equation used to calculate the weight of an object on a plant is F = ma. "F" is the force measures in Newtons, "m" is the mass measures in grams and "a" is the acceleration that accur due to gravity.
Answer:
(A) 0.3488 rad/sec
(B) 124.246 m
Explanation:
We have given car completes one revolution in 18 sec'
So time period T= 18 sec
Tangential speed v = 43.4 m/sec
(A) Angular velocity is given by 
(B) Tangential velocity is given v = 43.4 m /sec
We know that 

Rising warm air transports thermal energy by ( water vapor).
Water vapor.
<u>Answer:</u> The correct answer is Option 3.
<u>Explanation:</u>
Amplitude of as sound wave is defined as the extent to which the air particles are getting displaced.
Speed of the sound wave is defined as the distance traveled by the sound wave per unit time and is not related to the amplitude of a sound wave.
Wavelength of the sound wave is defined as the difference between two crests or troughs.
Loudness of a sound wave is defined as the size of the vibration which are produced by it. This is closely related to the amplitude of the sound wave.
Pitch is defined as the sensation of the frequency. Higher the frequency, the pitch is also high and vice-versa.
From the above information, the amplitude of a sound wave is most closely related to the sound’s loudness.
Hence, the correct answer is Option 3.
