Answer:
Wavelength of wave is 2.5 meters
Explanation:
Given that,
Speed of a wave, v = 350 m/s
Frequency of the wave, f = 140 Hz
The formula to find the speed of sound is given by :

The speed of sound is more in higher temperature. At higher temperature, the molecules vibrate with more energy. As a result, sound travel faster in a warm room.
Answer:
As we keep on increasing the radius the value of the gravitation force of attraction decreases and as we decrease the radius the gravitation force increases.
Explanation:
Like the coulombs law of electrostatics, the law of gravitation also depends inversely on the square of the value of r. Therefore, as we keep on increasing the value of r the value of the gravitation force decreases and as we decrease the value of the r the value of gravitation force increases.
Gravitation Force=
Coulombs's Law=
