Sound travels slower in colder air than it does in warmer air. Make a claim about the effect of air temperature on the speed of

sound.
Physics
1 answer:
vladimir1956 [14]3 years ago
8 0

Answer: The temperature of the air affects the speed of sound in the due to the fact that colder contains air molecules with low kinetic energy. For warm air the kinetic energy of the molecules is high causing them to move in rapid motion. Because of these vibrations and collisions sound waves moves in a faster rate.

Marysya12 [62]

Answer:

1.97*10⁴N .He cannot survive.

Explanation:

The<em> </em><em>Tidal force</em> can be defined as the difference in force between center of  two bodies like center of earth and other bodies.This force stretches  the body too and fro from the center of mass of another body due to the difference in the gravitational force.

The tidal force is responsible for various phenomena like ocean tides,celestial body tearing up.

The tidal force is the effect of massive body gravitationally affecting another body.

The tidal force is the difference between the gravitational force of two bodies and directly proportional to the mass of body affecting another body and inversely proportional to the square of radius of the distance between center and the object.

Here let us consider height of person as 2m and d=1m

  ΔF=\frac{GMm}{(R-d)^{2} } -\frac{GMm}{(R+d)^{2} }

       =GMm[\frac{1}{(R-d)^{2} }-\frac{1}{(R+d)^{2} }]

         =(6.67*10⁻¹¹)(1.99*10³⁰)(1.0)[\frac{1}{(300*10^3-1)^{2} }-\frac{1}{(300*10^3+1)^{2} }}

   ΔF=1.97*10⁴N.

Thus he cannot survive
