V2 = V1 + gt
V2 = 0 + 9.8*3.6 = 35.28 m/s
The sound wave travels faster at higher temperatures and slower at lower temperatures.
<h3>What will happen to the velocity of the wave if the temperature decreases?</h3>
At a lower temperature, particles of the medium are moving more slowly as compared to higher temperature. Due to lower temperature, longer time is required to transfer the energy of the sound waves.
So we can conclude that sound travels faster at higher temperatures and slower at lower temperatures.

Answer:
2
Explanation:
since the second object was in it stationary, it velocity is 0 m/s
Answer:
22.66Nm²/C
Explanation:
Flux through an electric field is expressed as ϕ = EAcosθ
When a piece of paper is held with one face perpendicular to a uniform electric field the flux through it is 25N.m^2/c. If the paper is turned 25 degree with respect to the field the flux through it can be calculated using the formula.
From the formula above where:
EA = 25N.m^2/C
θ = 25°
ϕ = 25cos 25°
ϕ = 22.66Nm²/C
