The speed of sound depends on the medium in which it is transported.

Sound travels fastest through solids, slower through liquids and slowest through gases.

So it will travel slowest through water at 55 degrees

Answer:

water at 55°C

Explanation:

Sound is a mechanical wave, which travels through a medium by the vibrations of the particles in the medium, which collide with each other, allowing the sound wave to propagate through the medium.

Based on this explanation, we can understand two facts:

1) sound waves travel faster in solids than in liquids. This is because the particles inside a solid are much closer together than in a liquid, so the wave can be transferred faster because there are more collisions between the particles of the solid

2) The speed of a sound wave increases as the temperature increases. This is because at higher temperatures, particles move faster, so the wave can be transmitted faster.

Therefore, #1 tells us that sound travels slower in water than in ice, while #2 tells us that sound travels slower at 55°C than at 75°C . Therefore, sound travels slowest in water at 55°C .

Margy is trying to improve her cardio endurance by performing an exercise in which she alternates walking and running 100.0 m ea

Kipish [7]

Answer:

6.5 m/s

Explanation:

We are given that

Distance, s=100 m

Initial speed, u=1.4 m/s

Acceleration, $a=0.20 m/s^2$

We have to find the final velocity at the end of the 100.0 m.

We know that

$v^2-u^2=2as$

Using the formula

$v^2-(1.4)^2=2\times 0.20\times 100$

$v^2-1.96=40$

$v^2=40+1.96$

$v^2=41.96$

$v=\sqrt{41.96}$

$v=6.5 m/s$

Hence, her final velocity at the end of the 100.0 m=6.5 m/s

Parallel light waves hit the surface of a still lake and reflect in the same direction. Which interaction of light and matter do

vampirchik [111]

Answer:

Regular reflection

Explanation:

- Reflection is the phenomenon that occurs when a light wave hits the interface between two different mediums and it bounces off back into the same medium. The angle of reflection (measured between the reflected ray and the perpendicular to the interface) is equal to the angle of incidence (measured between the incident ray and the perpendicular to the interface).

There are two different types of reflection:

- Regular reflection: this occurs when the interface between the two mediums is smooth (such as in the case of the still lake), so all the parallel light waves (which have same angle of incidence) are reflected exactly with the same angle of reflection (so, they come out all with same direction)

- Diffuse reflection: this occurs when the interface between the two mediums is not smooth, so each light ray is reflected with a different angle because it hits the interface with a different angle of incidence.

Therefore, in the case of the still lake, the correct answer is regular reflection.
