Answer:
The answer is C (Higher energy levels)
Explanation:
Because it's C
Answer:
The frequency of the sound note as heard = 429 Hz
Explanation:
The frequency of sound waves as heard from a distance for a sound wave coming towards one at v₀ m/s and whose real frequency is f₀ is given by
+f = f₀/[1 - (v₀/v)]
+f = frequency of sound as heard from the distance away = ?
f₀ = real frequency of sound = 401 Hz
v₀ = velocity at which the sound source is moving towards the reference point = 23.0 m/s
v = velocity of sound waves = 343 m/s
+f = 401/[1 - (23/343)]
+f = 429 Hz
The correct answer is C, right-side up and smaller.
It is the most common example of spherical mirrors. The inside of the spoon acts like a concave mirror and the back side of it like a convex mirror.
A convex mirror always forms a real and diminished image. That is, the image formed is erect or right-side up and smaller in size. Therefore, Lin Yao should describe her reflection on the back side of the mirror to be right-side up and smaller.
