By definition, a convex mirror is a type of an optical mirror wherein its mirror surface bulges at the front. In addition to that, it is contrary to the concave mirror wherein the mirror gets bulged inward. It is furthermore said that we can get a virtual, upright, and smaller image in a convex mirror if it is placed anywhere in the principal axis.
The wavelength of sound wave with frequency 770 Hz and speed of 290 m/s is equal to 0.3767 m
<h3>
Explanation:</h3>
The wave equation determining the relationship between speed, frequency and wavelength of a sound wave is given by:
<u>Speed of sound = Frequency of sound × Wavelength of sound wave</u>
v = n × λ .................................(1)
Given:
v = Speed of sound wave = 290 m/s
n = Frequency of sound = 770 Hz
λ = Wavelength = ?
From (1)
v = n × λ
Rewriting the equation for λ, we get
λ =
Substituting the values of v and n, we get
λ = 
Hence, the wavelength of sound wave is equal to 0.3767 m

Answer:

Explanation:
From the question we are told that
Volume V
Contains N particles
Leaks from a small hole of area A
Generally the equation for Flow rate is given as
Volume Flow Rate 
Mathematically we find the time taken to flow half way which is given by

Therefore the time taken is
