Driving down a quiet street on a summer day with the car windows down, you see a convertible approaching from the opposite direc

Answer:

1 angstrom equals 0.1 nm.

To convert 5000 angstroms: 5000 angstrom = 5000 / 1 × 0.1 nm.

= 500 nm

To express 5000 angstroms in meters: 5000 angstrom = 5000 × 1 × 10^-10.

= 5 × 10^-7 m

Hope this explanation is useful for you.

When air is forced into the open pipe,

L =

where n represents any whole number such as 1,2,3,4, etc., and λ denotes the wavelength of the oscillation

This implies λ=

It is important to note that n=1 corresponds to the fundamental frequency, n=2 corresponds to the first harmonic, and so forth.

Thus, the third harmonic will be for n=4

With L=6m and n=4, solving for λ yields:

λ= =3m

The connection between frequency (f), sound speed (c), and wavelength (λ) is given by:

c=f.λ or f=

≈115 Hz

Answer:

Explanation:

Let us denote the launch angle as .

, , and are complementary angles which means their ranges are identical.

Time of flight is indicated as .
