Physics
1 answer:
Rasek [7]3 years ago

Answer:

460.8 m/s

Explanation:

The equation that relates fundamental frequency, wavelength and speed of a standing wave on a string is

f=\frac{v}{2L}

where

f is the frequency

v is the speed of the wave

L is the length of the string

in this problem, we have

f = 256 Hz is the frequency

L = 0.90 m is the length of the string

Therefore, re-arranging the equation we can find the speed of the wave:

v=2Lf=2(0.90 m)(256 Hz)=460.8 m/s

What part do tiny, solid particles in the atmosphere play in cloud formation?
Margarita [4]
Well,

The tiny, solid particles you find in the atmosphere serve as cloud condensation nuclei.

You see, in order for water to condense, the water must have a direct object, grammatically speaking.

Your answer: Tiny, solid particles in the atmosphere play a role in cloud formation by providing the object upon which water may condense to form clouds.

Calculate the electric field associated to an electric dipole for two charges separated 10-8 m with a dipole moment of 10-33 C m
Alex Ar [27]

Answer:

18 N/C

Explanation:

Given that:

Electric field constant, k = 9*10^9 N/c

Distance, r = 10^-8 m

Dipole moment, p = 10^-33

Using the relation for electric field due to dipole :

E = [2KP / r³]

E = (2 * (9*10^9) * 10^-33) ÷ (10^-8)^3

E = (18 * 10^9 * 10^-33) ÷ 10^-24

E = [18 * 10^(9-33)] ÷ 10^-24

E = (18 * 10^-24) / 10^-24

E = 18 * 10^-24+24

E = 18 * 10^0

E = 18 N/C
