a sound wave is determined to have a frequency of 1,000 hz and wavelength of 35cm. what is the speed of this wave?

natulia [17]

Answer:

The speed of the sound wave is 350 m $s^{-1}$

Explanation:

Given

Frequency of sound wave = 1000Hz = 1000 $s^{-1}$ (since 1 $s^{-1}$ = 1 Hertz (Hz))

Wavelength of sound wave = 35 cm

Speed of sound wave = ?

All waves have same the relation among frequency, sound and speed which is given by

v=fλ , where

v is the speed

f is frequency

λ is wavelength

Therefore, the speed of sound wave = 1000 $s^{-1}$ x 35 cm

= 35000 cm $s^{-1}$

= 350 m $s^{-1}$

Hence the speed of the sound wave is 350 m $s^{-1}$

HI PLEASE HELP!

butalik [34]

Answer:

Chemical reactions occur slower at lower temperatures and faster at higher temperatures. When you put a glow stick in cold water, the chemical reaction slows down but will last for a longer period of time. When you put a glow stick in hot water, the reaction speeds up but will be over quicker.

Explanation:

(self-explanatory)

I hope this helps, have a nice day.

How much power is necessary to do 50 J of work in 5 seconds

Alex73 [517]

Power = Work / Time

If W = 50 J and T = 5s

P = W/T = 50J/5s = 10 Watts

The model below shows a carbide ion. 8 light grey and 6 dark grey balls sit at the center with 2 concentric black rings around t

azamat

Answer:

This carbide ion change into a neutral carbon atom.

Explanation:

Given that,

Light grey balls = 8

dark grey balls = 6

medium grey balls = 2

Charge on dark grey ball = +1

Charge on light grey ball = 0

Charge on medium grey ball = -1

We need to change this carbide ion to a neutral carbon atom

Using given data

A dark grey ball has one positive charge. It means, it is a proton.

A light grey ball has has zero charge. It means, it is a neutron.

A medium grey ball has one negative charge.It means, it is a electron.

We know that,

The number of proton and number of electron is equal in a neutral atom.

So, No charge is present on the given model of atom.

Therefore, we can say that the atom is neutral.

We know that,

The sum of total number of protons presents in an atom it is called atomic number.

So, The total number of protons is 8, the total number of electrons is 8 and the total number of neutrons is 9 in given atom.

Hence, This carbide ion change into a neutral carbon atom.
