vagabundo [1.1K]

Answer:

A )

Explanation:

This change in frequency observation occur due to doppler effect

if the wave source moves,In the time between one wave peak being emitted and the next, the source will have moved so that the shells will no longer be concentric. The wavefronts will get closer together in front of the source as it travels and will be further apart behind it.  (see the graph)

when the person standing still in front of the ambulance, he will observe a <em>higher frequency </em>than before as the source travels towards them.

f_(observed)=\frac{V_(wave)}{V_(wave)-V_(source)} *f_(original)

The pitch we hear depends on the frequency of the sound wave.

A high frequency corresponds to a high pitch

as we hear a higher frequency , it makes the <em>pitch higher</em> too

Hello....I need help with this question.
musickatia [10]

Answer:

3.2 m/s²

Explanation:

Acceleration can be calculated as:

v = u + at (where v is final velocity, u is initial velocity, a is acceleration and t is time)

25 m/s  = 9 m/s  + a(5 s)  (a is unknown)

16 m/s  = a(5 s)

a = 3.2 m/s²

We assume that this is a uniform acceleration (meaning that the velocity increases at an equal rate for those 5 seconds).

~Hello There!~

An atom can be identified by its elemental number. The atomic number is equal to the number of protons located in the nucleus. The protons are positively charged particles. Each ion has a specific place in an atom. Electrons are located outside of the nucleus. The electrons are arranged by the electron shells in the atom(?). Each element has electrons that can only hold a certain number of electrons for each energy level. Electrons have many shells - the electron cloud/shell with the most energy is known as the valence(?). The valence electrons are located at the outermost shell of the electron cloud.

Hope This Helps You!

Good Luck :)

Have A Great Day ^_^
