All waves change speed when they enter a new medium, but they don't always bend. When does bending occur?

Answers

Bending occurs when one side of the wave enters the new medium before the other side of the wave. ... The bending occurs because the two sides of the wave are traveling at different speeds.

The Doppler Effect is caused by which of the following?

Select all that apply…

A - motion of the source

B - the type of wave

C - original frequency of the source

D - motion of the observer

E - type of medium the wave is in

Answers

Answer:

the type of wave

Explanation:

Description: Doppler Effect works on both light and sound objects. For instance, when a sound object moves towards you, the frequency of the sound waves increases, leading to a higher pitch. Conversely, if it moves away from you, the frequency of the sound waves decreases and the pitch comes down.

Explanation:

F=ma

Given that,

F = 4106N

and a = 4.3m/s²

By rearranging the equation,

m = F÷a

m = 4106 ÷ 4.3

m = 954.88kg

A 10,000-watt radio station transmits at 535 kHz.


Calculate the energy of a single photon at the transmitted frequency.


A)3.55 × 10-28 J/photon

B)3.55 × 10-31 J/photon

C)6.63 × 10-30 J/photon

Answers

Answer: A

Explanation: E=hv, E-energy, h-Planck constant, v-frequency
E=6.63×10^(-34)*535*10^3=3.55*10^(-28) (J) Photon energydoesn't depend on the power of radio station

The energy of a single photon at the transmitted frequency is

A)3.55 × 10^(-28)J/photon

What is the energy of a single photon?

Energy of photon can be rewritten as

E=hv,

Where, h is planck's constant  

λ is the wavelength of photon  

Where f is the frequency of photon  

Thus, the energy of a single photon at the transmitted frequency obtained by using the formula, Energy (E) is equal to Planck's constant (h) times the frequency.

E=6.63×10^(-34)× 535×10^3

E =3.55 × 10^(-28) (J)

A wave has a frequency of 60 Hz and a wavelength of 1.7 meters. What is the speed of this wave? equation, substitution

Answers

Answer:

v = 102 m/s

Explanation:

Given that,

The frequency of a wave, f = 60 Hz

Wavelength = 1.7 m

We need to find the speed of this wave. The formula for the speed of a wave is given by

[tex]v=f\lambda[/tex]

Substitute all the values,

[tex]v=60\times 1.7\\\\v=102\ m/s[/tex]

So, the speed of the wave is equal to 102 m/s.

A young boy swings a yo-yo horizontally above his head so that the yo-yo has a centripetal acceleration of 200 m/s^2. If the yo-up’s string is 0.33 m long, what is the yo-up’s tangential speed?

Answers

Answer:

v = 8.12 m/s

Explanation:

The centripetal acceleration of the yo-yo is given by the following formula:

[tex]a_c = \frac{v^2}{r}\\\\v^2 = a_cr\\v = \sqrt{a_cr}[/tex]

where,

v = tangential speed = ?

ac = centripetal acceleration = 200 m/s²

r = radius = length of string = 0.33 m

Therefore, using the given values in the formula, we get:

[tex]v = \sqrt{(200\ m/^2)(0.33\ m)}[/tex]

v = 8.12 m/s

SE UM CORPO ELETRICAMENTE NEUTRO É CARREGADO COM PROTONS, entao afirmamos; a) fica carregado negativamente b) fica carregado só com cargas positivas c) fica carregado positivamente d) fica com excesso de eletrons e) continua eletricamente neutro

Answers

Answer:

c) It gets positively charged

Explanation:

If an electrically neutral body is loaded with protons so it gets positively charged because proton has positive charge. When the protons is added to the neutral body, it can't remain neutral because the quantity of positive charges increases in the nucleus and it gets positively charged while on the other hand, the atom from which protons are taken will acquire negative charge due to presence of more number of electrons and we know that electrons has negative charge.

Explanation:

22. The energy of an electromagnetic wave and it's frequency are related by the following equation:

E = hf

Where:

E => is the energy

h => is the Planck's constant

f => is the frequency

From the equation i.e E = hf, we can conclude that the energy of a wave is directly proportional to it's frequency. This implies that an increase in the frequency of the wave will lead to an increase in the energy of the wave and also, a decrease in the frequency will lead to a decrease in the energy of the wave.
