Answer:

Option (B)

Explanation:

Light is a form of electro-magnetic waves. This light wave has distinct range of wavelength that allows it to form different colors of light. This means that the color of the light produces depending on the amount of wavelength it comprises.

The visible light ranges from Violet to Red, and this is observed as different colors when each of these electromagnetic waves strikes our eyes at a certain angle. The violet light has the shortest wavelength of about 410 nm, where the red light has the highest wavelength of about 650 nm.

Thus, the correct answer is option (B).

Answer:

option (B)

Explanation:

Light waves are electromagnetic waves which can be seen by our eye.

The white light contains seven colours of light which are given below:

Violet

Indigo

Blue

Green

Yellow

Orange

Red

This is the order of increasing wavelength and the decreasing frequency.

So, the wavelength of blue light and the red light is different.

An electron and a proton, starting from rest, are accelerated through an electric potential difference of the same magnitude. in
Yakvenalex [24]
The charges are the same in absolute value, so the change of potential energy is the same. That means that the change in kinetic energy is also the same. Then:

1 = Ke/Kp = m_e *v_e^2 / m_p * v_p^2, or

v_e/v_p = sqrt( m_p/m_e),

So the speed of the electron will be sqrt( m_p/m_e) times greater than the speed of the proton

A U.S. Department of Energy report estimates that over 100 billion kWh/year can be saved in the United States by various energy-
I am Lyosha [343]

Answer:

(a). 12 plants

(b). 3171 $

Explanation:

(a)first convert units of 100 billion kWh/year into Watts(W)

also convert the units of 1000 MW into Watts(W)

1 billion = 10^9

1 year = 365*24 = 8760 hrs

so

100 billion kWh/year = 1\frac{100*(10^9)*(10^3)}{8760}

                                  = 1.142*10^{10}W

1000 MW                  = 1000*10^{6} = 10^{9}W

no. of plants = \frac{1.14155*10^{10} }{10^9} = 11.4

So 12 plants required        

(b)

savings = unit price*total units

             = 0.1 * 1.142*10^{10}( \frac{1}{1000*3600} )

             = 3170.9 =3171 $

3. The following sound waves have what velocity? (convert cm into m in your calculations.)
mestny [16]

The sound waves with the frequency 20 Hz, 200 Hz, 2,000 Hz, and 20,000 Hz have a velocity of 344 m/s.

<h3>What are sound waves?</h3>

A sound wave is a sample resulting from the motion of strength traveling thru a medium (inclusive of air, water, or every other liquid or stable matter) because it propagates from the supply of the sound. Sound waves are created and convey strain waves, for example, a cellphone.

The frequency can be given as:

Frequency = Velocity/ Wavelength

Velocity = Frequency * Wavelength

The velocity of the following sound waves is given as:

  • Frequency = 20 Hz

Wavelength = 17.2 m

Velocity = 20 * 17.2 m/s

Velocity = 344 m/s

  • Frequency = 200 Hz

Wavelength = 1.72 m

Velocity = 200 * 1.72 m

Velocity = 344 m/s

  • Frequency = 2,000 Hz

Wavelength = 17.2 cm = 0.172 m

Velocity = 2,000 * 0.172 m/s

Velocity = 344 m/s

  • Frequency = 20,000 Hz

Wavelength = 1.72 cm = 0.0172 m

Velocity = 20,000 * 0.0172 m/s

Velocity = 344 m/s

Which is the direction of in stantaneous velocity for angular path
Alexandra [31]

<em>Answer:</em>

<em>Right hand rule</em>

<em>Explanation:</em>

<em>The rule by which the direction of a rotational vector can be found: take your right hand, curl your fingers and stick your thumb straight up. If you let the curl of your fingers follow the path of the rotating particle or body, your thumb will point in the direction of the angular velocity of the body.</em>
