Which is the relationship between photon energy and the color of light?

Physics

The energy of a photon is given by
E=hf
where 
h is the Planck constant
f is the frequency of the light.

From this formula, we see that the higher the frequency, the greater the energy, and viceversa.

Now let's have a look at the frequencies of the different colors of visible light. Violet is the color with higher frequency, while red is the color with lower frequency. This means that violet photons have the greatest energy, while red photons have the least amount of energy. So, correct answer is 

<span>C. Red photons have the least amount of energy.</span>

A man pushes a stalled car with a force of 100 N. If the acceleration of the car is 0.75 m/s 2 , what is the mass of the car?
shutvik [7]
125 because f=ma so you would use 100=mx0.75

patriot [66]

Answer:

220 V

Explanation:

r_{1} = 20 ohm\\r_{2} = 30ohm\\r_{3} = 60ohm

As the resistors are connected in series,

R_{eq} = r_{1} +r_{2} +r_{3}

= 20 + 30 + 60

= 110 ohms

V = IR

= 2 * 110

= 220 V

Hope it helps

A horizontally oriented pipe has a diameter of 5.8 cm and is filled with water. The pipe draws water from a reservoir that is in
Gnoma [55]

Answer:

v₂ = 97.4 m / s

Explanation:

Let's write the Bernoulli equation

         P₁ + ½ ρ v₁² + ρ g y₁ = P₂ + ½ ρ v₂² + ρ g y₂

Index 1 is for tank and index 2 for exit

We can calculate the pressure in the tank with the equation

        P = F / A

Where the area of ​​a circle is

       A = π r²

E radius is half the diameter

      r = d / 2

      A = π d² / 4

We replace

    P = F 4 / π d²2

    P₁ = 397 4 /π  0.058²

    P₁ = 1.50 10⁵ Pa

The water velocity in the tank is zero because it is at rest (v1 = 0)

The outlet pressure, being open to the atmosphere is P1 = 1.13 105 Pa

Since the pipe is horizontal y₁ = y₂

We replace on the first occasion

   P₁ = P₂ + ½ ρ v₂²

  v₂ = √ (P1-P2) 2 / ρ

  v₂ = √ [(1.50-1.013) 10⁵ 2/1000]

  v₂ = 97.4 m / s

2. A truck is traveling east through mud that is slowing down its speed. With west defined as negative, which of the following i
Lynna [10]

Hi! The answer is C

As west is defined as negative, the trucks velocity is positive, since its travelling east. But its speed (absolute value of velocity) is decreasing, that means that the acceleration is negative.
