Color spectrum

<h2>Further Explanation </h2>

A spectrum is a condition or price that is not limited to a set price but can change indefinitely on a continuum. This word evolved from the Latin word, specter, which means ghosts, but the modern meaning now comes from its use in natural science. A spectrum is a condition or price that is not limited to a set price but can change indefinitely on a continuum. This word evolved from the Latin word, specter, which means ghosts, but the modern meaning now comes from its use in natural science. White is an impression that is captured by the eye and is a combination (superposition of several wavelengths) of various unique wavelengths.

For an easy example, I take the example of white can be produced from a combination of 3 wavelengths of Red Green and Blue or RGB (Red Green Blue).

Spectral is the result of the interaction between electromagnetic energy (EM) and an object. There are objects that have absorption properties (absorption) of high EM and low reflections, otherwise, there are objects that have low absorption and high reflectivity. These reflection and absorption patterns are different for different wavelengths. If it is associated with satellite images, then each object will provide a different EM reflection, so that we are able to distinguish an object from another object (identification). The instrument used to measure the reflectance value of an object is called a spectrometer. On the market there are spectrometers of higher spectral resolution, in addition, there are also spectrometers that can be used underwater (underwater).

the red color is produced from electromagnetic wavelengths/light in the range of 700-630 nanometers.

the green color is produced from electromagnetic/light wavelengths in the range of 560-490 nanometer meters.

the blue color is produced from electromagnetic/light wavelengths in the range of ~ 490-450 nanometer meters.

You throw a basketball and a tennis ball across the classroom so that each ball has the exact same momentum. Explain how this is
Helga [31]

Answer:

It is possible by increasing the speed of the tennis ball by a factor of (Mass of the tennis ball)/(Mass of the basketball)

Explanation:

The momentum of a body = The bod's mass × The body's velocity

Therefore, the momentum of a given mass of an object, such as a tennis ball can be increased by increasing the velocity or speed of the object. Whereby the speed of the ball, v₁, is increased such that the momentum of the basketball and the tennis ball will be the same, is given by the following equation

Mass of the basketball × v₂ = Mass of the tennis ball × v₁

Therefore, v₁/v₂ = (Mass of the tennis ball)/(Mass of the basketball)

Show that the optimal launch angle for a projectile subject to gravity is 45o by carrying out the following steps: 6. Write down
Lorico [155]

Answer:

sin  2θ = 1    θ=45

Explanation:

They ask us to prove that the optimal launch angle is 45º, for this by reviewing the parabolic launch equations we have the scope equation

            R = Vo² sin 2θ / g

Where R is the horizontal range, Vo is the initial velocity, g the acceleration of gravity and θ the launch angle. From this equation we see that the sine function is maximum 2θ = 90 since sin 90 = 1 which implies that θ = 45º; This proves that this is the optimum angle to have the maximum range.

We calculate the distance traveled for different angle

          R = vo² Sin (2 15) /9.8

          R = Vo² 0.051 m

In the table are all values ​​in two ways

Angle (θ)                  distance R (x)

 0                 0                     0

15                 0.051 Vo²        0.5 Vo²/g

30                0.088 vo²        0.866   Vo²/g

45                0.102 Vo²        1   Vo²/g

60                0.088 Vo²      0.866   Vo²/g

75                0.051 vo²        0.5   Vo²/g

90                0                     0

See graphic ( R Vs θ)  in the attached ¡, it can be done with any program, for example EXCEL

Initially a car accelerates at 2 m/s2 for x seconds. The car then travels at a velocity of -6 m/s for x seconds. If the car disp
Luda [366]

Answer:

The time travel is

t=8 s

Explanation:

a= 2 \frac{m}{s^{2} } \\v=-6 \frac{m}{s} \\x=16m

x_{f}=x_{o}+v_{o}*t+\frac{1}{2} *a*t^{2}

x_{f}=0-6*t+\frac{1}{2} *2*t^{2}

t^{2}-6*t-16=0\\ using :\\\frac{-b+/-\sqrt{b^{2}-4*c*a } }{2} \\\frac{-(-6)+/-\sqrt{(-6)^{2}-4*(-16)*(1) } }{2}=\frac{3}{2} +/- \frac{10}{2} \\t_{1} = 2s \\t_{2} = 8s

Check

t_{2}=8s

x_{f}=x_{o}+v_{o}*t+\frac{1}{2} *a*t^{2}

x_{f}=0-6*+\frac{1}{2} *2*8^{2}

x_{f}=-48+64\\x_{f}=16
