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.

Energy produced by nuclear fusion is ?
pentagon [3]
<h3><u>Answer;</u></h3>

<em>D. Produces no wastes</em>

<h3><u>Explanation;</u></h3>
  • <em><u>Nuclear fusion are nuclear reactions in which two or more atomic nuclei fuse or join to generate different atomic nuclei together with subatomic particles, such as protons or neutrons. </u></em>
  • Additionally,<em><u> nuclear fusion reactions yields lots energy.</u></em> The energy produced is usually more than the energy consumed by the reaction.
  • <em><u>Fusion power  is a form of power generation in which energy generated using fusion reactions is used to produce heat that is used in generation of electricity.</u></em> Energy from nuclear fusion reactions is not coupled by production of wastes.

A satellite is put in a circular orbit about Earth with a radius equal to 35% of the radius of the Moon's orbit. What is its per
Debora [2.8K]

Answer:

0.21 lunar month

Explanation:

the radius of moon = r₁

time period of the moon = T₁ = 1 lunar month

The radius of the satellite = 0.35 r₁

Time period of satellite

The relation between time period and radius

              T\ \alpha\ \sqrt{r^3}

now,

              \dfrac{T_2}{T_1}=\dfrac{\sqrt{r_2^3}}{\sqrt{r_1^3}}

              \dfrac{T_2}{T_1}=\dfrac{\sqrt{0.35^3r_1^3}}{\sqrt{r_1^3}}

              \dfrac{T_2}{1}=\sqrt{0.35^3}

                              T₂ = 0.21 lunar month

hence, the time period of revolution of satellite is equal to 0.21 lunar month

Jack and Jill are maneuvering a 3300 kg boat near a dock. Initially the boat's position is &lt; 2, 0, 3 &gt; m and its speed is
Paraphin [41]

Answer:

The workdone by Jack is  W_{jack} = -1050J

The workdone by Jill is  W_{Jill} = 0J

The final velocity is  v = 1.36 m/s

Explanation:

From the question we are given that

          The mass of the boat is m_b = 3300kg

          The initial position of the boat is   P_i  = (2 \r  i  + 0 \r j + 3\r k)m

           The Final position of the boat is  P_f = (4\r i + 0 \r j + 2\r k )\ m

           The Force exerted by Jack \r F = (-420\r i + 0 \r j + 210\r k) \ N

             The Force exerted by Jill  \r F_{Jill} =(180 \r i + 0\r j + 360\r k)

Now to obtain the displacement made we are to subtract the final position from the initial position

                                 \r P = P_f - P_i

                                    = (4\r i + 0\r j + 2 \r k) - (2\r i + 0\r j + 3\r k  )

                                     = (2\r i + 0\r j -\r k )m

Now that we have obtained the displacement we can obtain the Workdone

  which is mathematically represented as

                                                   W =\r  F * \r P

 The amount of workdone by jack would be

                                               W_{jack} =\r  F * \r P

                                                 = [(-420\r i +0\r j +210\r k)(2\r  i + 0\r j - \r k)]

                                                 = (-420) (2) + (210)(-1)

                                                = -840 - 210

                                               =-1050J

  The amount of workdone by Jill would be

                                                 W_{Jill} =\r  F * \r P

                                                        = [(180 \r i + 0\r j + 360\r k)(2\r i +0\r j -\r k)]

                                                       = (180 )(2) +(360)(-1)

                                                       =0J

According to work energy theorem the Workdone is equal to the kinetic energy of the boat

              W = K.E = \frac{1}{2} m *[v^2 - (1.1)^2]

             -1050  = 0.5*3300 [*v^2- (1.1)^2]

            -1050 = 1650 [v^2 -1.21]

               0.6363 = v^2 -1.21

                   v^2 = 0.6363+1.21

                    v^2 =1.846

                    v = 1.36\ m/s

a centrifugal force ride, similar to the gravitron, spin at a speed of 22 revolutions per minute. if the diameter of the ride is
Margarita [4]

The linear speed of the passengers in kilometres/hour is 1.152 km/h.

The centrifugal force ride spins at a speed of 22 rev/min. The diameter of the ride is 14 meters.

We know,

Diameter = 2(Radius)

Radius = 14/2m

Radius = 7m

Radius of the centrifugal ride is 7m.

Also,

1 rev = 2π radians

22 rev = 44π radian

Angular Speed in rad/s = 44π/60

The relationship between the angular speed W and the linear speed V is given as,

V = W/R

R is the radius of the circle,

Now, putting the values,

V = 44π/(60×7)

V = 0.32 m/s.

So, the linear speed of the passengers is 0.32 m/s.

It is know, for conversion from m/s to km/h

1 m/s = 3600/1000 km/h

So, 0.32m/s in km/h is,

0.32m/s = 0.32 × 3600/1000

Linear speed in km/h is 1.152km/h.

\If we could put all the asteroids together, their total mass would be ________. If we could put all the asteroids together, the
timofeeve [1]

Answer:

much less than the mass of any terrestrial planet

Explanation:

According to www.wikipidia.com

The mass of all the objects of the asteroid belt, lying between the orbits of Mars and Jupiter, is estimated to be about 2.8–3.2×1021 kg, or about 4% of the mass of the Moon. Of this, Ceres comprises 0.95×1021 kg, a third of the total.

While mass of terrestrial planet is

5.97 x 1024 kg (which works out to 5,970,000,000,000 trillion metric tons) Earth is the most massive of all the terrestrial planets (www.universetoday.com)

By doing the calculation, mass of all the asteroid are much less than the mass of any terrestrial planet
