Answer:
no
Explanation:
White light, which is the visible light, from the sun contains all the rainbow colors; however, ultraviolet is a radiation emitted from the sun and it is nonvisible to humans.
No white light and ultraviolet light are the two types of radiation coming from the sun.
What are solar radiations?The light coming from the sun contains different types of radiation that travel at different wavelengths this radiation is called solar radiation.
Types of solar radiation are visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays.
Due to this visible light, we can see on earth because it has the frequency that our eyes can see.
visible light contains seven colors that are at different wavelengths. So when the diffraction of visible light takes place we can see these seven colors.
Thus white light and ultraviolet light are the two types of radiation coming from the sun.

An book fell from a shelf 1.5 meters from the ground. If it took the book 3 seconds to hit the ground, what was the velocity of the book?
The initial velocity of the book before its hits the ground is 14.2 m/s.
The given parameters;
height of the book above the ground, h = 1.5 mtime of motion of the book, t = 3 secondsThe initial velocity of the book is calculated as follows;
h = ut + ¹/₂gt²
where;
u is the velocity of the book1.5 = 3u + (0.5 x 9.8 x 3²)
1.5 = 3u + 44.1
3u = 1.5 - 44.1
3u = -42.6
[tex]u = \frac{-42.6}{3} \\\\u = -14.2 \ m/s\\\\u = 14.2 \ m/s \ downwards[/tex]
Thus, the initial velocity of the book before its hits the ground is 14.2 m/s.

what is the central idea for stacking rocks vertically to test the effects of forces
Answer:
You can see how forces can stack on one another by comparing the normal force of the bottom most rock to the normal force of the upper most rock.
Explanation:
Say you have 3 rocks all with mass m=3kg
These 3 rocks will all have the gravitational force of -29.4N (multiply 3kg by -9.8m/s^2)
If none of the rocks are stacked, then they all have the same normal force as well (29.4N)
However, stack them, and see how their normal forces change.
m1 will continue to have a normal force of 29.4N
m2 will now have a normal force of 58.8
m3 will now have a normal force of 88.2
Though they all retain the same gravitational force, their normal force changes depending on the forces acting down on them.
Mass 1 have no forces acting downwards other than gravity.
Mass 2 has the force of mass 1 and gravity acting down on it.
Mass 3 has the force of mass 1, mass 2, and gravity acting down on it.

If the mass of an object is 100 and Net force is 400, what would be the Acceleration?
And explain.
Answer:
[tex]4m/s^{2}[/tex]
Explanation:
I'm assuming the units for force and mass are Newtons and kilograms, respectively.
Rearranging Newton's first law (F=m*a) to solve for acceleration:
F=m*a
[tex]a=\frac{F}{m}=\frac{400 N}{100 kg}=4m/s^{2}[/tex]
The acceleration is 4 meters per second squared and was found by rearranging Newton's first law in order to solve for acceleration.
A cart of weight 20 N is accelerated across a level surface at 0.15 m/s?. What net force acts on
the wagon?
The net force that acts on the cart of wagon is calculated as 3N
HOW TO CALCULATE NET FORCE:
The net force of a body can be calculated by multiplying the mass of the body by its acceleration. That is;Force (N) = weight (N) × acceleration (m/s²)According to this question, a weight of 20N accelerated across a level surface at 0.15 m/s². The net force can be calculated as follows:F = 20 × 0.15
F = 3N
Therefore, the net force that acts on the cart of wagon is calculated as 3N.Learn more at: https://brainly.com/question/18109210?referrer=searchResults

What is a longitude?The term Longitude has been refered as the horizontal lines that are the measurement east or west of the prime meridian. Longitude are the imaginary lines that divide the Earth. Longitudes are also called the meridians, which run from north to south pole to pole but they measure the distance east or west.
The hypothesis that the species diversity is greater at lower latitudes than higher latitudes because low-latitude habitats are older would be supported if speciation rates were: the same at high and low latitudes.
Species diversity can be defined as the number of species, present in an area or the ecosystem. More are the number of species, more diverse is the area is. The richness and functionality of an ecosystem is estimated through its diversity.
Therefore,longitudes are the horizontal lines which divide the Earth.
