white light such as that from the sun is actually only ultraviolet light.?
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.

Given w= 4+,- 0.02 A=2.0+,-0.2 and 3.0+,-0.6 what is the value of w\ A y square
Explanation:
w = (4.52 ± 0.02) cm, x = ( 2.0 ± 0.2) cm, y = (3.0 ± 0.6) cm. Find z = x + y - w and its uncertainty.
z = x + y - w = 2.0 + 3.0 - 4.5 = 0.5 cm
Dz = Dx + Dy + Dw = 0.2 + 0.6 + 0.02 = 0.82 rounding to 0.8 cm
So z = (0.5 ± 0.8) cm
Solution with standard deviations, Eq. 1b, Dz = 0.633 cm
z = (0.5 ± 0.6) cm
Notice that we round the uncertainty to one significant figure and round the answer to match.
When you describe a liquid as thick, are you saying that it has a high or a low viscosity?
The liquid with greater thickness will be more viscous since it flow speed is lower. Therefore, the more thick liquids is more viscous and flow slowly.
What is viscosity ?Viscosity of a liquid is the resistance to its flow. Viscosity depends on the density and thickness of the liquid. The more thicker the liquid the more viscous it will be.
Less thick liquids will flow fastly. For example water is a less viscous liquid as we see it flow so quickly. Whereas, honey, oil, etc are more viscous and the mobility of their liquid particles are resisted by viscosity.
The more viscous liquids generally has higher specific heat capacity as in the case of water and oil. The particle - particle attractive force is higher in highly viscous liquids.

how did the discovery of eris force astronomers to reconsider the definition of planet?
Answer:
Explanation:
They had demoted Pluto on the basis of the discovery of Eris. They also discovered that Eris had a moon. It was thought to be much bigger than Pluto. That turned out not to be true. So having accepted Eris as a planet, they had to consider carefully what to do about Pluto. It has a gravitational constant of 0.82 m/s^2 which is 8.4% of that of our gravitational pull. and slightly more than Pluto.
Later data showed that these two objects in space were more like twins and that's what shook up the definition of a planet. You can't demote one and not the other.

The answer is static friction. This is the friction that involves objects that do not move.
Explanation:
Friction is a force which opposes the motion of one object moving relative to another. static friction and kinetic friction are the two type of friction.
Static friction is that type of friction which keeps an object at rest. Force must be applied greater than static friction to move an object. Therefore it is the static friction which helps the pile of rocks from falling apart.

why is the saturated lapse rate less than the dry adiabatic lapse rate?
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
Lifting a saturated package causes it to expand and cool, resulting in vapour condensation. Condensation will release latent heat, partially counteracting the cooling. As a result, a saturated parcel's adiabatic lapse rate is smaller than an unsaturated parcel's.
Because moist air ascending condenses off its water vapour, the moist adiabatic lapse rate is lower than the dry adiabatic lapse rate (once saturation is attained). The air is considered to be saturated when the dew point temperature and air temperature are identical.

A cannon is fired with an initial horizontal velocity of 20 m/s and initial vertical velocity of 25 m/s. After 3s in the air, the canon hits it’s target. How far away(in meters) was the canon from its target? Answer:_____m
Answer:
60 m
Explanation:
After 3 seconds of travel at 20 m/s, the projectile is 3·20 = 60 meters horizontally from the cannon.
__
The vertical height after 3 seconds is 0.9 m, so the straight-line distance from cannon to target is √(60^2 +0.9^2) ≈ 60.007 meters.

Newton’s third law states that for every action there is an equal and opposite reaction. So if Jane pushed with a force of 15N, 15N would be pushed back at her. Hope this helps! :)
Explain how the basic unit are combined to give the derived units of force, velocity, pressure and work
Velocity:
Velocity is change in displacement with respect to time:
[tex]\frac{\Delta x}{\Delta t}[/tex]
Analysing the units, meters (displacement) and seconds (time) are basic units:
[tex]\frac{m}{s}[/tex]
Therefore the unit of velocity is m/s
Force:
Newton's second law of motion:
[tex]F = ma[/tex]
Kilogram (mass) is a basic unit, and accelerations unit can be found using the equation:
[tex]a=\frac{\Delta v}{\Delta t}[/tex]
Analysing the units:
[tex]\frac{\frac{m}{s}}{s}=\frac{m}{s^2}[/tex]
Therefore, the unit of force is:
[tex]kg\frac{m}{s^2}[/tex]
Pressure:
Pressure is given by the equation:
[tex]P=\frac{F}{S}[/tex] where S is area of effect, F is force
Area for a basic rectangle (geometric shape is arbitrary for dimensional analysis) is found by multiplying two lengths:
[tex][l^2]=m^2[/tex], the unit of area
Dividing the aforementioned unit of force by the unit of area:
[tex]\frac{kg\frac{m}{s^2}}{m^2}=\frac{kg}{ms^2}[/tex], the unit of pressure
Work:
Work is given by the equation:
[tex]W=\vec{F}\cdot \vec{x}[/tex], (dot product may be assumed as normal multiplication for the purposes of unit analysis)
Knowing displacement's (x) unit is m:
[tex][W]=\frac{kgm}{s^2}m=\frac{kgm^2}{s^2}[/tex], the unit of work.

A 63 kg boy and sled are pulled along level ground with a force of 577 N. The boy and sled
are moving at a constant velocity of 2.4 m/s. What is the size of the frictional force?
Answer:
The size of the frictional force is 577 N.
Explanation:
What is frictional force?Frictional forces are exerted every time you have two surfaces sliding across one another. Friction depends on:
how rougher are the surfaces on contact;how harder you push one surface to the other.There are two types of friction:
static friction [tex]f_s[/tex];dynamic (sliding) friction [tex]f_d[/tex].Now let's attack the problem:
First, you have to write the data down:
[tex]\bullet \quad m= 63\,kg\\\\\bullet \quad F= 577\,N\\\\\bullet \quad v= 2.4\,m/s[/tex]
If the boy and the sled moves on constant velocity, Newton's First Law Of Motion states that the net force acting on them must be zero:
[tex]F_{net}=0[/tex]
Applying Newton's Second Law Of Motion, we get:
[tex]F-f_d=0[/tex]
which means that:
[tex]F=f_d[/tex]
In other words, the dynamic frictional force equals the force that moves the boy and sled. So we may write:
[tex]\boxed{f_d=577\,N}[/tex]
Conclusion: the size of the (dynamic) frictional force is 577 N.

Describe the relationship between the state of matter of water (gas, liquid, solid) and the motion of the water molecules.
Answer:
ok
Explanation:
solid- molecules are close together and vibrating
liquid - molecules are loser, faster moving and take the shape of its container
gas- fast moving molecules and take whatever shape they want (like a room or the air outside)
Explanation:
Solids: The inter-molecular attraction force is the highest and the inter-molecular distance is the least. Solids have definite shape and volume.
Liquids: The inter-molecular attraction force is less than that of solids and the inter-molecular distance is more than solids. Liquids have definite volume but no definite shape.
Gases: The inter-molecular attraction force is the least and the inter-molecular distance is the highest. Gases have no definite shape or volume.

What is ankle sprain?A sprain takes place when your ankle is compelled to move out of its regular place, causing one or more of the ligaments in your ankle to stretch, partially tear, or completely tear.
A sprained ankle can be caused by a fall that causes your ankle to twist. Landing on your foot awkwardly after jumping or pivoting.
You should avoid strenuous exercises, such as running, until the pain and swelling have subsided, but you should keep moving so that the muscles and ankle do not stiffen. Once your ankle is less painful, begin some gentle exercises.
As she is having ankle sprain, and she is planning to take pain killers and start to work out, this can cause her even more problem as she will not feel any pain.
Thus, the correct option is A.
