If a galaxy is located 200 million light years from Earth, what can you conclude about
the light from that galaxy?
A. The light will travel a total of 200 million kilometers to reach Earth.
B. The light will travel 200 million kilometers per second to reach Earth.
C. The light will travel a total of 300,000 kilometers to reach Earth.
D. The light will take 200 million years to reach Earth.
please help :(
Answer:
D
Explanation:
It's quite simple actually, you see, what light years basically means is how many years light takes to travel from point a to point b. So here it says that a galaxy is 200 million light years away. So since that light is 200 million years away, it would take 200 million years until that light reaches us.
Which shows increasing entropy?
mowing a lawn
folding clothes
falling leaves
washing dishes
Answer:
mowing a lawn
Explanation:
Entropy is the degree of disorderliness of a system. As a body moves from a more ordered state to a less ordered one, the entropy of the system increases.
Mowing a lawn is a typical example of increasing entropy. When a lawn is being mowed, the grasses becomes disordered without any fixed orientation. Folding a clothe is trying to bring orderliness to the clothe patterning. Washing dishes will make one arrange them in an ordered way. Falling leaves brings leaves together.Answer:
Falling leaves!

How is the 3rd law different from the 1st and 2nd laws?
Answer:
In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

The Electron Cloud Model shows shaded regions of probabilty where the electons most likely are at a given point in time. True False
Answer:
True
Explanation:
The statement is true because According to Schrödinger it's not possible to get the exact position of where an electron is located. However, he showed from an equation that we can at determine the most likely area where an electron will be and he said they are most likely to be in the most dense area of the clouds.
Answer:
it is true
Explanation:
A force off 700 newtons is applied to a 600 kg bowling ball. What is the acceleration of the bowling ball once the force is applied?
Answer:
1.17 m/s²Explanation:
The acceleration of an object given it's mass and the force acting on it can be found by using the formula
[tex]a = \frac{f}{m} \\ [/tex]
f is the force
m is the mass
From the question we have
[tex]a = \frac{700}{600} = \frac{7}{6} \\ = 1.1666666...[/tex]
We have the final answer as

The sun has a mass of 1.99 x 10-30 kg. Saturn has a
mass of 5.68 x 10^26 kg. The distance between the sun
and Saturn is 1.43 x 10^12 m. Calculate the gravitational
force between the sun and Saturn.
Answer: The gravitational force between the sun and Saturn is [tex]3.69\times 10^{22}N[/tex]
Explanation:
[tex]F=\frac{Gm_1m_2}{r^2}[/tex]
where F = gravitational force = ?
G = gravitational constant = [tex]6.674\times 10^{-11} Nm^2kg^{-2}[/tex]
[tex]m_1[/tex] = mass of sun = [tex]1.99\times 10^{30}kg[/tex]
[tex]m_2[/tex] = mass of saturn = [tex]5.68\times 10^{26}kg[/tex]
r = distance between sun and saturn = [tex]1.43\times 10^{12}m[/tex]
[tex]F=\frac{6.674\times 10^{-11}Nm^2kg^{-2}\times 1.99\times 10^{30}kg\times 5.68\times 10^{26}kg}{(1.43\times 10^{12}m)^2}[/tex]
[tex]F=3.69\times 10^{-90}N[/tex]
Thus the gravitational force between the sun and Saturn is [tex]3.69\times 10^{22}N[/tex]
what is projectile motion
[tex]\mathsf{what ~is~ a ~projectile ~motion?? }[/tex]
Answer:[tex]\large \underbrace{ \underline{ \sf projectile \: motion }}[/tex]
Projectile motion is when an object moves in a bilaterally symmetrical, parabolic path. The path that the object follows is called its trajectory. Projectile motion only occurs when there is one force applied at the beginning, after which the only influence on the trajectory is that of gravity.Some examples of Projectile Motion are Football, A baseball, A cricket ball, or any other object. The projectile motion is always in the form of a parabola which is represented as:[tex]\dashrightarrow\bold{y = ax + bx {}^{2}}[/tex]In the picture to the right, find the angle at which
the box is pulled if the work done is 50J
Answer:
42 °
Explanation:
From the question given above, the following data were obtained:
Force (F) = 45 N
Workdone (Wd) = 50 J
Distance (d) = 1.5 m
Angle (θ) =.?
Angle at which the box is pulled can be obtained as:
Wd = Fd × Cos θ
50 = 45 × 1.5 × Cos θ
50 = 67.5 × Cos θ
Divide both side by 67.5
Cos θ = 50 / 67.5
Cos θ = 0.7407
Take the inverse of Cos
θ = Cos¯¹ 0.7407
θ = 42.2 ≈ 42 °
Thus, the angle at which the box is pulled is approximately 42 °.

TRUE or FALSE?If you are an astronaut slowly drifting away from the space station, you might be able to drift back to the station by throwing a 5-kg tool rapidly in the direction that you are traveling (away from the station).
Answer:
yes every action as an equal and and opposite reaction. if you throw a tool then it will give you a reaction and you will move back.
Explanation:
According to Newton's third law of motion, when two bodies interact between them, appear equal forces and opposite senses in each of them.
To understand it better:
Each time a body or object exerts a force on a second body or object, it (the second body) will exert a force of equal magnitude but in the opposite direction on the first.
So, if you as an astronaut in the described situation throw your tool in the direction that you are traveling (in the opposite direction of the space station), according to Newton's third law, you will be automatically moving towards the station

If the astronaut in the video wanted to move upward, in which direction should he throw the object? Why?
1.He should throw the object upward because according to Newton’s third law, the object will then exert a force on him in the same direction (i.e., upward).
2.He should throw the object upward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i.e., downward).
3.He should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i.e., upward).
4.He should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the same direction (i.e., downward).
Answer:
3.
Explanation:
If the astronaut in the video wanted to move upward, he should throw the object downward because according to Newton’s third law, the object will then exert a force on him in the opposite direction (i.e., upward). hence, option (3) is correct.
What is Newton's third law of motion?Newton's Third Law states that if object A exerts a force on object B, then object B must apply a force to object A that is equal in magnitude and directed in the opposite direction.
This law represents a specific symmetry in nature: forces always exist in pairs, and no body can exert a force without also being subjected to one.
Hence, if the astronaut in the video wanted to move upward, he should throw the object downward and the object will then exert a force on him in the opposite direction (i.e., upward).

The talk test is about the easiest way that one can monitor intensity as they exercise. Because the only thing needed here is the ability to talk and to breathe.
The intensity lies on if one can talk and breathe at the same time. The harder one exercises, the more breathless they become and they find it difficult to talk.

Answer:
63.4 °C
Explanation:
If we assume the "fixed points" are 0 °C and 100 °C, then the thermometer reading as a function of actual temperature can be described by a linear equation that must have (0, -0.5) and (100, 106) as solutions. We can use these points in the 2-point form of the equation for a line:
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (106 -(-0.5))/(100 -0)(x -0) -0.5
y = 106.5x -0.5
Then, for x = 60, the thermometer reading is expected to be ...
y = 106.5×60 -0.5 = 63.4 . . . °C
