PLEASE HELP I WILL GIVE BRAINLIEST JUST PLEASE PLEASE HELP
Answer:
planets move in elliptical orbit.
Explanation:
this is because planets are formed closer to the sun while the comets are formed further.
The Sun is home to 99.85% of all stuff in the Solar System.All objects in our solar system orbit the Sun.The movement of planets is elliptical in nature.
What is solar system?Our solar system consists of the Sun, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, as well as the planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
It consists of the planets' satellites, as well as numerous comets, asteroids, and meteoroids, as well as the interplanetary medium. The Sun is home to 99.85% of all stuff in the Solar System.
The movement of planets is elliptical due to the fact that planets are present closer to the sun while the comets are present farther away from the sun as compared to the planets.
Hence the movement of planets is elliptical in nature.

A cruise ship travels across a river at 25 meters per minute. If the river is 6200 meters wide, how long
does it take the ship to reach the other side.
Answer:
248 minutes
Explanation:
6200/25=248
This means there is 248 25s in 6200
which means it will take 248 minutes to travel through the river
Also here's a neat trick:
The units for speed is meters/minute
The units for distance is meters
Dividing distance by speed will cancel out the meters and leave only the speed.
For this problem, you will only be concerned with the geometric aspects of thin-film interference, so ignore phase shifts caused by reflection from a medium with higher index of refraction. (Because of the structure of a butterfly's wings, such phase shifts do not contribute much to what you actually see when you look at the butterfly.) Part A Assume that light is incident normal to the surface of a film of thickness d. How much farther does the light reflected from the back surface travel than the light reflected from the front surface
Answer:
Λ = 2 t
Explanation:
This is a problem is interference by reflection, where it is requested not to take into account the changes of phase and change in the wavelength within the film
λₙ = λ₀ / n
When the wave enters the film, it must reach the end of the film, be reflected and reach the initial surface, therefore the total length is
d = 2 t
where t is the thickness of the film, because the film is perpendicular to the surface
therefore the difference in optical path between the reflected ray on the surface and the end film is
Λ = 2 t
3. What does the difference in force depend on?

Determine whether the interference is constructive or destructive at each location indicated.
A.constructive or destructive
B. constructive or destructive
C. constructive or destructive
D. constructive or destructive
Answer:
A. Constructive
B. Destructive
C. Destructive
D. Constructive
Explanation:
Constructive interference takes place at locations along the path of two superposed waves where the waves are in phase such that a high or low point of one of the waves corresponds with a high or low point of the other wave which gives a resulting wave amplitude which is the sum of the amplitudes of the individual waves
Destructive interference takes place at locations along the path of two superposed waves where one wave is out of phase with the other wave such that a high or low point of one of the waves coincides with a low or high point of the other wave respectively thereby cancelling the effect of the other wave and giving a resulting wave that has an amplitude which is the difference in the amplitudes of the individual waves
Therefore;
At point A, the peak of each wave partially coincides resulting in constructive interference
At point B, the peak of the blue wave and the trough of the red wave partially coincides resulting in destructive interference
At point C, the through of the blue wave and the peak of the back wave partially coincides resulting in destructive interference
At point D, the trough of each wave partially coincides resulting in constructive interference.

How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

As the signal turns green, automobile A accelerates at a constant rate of 2 m/s2. Two seconds later, automobile B starts and accelerates at a constant rate of 3.6 m/s2. Determine (a) when B will overtake A, (b) the speed of each automobile at that time, and c) the location where B overtakes A relative to the traffic signal.
Answer:
a) 45 s , b) vₐ = 90 m / s, v_b = 162 m / s, c) x_b = 3.328 10⁴ m
Explanation:
We can solve this exercise using the kinematic relations
Vehicle A
xₐ = v₀ₐ t + ½ aₐ t²
vehicle B
starts two seconds later
x_b = v_{ob} (t-2) + ½ a_b (t-2) ²
as cars start from rest their initial velocities are zero
at the point where they meet, the position must be the same for both vehicles
xa = 0 + ½ aₐ t²
xb = 0 + ½ a_b (t-2) ²
½ aₐ t² = ½ a_b (t-2) ²
[tex]\sqrt{ \frac{a_a}{a_b} }[/tex] t = (t-2)
t (1 - \sqrt{ \frac{a_a}{a_b} }) = 2
t (1 - ⅔, ) = 2
t = 2 / 0.4444
t = 45 s
b)
the speed of each car
vₐ = voa + aa t
vₐ = 0 + 2 45
vₐ = 90 m / s
v_b = 3.6 45
v_b = 162 m / s
c) xb = 0 + ½ ab (t-2) ²
x_b = ½ 3.6 (45-2) ²
x_b = 3.328 10⁴ m
The distance between the two nearest points on a wave where the particles are in phase is 2 m. What is the wavelength of the wave?
A. 1/2 m
B. 1 m
C. 2 m
D. 2 seconds
E. none of these
Answer:
Suppose that the wave equation is:
f(x) = A*cos(k*x)
The wave is in phase for two points x₁ and x₂ if:
f(x₁) = f(x₂)
And if these points are consecutive (for example, two consecutive peaks) then the wavelength of the wave is:
wavelength = x₂ - x₁
In this case, we know that the wave is in phase for two points that are 2 m apart.
Then we can use the points:
x₁ and x₂ such that:
x₂ = x₁ + 2m
We also know that these are the nearest points such that this happens, then we can assume that the points are consecutive.
Then the wavelength will be:
wavelength = x₂ - x₁ = (x₁ + 2m) - (x₁) = 2m
Then the wavelength is 2m.
The correct option is C.
The light is most intense where it strikes Earth _______ to its surface.
Answer: The sun's rays strike Earth's surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly, the area is heated more.
The light is most intense where it strikes Earth's surface most directly at the equator
The sun's rays strike Earth's surface most directly at the equator. The rays are focused on a narrow area as a result of this. The area is heated more because the sunlight touch it more directly.The incoming solar radiation is more direct (almost perpendicular or closer to a [tex]90[/tex] degree angle) when the sun's rays contact the Earth's surface near the equator. As a result, solar energy is focused over a smaller surface area, causing temperatures to rise.For more information:

Write your question here (Keep it simple and clear to get the best answer) a car accelerates uniformly from an initial velocity of 10m/s at 2m/s squre for 4s.What is the average velocity
Answer:
Average velocity = 18 m/s
Explanation:
Given the following data;
Initial velocity = 10m/s
Acceleration = 2m/s²
Time = 4 seconds
To find the average velocity, we would use the first equation of motion;
[tex] V = U + at[/tex]
Where;
V is the final velocity.
U is the initial velocity.
a is the acceleration.
t is the time measured in seconds.
Substituting into the equation, we have;

You and your younger sister (who weighs half as much you do) are at a skating rink. You and your sister's both move backward but your sister accelerates at a greater rate.
What is acceleration?The time rate of change of velocity with time.
As both are holding each other, they will be pushed backwards because the skating they wear makes them to move backwards. The equal and opposite force is applied on each other.
The force F =mass x acceleration.
The lesser mass greater will be the acceleration. Your sister with half weight of yours will accelerate more.
Thus, you and your sister's both move backward but your sister accelerates at a greater rate.

The Hubble telescope was placed in orbit in 1990 by the space shuttle and has since delivered the sharpest images we have of our planet, our galaxy, and the universe. The images delivered last week show the beautiful display of lights in the southern hemisphere. These lights are the result of the solar activity known as solar wind. Traces of solar wind reach well beyond Earth and have been detected as far as Saturn. Which statement in the news passage above is inaccurate
Answer:
The statement as aurora australis known as northern lights is incorrect. As the designation of aurora australis is for the southern lights i.e. which occur in the southern hemisphere.
Explanation:
Aurora or natural lights is a phenomenon that occurs at the poles of the Earth due to interaction between the Earth's magnetic field and cosmic rays. This interaction results in the beautiful display of colors on both poles. These are named, aurora borealis or aurora australis depending on their geographical location. If they occur on the northern pole they are termed as aurora borealis while those occurring on the southern pole are named aurora australis.
