Answer:
D
Explanation:
Physics and Chemistry are the most basic disciples in science, so the answer is not A or B.
Mathematics is the language of science; it could be the answer.
Most likely, you are looking for logic which describes the validity of an argument that has already been developed. I would pick D, but your marker may not agree.
Why is physics used to study the heat absorbed by the ocean?
A. The ocean is important.
B. Heat is a form of energy.
C. The Sun gives off heat.
D. Physicists mostly study the ocean.
Answer:
B
Explanation:
It absorbs gases, but also heat energy from the atmosphere, distributes them in its depths and thus slows down changes in the entire Earth system. The amount of energy absorbed by the ocean is therefore also an indication of the total heat absorbed by the planet.
Answer:B

if earth would stop receiving heat and light about 8 min what happen
If the Sun disappeared suddenly, we wouldn't know about it for about 8 minutes ... that's how long it takes for heat and light from the Sun to get here to Earth.
8 minutes after the Sun disappeared, the sky would turn totally black. All plants would immediately stop growing ... including all the plants that people or animals eat to live.
Then, after a few more minutes, we would start to notice that it was beginning to slowly get cooler, and that would continue until Earth was too cold for anything to live on it.

Answer: x = 128°
180° - 52° = 128°
Answer:
128 degrees
Explanation:
A circle has a degree of 360, all around. You can imagine a circle, with the center being where the line intercepts the right angle.
360 = 52 + 38 + 142 + x
360 = 232 + x

What patterns related to the Moon do we still have left on our DQB, that we haven’t yet explained?
Answer:
What patterns can we observe in the sky?
Stars create observable patterns in the form of “dots”, which can be created to make pictures. These are called constellations. The constellations can move in position or location across the sky, but each “piece” in the constellation does not move because stars do not move or change position in relation to other stars.
What are the 12 phases of the moon?
The moon phases in order are new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, last quarter, waning crescent.
What pattern does the Moon travel around the Earth?
circular The moon orbits the earth in a nearly circular pattern every 27.3 days. The moon's orbit is tilted approximately 5 degrees off of the path of the plane of the ecliptic (or the path that the sun appears to trace across the sky), and orbits at a distance of almost 240,000 miles from the earth.
What patterns do you notice about the Moon and sun across the sky?
The sun follows the same pattern as the moon; it appears to rise in the east and set in the west. The Sun is Always Shining The sun is always shining, even at night when we cannot see it. The sun follows the same pattern as the moon; it appears to rise in the east and set in the west.
What causes the pattern of the Moon?
One important thing to notice is that exactly one half of the moon is always illuminated by the sun. ... So the basic explanation is that the lunar phases are created by changing angles (relative positions) of the earth, the moon and the sun, as the moon orbits the earth.
Explanation:
here are 8 standard phases of the moon, which is demonstrated in this particular diagram very clearly. There’s the new moon, waxing crescent, first quarter, waxing gibbous, full moon, waning gibbous, third quarter, waning crescent, and then back around to the new moon.
The most obvious patterns of the moon are the phases of the moon, which move in a month-long cycle. Because the moon reflects its light from the sun, only the part of the moon that faces the sun is visible. As the moon revolves around the Earth, its shadow covers part of its surface.
The Moon. In the natal chart, the position of the Moon by sign shows how we emote and respond to our environment, as well as our instinctual habits, especially in our homes and in private. By house, the Moon’s position shows which areas of life we feel the most “at home” or comfortable.
Patterns in the natural and human designed world can be observed, used to describe phenomena, and used as evidence. In the previous lesson, we determined two patterns for the moon: 1) The moon changes shapes. 2) The moon appears to rise, move across the sky, and set. In today's lesson, we focus in on the first pattern-- the moon's phases.

A 25 kg sled is pulled across a horizontal surface by a 200 N force at a constant velocity. What is the coefficient of friction between the sled and the surface?
Answer:
0.82
Explanation:
constant velocity.means acceleration a = 0, so net force = 0
F - μmg = ma = 0
so μ = F/(mg) = 200/(25*9.8) = 0.82
The main focus of the nervous system is to:
Answer:
The main focus of the nervous system is to have nerve fibers pass information throughout the body. The nervous system is crucial for keeping our bodies functioning. It is divided into two main parts, the peripheral nervous system, which are the nerves running throughout the body, and the central nervous system, which is the brain and spinal cord. The nervous system communicates signals between body parts and the brain. The nervous system keeps all body parts functioning through these signals.

Jhen swam 3 complete laps in a 70 meter pool. (1 lap is one length of the pool)
The total distance covered by Jhen is 210 m and the total displacement is zero (0).
Distance covered by JhenThe total distance covered by Jhen is calculated as follows;
D = 70 m x 3 (since 1 lap is equal to one length of the pool = 70 m)
D = 210 m
Displacement of JhenThe displacement of Jhen is the change in the final position and the initial position of Jhen.
After 3 laps, the final position = the initial position
Displacement = 0
Thus, the total distance covered by Jhen is 210 m and the total displacement is zero (0).

Which of the following is the most appropriate description of an electric current?
A rock is thrown vertically up and reaches a maximum height of 20m. What was its initial velocity?
Answer:
Solve it simply,
Vi = 20 m /sec
Vf = 0 ( at max. height)
g = - 9.8 m/ sq. sec. ( -ve sign shows that the motion of the body is in opposite direction to that of gravity)
Height it gains=h = ?
time taken by the body=t=?
Using 3rd equation of kinematics,
2gh=Vf ˄2 – Vi˄2
implies that
h = Vf ˄2 – Vi˄2 / 2a
h = 0˄2 - (20)˄2 / 2(-9.8) = - 400/ -19.6
h = 20.4 m
So the maximum height the body can gain is approximately equal to 20.4 m.
Now , using 1st equation of kinematics:
Vf = Vi + at implies that,
t = Vf - Vi/g = 0 - 20/ - 9.8 = 2.04 sec.
So, it will take 2.04 sec. to get the max. height.
Note: in simple approximation if we take g =- 10 m/ sq.sec then the max. height the body can attain will be 20 m and the time required for it, is 2 sec.

( 25 POINTS )There is a light pole on one bank of a small pond. You are standing up while fishing on the other bank. After reflection from the surface of the water, part of the light from the bulb at the top of the pole reaches your eyes. Use a ray diagram to help find a point on the surface of the water from where the reflected ray reaches your eyes.
Determine an expression for the distance from this point on the water to the bottom of the light pole if the height of the pole is H , your height is h , and the distance between you and the light pole is L .
You must answer in terms of these varibles.
Following the Law of reflection we can assume that the expression for the distance from the point of reflection on the water to the bottom of the light pole is d = (H (L-d)) / h.
What does the Law of Reflection state?
The Law states that the reflection angle -θ₂- of an incident ray on a reflecting surface will be equal to the incidence angle -θ₁- of that ray.
Both angles, the reflection and the incidence one, are measured conserning the normal to the surface.
The law of reflection derives from Fermat's principle and states that the triangle formed between the incident ray and the surface, and the triangle produced by the reflected light and the surface are the same.
In the exposed example, if
H is the height of the pole,h is the height of the person,L the distance from the person to the pole,d is the distance from the pole to the point of reflection,L - d is the distance from the person to the point of reflection.If,
θ₁ = θ₂
h/L-d = H/d
Then, the distance from the point of reflection on the water to the bottom of the light pole, d is
d = (H (L-d)) / h
