Explain how conduction, convection, and radiation drive the water cycle in Earth’s system.
Answer:
During the day, sunlight heats the ground, which in turn heats the air directly above it via conduction. At night, the ground cools and the heat flows from the warmer air directly above to the cooler ground via conduction.
Explanation:
Luck For You!
The process, in which conduction, convection, and radiation drive the water cycle in Earth’s system, is discussed in the answer.
What is water cycle?The energy from the sun is what largely drives the water cycle. By evaporating water from the oceans, lakes, rivers, and even the soil, this solar energy powers the cycle. Through the process of transpiration, more water is transferred from plants to the atmosphere. Water droplets gradually acquire enough mass to fall back to Earth as precipitation as liquid water evaporates or transpires, forming clouds and water vapour.
The precipitation eventually transforms into runoff or groundwater and makes its way back into the surface reservoirs across a variety of periods. The hydrosphere currently contains the same amount of water as it has always contained in the Earth system since the water cycle is essentially a closed system.
Solar heat energy comes on earth's surface via radiation to the ponds, lakes, oceans, seas, rivers and other water resources and then the waterbodies get heated via conduction and evaporation happens. During evaporation time temperature water vapor goes to high altitude via convection of heat and cloud forms.

Moral Dilemma A man is sitting at home worrying about the fact that his daughter needs a major surgery in order to continue living, but he does not have the money to pay for it. He has asked family and friends to help with the cost of the surgery, but he was only able to raise about a quarter of what the surgery costs. He then remembers that he has power of attorney (i.E., control over someone else's finances/legal issues) for his out-of-touch-with-reality, but healthy, 85-year-old father. The man could, without anyone knowing, use his father's money to pay for the surgery. However, this would leave his father with only one year of living expenses. The man decides to take his father's money for his daughter's surgery. Should the man have done that? Why?
Answer:
Mostly with aid of Kohlberg 's moral growth theory, I clarify this answer, which would also be separated into three stages under which this particular problem is illustrated below.
Explanation:
Pre conventional Stage:The daughter's father would think about either the penalty during that point if he commits any wrongdoing or breaches laws to save her daughter. But another way to make that happen for surgery is that a person cares about either the legislation and rules as well as the significance of respecting them throughout the pre-conventional process. He will also attempt to establish its insight into solving these problems.
Conventional Stage:As per the traditional process of the spiritual psychosocial development of Kohlberg, her father would think of civilization because there are conventions that unless he borrows money of his dad again for the procedure of their daughter, culture would label him greedy or prejudice against him to pay the profits of his father despite his consideration.
Post conventional Stage:As per this argument, he might determine for her child as well as father in his philosophy including perspectives, which means that his father is not in the situation of requesting credit, but because he's in a position to give a recommendation, therefore he certainly gives authorization rescue her grandchildren even though she is small and has several activities to do in hers life. And subsequently, with emerging profits, he will take care of his father as well as daughter, and nowadays focus says their daughter wants treatment to recover.

4. Calculate the momentum for each scenario:
a. .02 kg mass moving at 300 m/s
b. 2 kg mass moving at 40 m/s
c. 200 kg mass moving at 4 m/s
a) Answer:
Momentum = 6 kgm/s
Explanation:
Momentum = mass × velocity
Given that,
mass = 0.02 kg velocity = 300 m/s
Therefore, momentum = (0.02 × 300)kgm/s
Momentum = 6 kgm/s
b) Answer:
Momentum =80 kgm/s
Explanation:
Momentum = mass × velocity
Given that,
mass = 2 kg velocity = 40 m/s
Therefore, momentum = (40 × 2)kgm/s
Momentum = 80 kgm/s
c) Answer:
Momentum = 800 kgm/s
Explanation:
Momentum = mass × velocity
Given that,
mass = 200 kg velocity = 4 m/s
Therefore, momentum = (200 × 4)kgm/s
Momentum =800 kgm/s

Answer:
9) a = 25 [m/s^2], t = 4 [s]
10) a = 0.0875 [m/s^2], t = 34.3 [s]
11) t = 32 [s]
Explanation:
To solve this problem we must use kinematics equations. In this way we have:
9)
a)
[tex]v_{f}^{2} = v_{i}^{2}-(2*a*x)\\[/tex]
where:
Vf = final velocity = 0
Vi = initial velocity = 100 [m/s]
a = acceleration [m/s^2]
x = distance = 200 [m]
Note: the final speed is zero, as the car stops completely when it stops. The negative sign of the equation means that the car loses speed or slows down as it stops.
0 = (100)^2 - (2*a*200)
a = 25 [m/s^2]
b)
Now using the following equation:
[tex]v_{f} =v_{i} - (a*t)[/tex]
0 = 100 - (25*t)
t = 4 [s]
10)
a)
To solve this problem we must use kinematics equations. In this way we have:
[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]
Note: The positive sign of the equation means that the car increases his speed.
5^2 = 2^2 + 2*a*(125 - 5)
25 - 4 = 2*a* (120)
a = 0.0875 [m/s^2]
b)
Now using the following equation:
[tex]v_{f}= v_{i}+a*t\\[/tex]
5 = 2 + 0.0875*t
3 = 0.0875*t
t = 34.3 [s]
11)
To solve this problem we must use kinematics equations. In this way we have:
[tex]v_{f} ^{2} = v_{i} ^{2} + 2*a*(x-x_{o})[/tex]
10^2 = 2^2 + 2*a*(200 - 10)
100 - 4 = 2*a* (190)
a = 0.25 [m/s^2]
Now using the following equation:
[tex]v_{f}= v_{i}+a*t\\[/tex]
10 = 2 + 0.25*t
8 = 0.25*t
t = 32 [s]
An object with a charge of 1.2 C is located 4.5 m away from a second object that has a charge of 0.36 C. Find the electrical force that the objects exert on each other. Use 8.988×10 N⋅m2/C2 for the value of Coulomb's constant. Give your answer to two decimal places.
Answer:
[tex]1.917*10^8\ N[/tex]
Explanation:
Coulomb's law states that the electric force between two charges is directly proportional to the product of the two charges and inversely proportional to the square of the distance between them. It is given by the formula:
[tex]F=k\frac{q_1q_2}{r^2}\\ \\q_1=first\ charge = 1.2C,q_2=second\ charge=0.36C,k=coulomb\ constant=8.988*10^9 N.m^2/C^2, r=distance=4.5m,F=force\\\\F=8.988*10^9*\frac{1.2*0.36}{4.5^2} =1.917*10^8\ N[/tex]

Two fish swimming in a river have the following equations of motion:
X 1 = - 6.4 m + (- 1.2 m/s) t
X 2 = 1.3 m + (- 2.7 m/s) t
Which fish is moving faster?
Answer:
The second fish, X2, is moving faster than the first fish, X1
Explanation:
The given parameters for the equation of motion of the fishes are;
X1 = -6.4 m + (-1.2 m/s)×t
X2 = 1.3 m + (-2.7 m/s)×t
The given equation are straight line equations in the slope and intercept form, where the slope is the speed and in m/s and the intercept is the starting point of swimming of the fishes
For the first fish, the intercept = -6.4 m, the slope = the speed = -1.2 m/s
For the second fish, the intercept = 1.3 m, the slope = the speed = -2.7 m/s
Whereby the fishes are swimming in the opposite direction of the measurement of length, we have;
The magnitude of the speed of the second fish [tex]\left | -2.7 \ m/s \right | = 2.7 \ m/s[/tex], is larger than the magnitude of the speed of the first fish [tex]\left | -1.2 \ m/s \right | = 1.2 \ m/s[/tex]
Therefore, the second fish, X2, is moving faster than the first fish, X1.

Newton's First Law of Motion :
An object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .
Here this statement is best represented by the statement : Unbalanced forces cause an object to move. [ option c ]
More to know :-
Newton's 3 laws of motion :-
Newton's First Law of Motion :-
It states that an object stays in rest or in uniform motion unless and until compelled by an external unbalanced force . This is also known as " Law of Inertia " .
Ex - (i) We tend to fall backwards while standing in the bus , when it starts suddenly.
(ii) We tend to fall forward while standing in the bus , when it stops suddenly.
Newton's Second Law of Motion :-
It states that the rate of change of momentum is directly proportional to the applied force in the direction of the force . That is ∆p [tex]\propto[/tex] Force .
Ex - (i) When we push car & a truck with same force the car will have Greater acceleration due to less mass . (Imaginary case ).
(ii) We feel easy to push a empty cart than a full cart .
Newton's Third Law of Motion :-
It states that every action has equal and opposite reaction .
Ex - (i) We are able to walk on ground due to Newton's third law of motion .
(ii) When we push wall it also applies equal and opposite force .
"Unbalanced forces cause an object to move " is the sentence that describes Newton's first law.
Describe Newton's first law.A body remains in the state of rest or uniform motion in a straight line unless and until an external force acts on it.
The object is to be rest if the velocity and acceleration are zero. When an object is in motion, velocity is not equal to zero (v ≠ 0) but acceleration (a = 0) is equal to zero. Therefore, the object will continue in motion with constant velocity in the same direction.
Example:
If we jump from a bus while moving, our body will be like still moving in the same direction of the vehicle. When your feet hit the ground, the grounds act on your feet and stop moving. You will fall because the upper part of your body didn't stop and you will fall in the direction you were moving.
If the object have the greater mass, then the object will have more inertia. Forces can change the object's motion.
Hence, Option D is the correct answer.

Please help will give brainliest to whoever does a 4 setence answer
In a distance time graph, when the x and y values are positive (in first quadrant), the runner is moving forward.
While, if the distance value ( in the y axis) is negative, the runner is moving backwards ( towards the start) .
Hope it helps :)
A distance-time graph shows how far an object has travelled in a certain time. This is a simple line graph that plots observations by distance versus time.
The distance is transferred to the Y axis.
Time is plotted on the X-axis.
The distance-time graph when we study the motion of bodies. If you set the distance and time of the movement of the object and transfer the same data to a rectangular graph, you will get a distance-time graph corresponding to the movement of the object.
