Why do temperatures differ between air, land, and water?
Answer:the ocean water isn't moving into or through the atmosphere as a result of the sun's heating of the water, convection isn't the process influencing air and water temperature difference. The heat of the ocean is being given off radiated into the air, making the air substantially warmer
Explanation:
What happens during heat transfer within Earth?
Group of answer choices
Warmer, less dense material rises.
Explanation:
This happens when heat transfers.

Which of these changes would likely occur if the rate of Earth's rotation on its axis decreased? The length of day would be shorter F The length of day would be longer G The length of the seasons would be shorter. H The length of the season would be longer.J
Answer:
F. The length of day would be longer
Explanation:
Earths rotates on its axis from the eastward to the westward direction, earth takes about 24 hours to complete its rotation. If the rate of earth's rotation on its axis slows down then the days will be longer than usual. Thought the length of year would remain the same. Earth rotation is also impacted by the sun and moon's gravitational pull. The disappearance of the centrifugal force form the surface would cause climate changes and seasonal extremes.CAN SOMEONE HELP ME WITH THIS QUESTION!!

An object free falls for 3.5 seconds . How far does it fall?
Which element accumulates in the environment due to the use of
fertilizers?
A. oxygen
B. hydrogen
C. nitrogen
D. carbon
To Find :
Which element accumulates in the environment due to the use of fertilizers.
Solution :
Most of the fertilizers used in daily practice are nitrogen fertilizers .
When soil became waterlogged, soil organisms take the oxygen they need from nitrates, leaving the nitrogen in a gaseous form which escapes into the air.
Also, nitrogen is very stable and did not participate in most of the reactions.
So, nitrogen is accumulates in the environment .
Therefore, option C. is correct.
The nucleus of a cell is like the ____ of a large animal.
How far does the gravitational field of Earth extend?

Question 2 of 25
What is the voltage drop across the 20 resistor?
10.00
120.0 V
20.0 2.
www
30.02
The voltage drop across the 20 Ohm resistor is 40V.
To determine the answer, we need to know about the current flowing through the resistor.
What is the total resistance of the circuit?As the three resistors are connected in series, so the resultant resistance is
10 Ohmv+ 20 Ohm + 30 Ohm = 60 Ohm
What is the current flowing through the resistors?As these resistors are connected in series, so the amount of current flowing through each resistor is equal.According to Ohm's law, current = voltage/resistanceCurrent= 120/60 = 2 A
What is the voltage across the 20 Ohm resistor?According to Ohm's law, voltage across the 20 Ohm resistor
= current×resistance
= 2×20
= 40volt
Thus, we can conclude that the voltage across the 20 Ohm resistor is 40V.

Which best illustrates projectile motion
A pictorial diagram of a person hopping sideways at 5 different positions. The start and end positions are on the ground. The correct option is D.
What is projectile motion?Projectile motion is the motion of an artifact thrown or projected into the air that is only affected by gravity's acceleration. The object is known as a projectile, and its path is known as its trajectory.
Any object that is cast, fired, flung, heaved, hurled, pitched, tossed, or thrown is considered a projectile.
Throwing a ball straight up, kicking a ball at an angle to the horizontal, or simply dropping things and letting them fall are all examples of projectile motion.
The pictorial diagram of a person hopping sideways in five different positions best illustrates projectile motion. The starting and ending points are on the ground.
Thus, the correct option is D.

You and your team are trying to determine the height of each of victim. Which bone will you analyze to create a profile of the victims?
Answer:
Femur
Explanation:
The bone to forensically analyze in order to create a height profile of the victims would the femur.
The approximate height of a human can best be estimated by measuring the length of the bone that runs from the hip to the knee, otherwise known as the femur.
For the males, the length of the femur in centimeters is multiplied by 2.32 followed by the addition of 65.53 in order to arrive at the approximate height of the individual. For the females, on the other hand, the length of the femur in centimeters is multiplied by 2.47 followed by the addition of 54.1.
A 12 Volt car battery pushes charge through the headlight circuit resistance of 10 ohms. How much current is passing through the circuit?
Answer:
We applicate formula:
I = V/R
Replacing acording data:
I = 12 V / 10 Ω
Resolving:I = 1,2 A
Result:
The current is of 1,2 Amperes.
Answer:
1.2 amps
Explanation:
I = V/R
V = 12
R = 10
12/10 = 1.2 amperes (amps)

E20 GOT A HUNDRED PERCENTA compressed spring stores 720 J of energy. A 1 kg block rests on the end of the spring. The spring is released and comes back to its uncompressed length pushing the block away. What is kinetic energy of the block as it leaves the spring? What is the speed of the block at this instant?
Answer:
the kinetic energy of block will be equal to energy stored in spring ie 720 J
the speed of block will be 37.9 m/s
Explanation:
E = m v^2 / 2
v = sqrt (2 * E / m)
v = sqrt (2 * 720 J / 1 kg) = 37.9 m/s
