Sarah lives beside the ocean in Eureka, California. Her penpal, Ruby, lives in Redding, California, which is located inland.
As a school project one year, Sarah and Ruby decide to collect local climate data and compare the average monthly high and low temperatures from their cities. The data they collect are shown below.
Based on the climate data that Sarah and Ruby collect, they can conclude that
A. locations by the ocean typically get much colder in the winter and much hotter in the summer than locations that are located inland.
B. locations by the ocean typically get much less precipitation during the winter than locations that are located inland.
C. locations by the ocean typically get much less precipitation during the summer than locations that are located inland.
D. locations by the ocean typically do not get as cold in the winter or as hot in the summer as locations that are located inland.

Humans are organisms that live on the surface of the Earth.
In recent years, many products that people use have released chemicals into the air. This has slightly changed the composition of the air that surrounds the planet.
Which statement describes this interaction?
A. The geosphere interacted with the hydrosphere.
B. The biosphere interacted with the atmosphere.
C. The hydrosphere interacted with the biosphere.
D. The atmosphere interacted with the geosphere.
Please answer fast! (^V^)
Answer:
the answer is c
Explanation:
The Biosphere interacted with the atmosphere. The biosphere represents the zone where all living organisms inhabit. Human beings are leaving organisms and they have released chemicals that change the composition of the atmosphere.
The hydrosphere represents the regions of the earth occupied by water and the geosphere is the solid layer that is the earth's crust.

Early one October you go to a pumpkin patch to select your Halloween pumpkin. You lift a 3.2-kg pumpkin to a height of 0.80 m to check it out. How much work do you do on the pumpkin when you lift it from the ground?
Answer:
2.56J
Explanation:
The work done in lifting up the pumpkin is 25.1 J.
We must know that the work done when the pumpkin is lifted up a distance of 0.8 m is obtained using the formula of work done under gravity. Hence, applying that formula;
Work done = mgh
m = mass
g = acceleration due to gravity
h = height
Work done = 3.2 Kg × 9.8 ms-2 × 0.80 m
Work done = 25.1 J

With electromagnetic induction, what are 3 things that can be done to increase the electric current?
-Use a stronger magnet.
-Increase the speed at which the magnet moves.
-Reduce the turns to the coiled wires.
-Add more turns to the coiled wires.
-Use a bigger magnet
Answer:
-Add more turns to the coiled wires.
-Increase the speed at which the magnet moves.
-Use a stronger magnet.
Explanation:
To increase the electric current in magnetic induction, add more turns to the coiled wires, use a stronger magnet, and Increase the speed at which the magnet moves, so options A, B, and D are correct.
What is electromagnetic induction?Utilizing the interaction between electricity and magnetism, electromagnetic induction creates a magnetic field around a single wire when an electric current flows through it. The magnetic field is substantially enhanced if the wire is twisted into a coil, creating a static magnetic field around itself in the shape of a bar magnet with a clear North and South pole.
As a result, a coil's ampere-turns are what decide how strong its magnetic field is. The coil's static magnetic field is stronger the more wire turns there are inside of it.
Therefore, to increase the electric current add more turns to the coiled wires, use a stronger magnet, and Increase the speed at which the magnet moves.

Answer:
2207
Explanation:
A male elephant is about 6000kg, while the roosters of the golden comet chicken average on about 2,72kg. So if we divide 6000 by 2,72 we get about 2206 roosters for a draw. By this logic it would take 2207 chicken to kill an elephant
