Answers
Answer:Earth is a truly unique in its abundance of water. Water is necessary to sustaining life on Earth, and helps tie together the Earth's lands, oceans, and atmosphere into an integrated system. Precipitation, evaporation, freezing and melting and condensation are all part of the hydrological cycle - a never-ending global process of water circulation from clouds to land, to the ocean, and back to the clouds. This cycling of water is intimately linked with energy exchanges among the atmosphere, ocean, and land that determine the Earth's climate and cause much of natural climate variability. The impacts of climate change and variability on the quality of human life occur primarily through changes in the water cycle. As stated in the National Research Council's report on Research Pathways for the Next Decade (NRC, 1999): "Water is at the heart of both the causes and effects of climate change."

What is the density at 20oC of 12.0 milliliters of a liquid that has a mass of 4.05 grams?0.338 g/mL
2.96 g/mL
16.1 g/mL
48.6 g/mL
Answers
Explain:
D = m/V = 4.05/12 = 0.3375 = 0.338 g/mL
The density at 20°C of 12.0 milliliters of a liquid that has a mass of 4.05 grams is 0.3375g/mL.
HOW TO CALCULATE DENSITY:
The density of a liquid can be calculated by dividing the mass of the liquid by its volume. That is;Density (g/mL) = mass (g) ÷ volume (mL)According to this question, a liquid at 20°C has a volume of 12.0 milliliters and a mass of 4.05 grams. The density is calculated as follows:Density (g/mL) = 4.05g ÷ 12mLDensity of liquid (g/mL) = 0.3375g/mLTherefore, the density at 20°C of 12.0 milliliters of a liquid that has a mass of 4.05 grams is 0.3375g/mL.Learn more about how to calculate density at: https://brainly.com/question/2040396?referrer=searchResults

Answers
Mateo and Jackie were on a playground rolling some different-sized balls to get them to crash. They used a tennis ball (the same mass) in both crashes. They tried two soccer balls—a pink one (more mass) for Crash 1 and a blue one (less mass) for Crash 2.
Mateo and Jackie want to know what happened to the tennis ball. Use information from the diagram to answer.
In which crash did the tennis ball experience a stronger force? How do you know?
a
Crash 1; the force on the soccer ball was stronger in this crash, so the force on the tennis ball was also stronger.
b
There was no force on the tennis ball. In each crash, only the soccer ball experienced a force.
c
It was the same in both crashes. The soccer ball changed speed by the same amount in each crash, so the force on the tennis ball was the same both times.
d
The diagram doesn’t tell you anything about the force on the tennis ball. It only gives information about the force on the soccer balls.
Answers
Answer:
In crash one, because the pink soccer ball had more mass, so it would have a stronger force.
Force is mass multiplied by acceleration. Therefore , option (A) Crash 1 ; the force on the soccer ball was stronger in this crash, so the force on the tennis ball was also stronger.
What is force?A push or pull acting on an object as a result of that object's interaction with another object is what we refer to as a force. Each object experiences a force whenever there is an interaction between two other objects because both objects are subject to the force.
According to the first law of motion, an object's motion will not change unless there is a force acting on it. According to the second law of motion, the amount of force exerted on an object is proportional to the product of the object's mass and its acceleration. According to the third law, when two objects interact with each other, the forces that they apply to each other are of equal magnitude but opposite direction.
Therefore, option (A) is correct.

Lan tries to make a 10 W lightbulb light up by connecting it to a battery with
an insulated copper wire. When the lightbulb does not light up, she assumes
that the battery is dead. What can she do to make an electric current flow
through the lightbulb?
A. Replace the battery with a coil of the wire, and then pass a magnet
back and forth through the coil.
B. Replace the battery with a magnet, and then pass a piece of wire
back and forth over the magnet.
O C. Wrap a magnet with several coils of the wire, and then hold the
lightbulb close to the wire.
D. Wrap the lightbulb with several coils of the wire, and then hold a
magnet close to the wire.
Answers
Answer:
A
Explanation:
When a magnet passes through something that's copper, there is a reaction that generates an electric pulse. Passing a magnet back and forth through the wire is much more likely to generate the electrical charge needed then the other options given.
Lan can replace the battery with a coil of the wire, and then pass a magnet back and forth through the coil to make an electric current flow through the lightbulb. Hence option (A) is correct.
What is electromagnetic induction ?The generation of an electromotive force (emf) across an electrical conductor in a fluctuating magnetic field is known as electromagnetic or magnetic induction.
Induction was first observed in 1831 by Michael Faraday, and James Clerk Maxwell mathematically named it Faraday's law of induction. The induced field's direction is described by Lenz's law. One of the four Maxwell equations in his theory of electromagnetic, the Maxwell-Faraday equation is a generalization of Faraday's law.
When Lan replace the battery with a coil of the wire, and then pass a magnet back and forth through the coil, it generates electromagnetic induction and electric current flows through the lightbulb.

Read the excerpt from "Healthy Eating."
But no one can ignore the damage being wrought by all this bad eating. More than one out of three adults in the United States -- 37.5 percent -- are obese, according to the Centers for Disease Control and Prevention. Some of the leading causes of death -- heart disease, stroke and type 2 diabetes -- are directly linked to obesity. And childhood obesity has tripled in the last 30 years. With more than a third of kids between 6 and 19 considered obese, the CDC reports, they are at substantially more risk for developing cardiovascular disease, diabetes, bone and joint conditions, and cancer.
