Which sentence most accurately describes electrically charged objects?
They are attracted to one other without coming into contact.
They are negatively charged objects that are attracted to each other.
They attract or repel other charged objects without touching them.
They attract other objects after they have been in contact with them.
Answers
Answer:
They attract or repel other charged objects without touching them.
Explanation:
Charged objects have electrostatic forces of attraction. They are an example of non-contact forces that is, they exert a push or pull on other objects without touching them.
You observe that the hair on your head stands up when a charged balloon is brought near without touching your head. Based on this observation, you write down the following question and steps to an experiment.
Can two charged objects be attracted to each other without touching?
Step #1: Bring the charged balloon 10 cm from your head.
Step #2: Charge the balloon by rubbing it against a cloth.
Step #3: Record your observation.
Step #4: Bring the charged balloon 5 cm from your head.
Step #5: Record your observation.
What revision could you make to improve the experiment?
Remove the fifth step, you do not need to make multiple observations in an experiment.
Reverse the first two steps so that you charge the balloon before you bring it close to your head.
Reverse the second and third steps so you record your observation before you charge the balloon.
Swap steps two and four, you do not need to charge the balloon until the end of the experiment.
Answers
Answer:
yes it can be attracted without touching The electric force is a non-contact force. Any charged object can exert this force upon other objects - both charged and uncharged objects.

The surface tension of isopropyl alcohol in air has a value of 22.39 units and
the surface tension of water in air is 72.86 units. Which two statements are
true?
A. Isopropyl alcohol will have a higher boiling point than water
because the forces between the molecules are greater.
B. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller.
c. Isopropyl alcohol will have a more curved meniscus than water
because the forces between the molecules are greater.
D. Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller.
Answers
Answer:
B. Isopropyl alcohol will have a lower boiling point than water
because the forces between the molecules are smaller.
D. Isopropyl alcohol will have a flatter meniscus than water because
the forces between the molecules are smaller.
Explanation:
Isopropyl alcohol will have a lower boiling point than water because the forces between the molecules are smaller. Isopropyl alcohol will have a flatter meniscus than water because the forces between the molecules are smaller. Hence, options B and D are correct.
What is surface tension?Surface tension is the force that acts parallel along the surface of a liquid which in turn makes the surface of the liquid behaves like an elastic material.
Surface tension, as the name implies, acts on the surface of a liquid giving it some elastic properties; it is a product of the inherent properties of the molecules of the liquid.
For example, water possesses surface tension which is why when a pin or a needle is gently placed on the surface of the water it floats. Surface tension also accounts for the fact that some insects can walk on water.
Hence, options B and D are correct.

Analyze the forces acting on the crate shown in the diagram. Explain why the crate will not move in the direction of the applied force. (Fapp.)
Answers
The crate will not move in the direction of the applied force because in the image there are two forces.
What is force ?A force is an influence that has the power to alter an object's motion. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
Force is used to describe a body's tendency to modify or change its state as a result of an external cause. When force is applied, the body can also alter its size, shape, and direction.
Contact forces and act at a distance forces are the two different types of forces. Your daily use of force is evident. Basically, push and pull are forces. You exert force on an object when you push against it or pull against it.
Thus, The crate will not move in the direction of the applied force because in the image there are two forces.

What is the most likely adaptation for a rabbit which once lived in the snow but now lives in shrubs and rocks due to increased global temperatures?
They will see an increase in fur production
They will become better swimmers
They will grow longer ears
Their coats will become darker due to natural selection
Answers
The most likely adaptation of a rabbit that moves from snow to shrubs and rocks would be a darker coat color due to natural selection.
What is adaptation?It is the physiological and or morphological changes that occur in organisms that enable them to survive in their environments.
A rabbit that moves from living in the snow to living in shrubs and rocks does not need to produce more fur to survive as the temperature will be higher than in the snow.
Also, such a rabbit does not need to become a better swimmer since it is not living in the water. A longer ear also has no bearing in adapting it to its new environment.
A darker coat color, however, will conceal it from predators and give him a selection advantage.

How does the ocean affect the rate of accumulation of [tex]CO_{2}[/tex] in the atmosphere?
increases it
decreases it
maintains it at a constant rate
Answers
Answer:
The ocean is a large CO2 sink because of its large surface area. The CO2 emissions are caused by human and manufacturing activities which some of them are absorbed in the ocean because CO2 is partly soluble in water. Thus, the answer is CO2 is decreased in the process.
CO2 is part of the carbon cycle and as such, moves from the land to the atmosphereby human burning of fossil fuels and forest fires,. But CO2 also moves from the atmosphere into the oceans when when the solubility is right - this is called an ongoing "flux" or movement of CO2 in and out of the oceans. Hence the oceans act as a kind of buffer to ensure that not too much CO2 remains in the atmosphere and hence the greenhouse effect will not get too strong.When the oceans are colder, they can absorb more CO2 out of the atmosphere, and when they warm up, they tend to release it back into the atmosphere. However, global warming is also now transferring heat from the atmosphere to the oceans and so the oceans are less inclined to absorb excess CO2 from the atmosphere. Also, as the oceans absorb excess CO2 from the atmosphere, this tend to make the salinity of the oceans become more acidic.
