Amani wants to know if crushed ice or whole ice melts faster. She puts the whole ice in a bowl on the kitchen counter. She puts the crushed ice in a bowl in the oven. Lastly, she times both bowls of ice to see which melts fastest. Is this a valid experiment? Why or why not?
Yes,
Because she wants to know which melts faster so she puts a bowl of crushed ice in a oven, which in then can melt it. If she turns on the oven light she will be able to understand if it melts.
If she leaves it out on the counter the regular un-crushed ice, she can see if that is also melted faster but this is in fact a valid experiment.

Answer:
It is hard to spilt a nucleus.

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
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.

What is the difference between stressed and bleached coral?
PLEASE I BEG YOU
Answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching.
What causes the formation of mountain ranges along the ocean floor?
Sediment from rivers causes added sediments until mountains are formed.

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.)
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.

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.
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.

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.
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.
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.

Answer:
The answer is B! (Reverse the first two steps so that you charge the balloon before you bring it close to your head)
