Identify and describe the features found on the ocean basin floor?

Answers

Answer 1
Answer:
 The significant figures include  the mountainous ocean ridges, deep-sea trenches, and jagged, linear fracture zones. Other significant features of the ocean floor include aseismic ridges, abyssal hills, and seamounts and guyots. The basins also contain a variable amount of sedimentary fill that is thinnest on the ocean ridges and usually thickest near the continental margins.

. A student thinks that the more protons an atom has, the more reactive it will be. Which will best disprove this student's idea?Compare the reactivities of lithium (Li) and krypton (Kr).
Note that rubidium has 48 neutrons.
Compare the number of protons in cesium (Ce) and xenon (Xe).
Count the number of neutrons in an atom of helium.

Answers

The best answer to the question that is being stated above would be the first choice. To disprove the claims of the student that you need more protons to have more reactivity, then you proceed to compare the reactivities of lithium (Li) and krypton (Kr). Krypton has more protons than Lithium, but it is less reactive because it is a noble gas.

Comparing the reactivities of lithium (Li) and krypton (Kr) will best disprove this student's idea.

What is a Proton?

This is defined as a subatomic particle which has a positive charge present in it.

To disprove the claims of the student that you need more protons to have more reactivity, option A was chosen because Krypton has more protons than Lithium, but it is less reactive because it is a noble gas.

The graph below shows the blackbody radiation curves for four stars.Based on the graph, which of these conclusions is correct?

The star with very long wavelength does not emit light in the red part of the spectrum.
The star with very short wavelength does not emit light in the blue part of the spectrum.
The star with a wavelength of approximately 500 nm does not emit light in the green part of the spectrum.
The star with a wavelength of approximately 500 nm does not emit light in the red part of the spectrum.

Answers

The right answer for the question that is being asked and shown above is that: "The star with a wavelength of approximately 500 nm does not emit light in the red part of the spectrum." Based on the graph, wavelengths at approximately 500mn has less chance or can not emit light at the red part.

Why does it take less time for small rocks to wear away than it does for large rocks to wear way?

Answers

If you take one large rock it only wears away on its surface.

If you now break that rock in half the surface is the old outside AND the new break in half - therefore more surface area to wear away. Break these two halves again and there is more surface area to wear away.

Keep going and break your large rock into many pieces and you get small rocks which wear away much quicker.
It is because that small rocks are lighter than large rocks. It is hard for larger rocks because they are very heavy.

Maria’s father started a fire in the fireplace. He crumpled some paper, lit a match, and soon the logs in the fireplace were burning. In this case, the stored chemical energy in the logs was changed intoA) electrical energy.
B) mechanical motion.
C) heat and light energy.
D) electrical and heat energy.

Answers

As per the question the crumpled paper was burnt .

When the paper was burnt,it produces light.One also feels the sensation of heat.

The electrical energy is due to the flow of electrons. Here no electronic motion takes place.Hence no electrical energy will be produced.

Mechanical energy is the sum total of kinetic and potential energy.The kinetic energy is the energy gained due to the motion of the body and potential energy is the energy gained due to the position or configuration of the body.

Hence from above,we can get that the correct answer to the question is-C] Heat and light energy.
It was changed into heat and light energy.

Brody and Ethel are arguing about waves. Brody says that waving his hand back and forth is a scientific wave. Ethel says that it is not. Which statement best describes who is correct? -Brody is correct because the wave involves an input of energy. -Ethel is correct because energy is not carried from one place to another. -Brody is correct because the pattern repeats. -Ethel is correct because the motion has no pattern. Also... Khalad is measuring the amplitude of a wave. What can be known about this wave? -It is a sound wave. -It is a transverse wave. -It is an electromagnetic wave. -It is a mechanical wave.

Answers

In the first question, the answer would be the statement 'Brody is correct because the wave involves an input of energy'. The hand wave involves an input of energy and this energy is repeated and is carried from one place to another. 

For the next question, the answer would be 'it is a transverse wave' because all are transverse waves. 

Answer:

Ethel is correct because energy is not carried from one place to another.

It is a transverse wave.

Explanation:

During the propagation of waves from one point or place to another, energy is being transferred. Thus, when one's hand is being waved, there is no transfer of energy from one point to another. Therefore, Ethel is right while Brody is wrong.

A transverse wave is known as a type of wave that the direction of propagation is perpendicular to the vibration of the medium. Therefore, the wave is a transverse wave.

because the snow suddenly gets too slushy, you decide to carry your 100-newton sled the rest of the way home. How much workdo you you do when you pick up your sled, lifting it 0.5meter upward? How much work do you do to carry the sled if your house is 800 meters away?

Answers

You do 50 Joule work when you pick up your sled, lifting it 0.5meter upward.

You do no work to carry the sled to your home.

What is work?

Work in physics is the energy that is transferred to or from an item when a force is applied along a displacement. For a constant force acting in the same direction as the motion, the work is simply equal to the product of the force's magnitude and the distance travelled.

When a force is applied, it is said to have a component that moves the point of application, or it is said to have positive work.

Hence, lifting it 0.5meter upward, you have to work = weight of the sled × distance × cos 0°

= 100 N × 0.5 meter × 1

= 50 Joule.

To carry the sled to your home,  you have to work = weight of the sled × distance × cos 90°

= 100 N × 800 m × 0

= 0.

"One step in the manufacture of silicon wafers used in the microelectronics industry is the melt crystallization of silicon into a crystalline silicon ingot. This processis carried out within a special furnace. When the newly solidified ingot is removed from the furnace, it is assumed to have a uniform initial temperature of 1600 K, which is below the crystallization temperature. At this temperature, the thermal conductivity of silicon is 22 W/(m•K), the density is 2300 kg/m3, and the heat capacity is 1000 J/(kg•K). The hot solid silicon ingot is allowed to cool in air maintained at a constant ambient temperature of 30°C. The diameter of the silicon rod is 15 cm. End effects are considered negligible. The convective heat transfer coefficient is 147 W/(m2•K). What temperature will exist 1.5 cm from the surface of the ingot after a cooling time of 583 sec (9.72 min)?" Consider the rod as acylinder placed vertically.
