A teacher places four books of different masses in a bookcase. The diagram shows the placement of the four books

The teacher states that the books are arranged in the bookcase for the lowest overall potential energy when only one book is on each shelf.

a. Use inequality symbols (<, >) to identify the relationship among the masses of all four books.

b. Describe how the arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf.

Answers

Answer 1

a.  P.E(Y)<  P.E(W)<  P.E(Z)<  P.E(X)

mass m(Y)< m(W)<m(Z)<m(X)

b. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.

What is gravitational potential energy?

If an object is lifted, work is done against gravitational force. The object gains energy.

The equation for calculating gravitational potential energy is

GPE =mgh

where, GPE is the gravitational potential energy, m is the mass, h is the change in height and g is the acceleration due to gravity.

a) According to the heights of books, P.E(Y)<  P.E(W)<  P.E(Z)<  P.E(X)

when arranged for lowest potential energy, book with the lowest mass will be placed in the lower position. Thus, relationship among masses, m(Y)< m(W)<m(Z)<m(X)

b)  The arrangement of the books can be changed for the greatest overall potential energy when only one book is on each shelf. The books arranged with book X in the bottom, book Z in 2nd position, book W in 3rd and book Y on the top.

Answer:

  A. The probable direction of storm movement for the next 12 hours.

Explanation:

In the northern hemisphere, air circulation is counterclockwise around a low pressure system. The arrow drawn on the diagram is below (south of) the center of low pressure, so the winds will be to the east in that area. The arrow is pointed in the direction of probable frontal system movement.

__

Other answer choices:

The map is of a portion of the eastern part of the North American continent. There is no ocean in the area of the frontal system or the arrow, so ocean currents are irrelevant to what the arrow is showing.

Convection currents in the atmosphere are vertical air currents. The horizontal arrow cannot show anything about convection currents.

Due to jet stream and trade wind direction over North America, the storm system shown would have originated farther to the north and west. The arrow points to the east northeast, so is not pointing in the direction of the origin of the storm system.

Mass = The amount of matter in an object (nothing related here)Volume = How much space is the object taking (super related here)

It's VOLUME here and not MASS here because:

It it would be Mass, then the object size could be anything, but the liquid wouldn't move as much higher. But because it is Volume, it is taking space, which makes the liquid moveIf the Mass would be the answer, then it would be totally not related, because mass isn't related over here, it matters about size.

Answers

Answer:

The Earth is a very bright object when viewed with a light telescope. The light from the sun reflects off of the Earth's surface and this makes it very difficult to see anything else.

Explanation:

The brightness of the Earth makes it difficult for an alien to view it with a light telescope. The light from the sun reflects off of the Earth's surface and this makes it very difficult to see anything else. The light from the sun can also cause the Earth's atmosphere to glow, making it even harder to see anything else.

from space, with the reflections of the sun and other vectors of light, the earth is pretty bright for the normal human eye. if the alien has similar optics, it would be quite difficult to see the earth in good detail

1. Why is only a small portion of the solar energy that strikes Earth's atmosphere stored by primary producers?

Answers

Explanation:

only a fraction of radiation strikes plants or algae and only a portion of that fraction is of wavelengths suitable for photosynthesis and much energy is lost as a result of reflection or heating of plant tissue

Only a small portion of the solar energy that strikes Earth's atmosphere is stored by primary producers primarily due to the limitations and inefficiencies in the process of photosynthesis.

Photosynthesis is the biological process by which primary producers (such as plants, algae, and some bacteria) convert solar energy into chemical energy in the form of glucose (a type of sugar). However, photosynthesis is not a perfectly efficient process, and several factors contribute to the small fraction of solar energy being stored:

Reflection and Absorption: Not all incoming solar energy is absorbed by the plants. Some of it is reflected back into space or absorbed by other substances in the atmosphere, water bodies, or the Earth's surface before reaching the photosynthetic organisms.

Wavelengths: Solar energy reaches Earth in the form of electromagnetic radiation, which includes different wavelengths. Chlorophyll, the primary pigment responsible for capturing light during photosynthesis, is most efficient at capturing certain wavelengths, particularly in the blue and red regions of the electromagnetic spectrum. The rest of the spectrum is less effectively utilized by the photosynthetic organisms.

Light Availability: Photosynthesis requires sunlight, so the amount of energy captured is also influenced by factors like the length of day and cloud cover. Weather conditions can limit the availability of sunlight, impacting the overall energy capture.

Respiration: Plants and other primary producers also use some of the energy they capture for their metabolic processes, including respiration, where they consume glucose to obtain energy for growth, maintenance, and reproduction. This reduces the net amount of energy stored as biomass.

Losses in Growth and Reproduction: Not all stored energy is converted into plant biomass. Some energy is used in growth and reproduction, while some is lost as heat during metabolic processes.

Hence, these factors contribute to the limited efficiency of photosynthesis and explain why only a small portion of the solar energy that strikes Earth's atmosphere is stored by primary producers as chemical energy in their tissues.
