The roller coaster is your favorite ride! but the line is always long! having just studied potential and kinetic energy in physics, you evaluate the energy changes of the cars as they move on the tracks. Compare the potential energy of the cars if they are stopped at points A to point D.

A. Neither have potential energy.
B. The potential energy is the same.
C. Potential energy is greatest at point D.
D. Potential energy is greatest at point A. ​

Answers

C. Potential energy is stored energy, point D is taller so it has more stored energy

Potential energy is greatest at point D. Therefore, option C is correct.

What is potential energy?

Potential energy is the energy that is stored inside of an object due to the object's position, state, or arrangement. When an object's position, status, or configuration changes, the energy that has been stored in it is released.

The gravitational potential energy of an item, the elastic potential energy of a stretched spring, and the electric potential energy of an electric charge in an electric field are examples of common types of potential energy.

Potential energy depends upon the mass and height of the object. The greater the mass and height, the greater will be the potential energy of the object. The height of position D is maximum, therefore potential energy is greatest at point D. Hence, option C is correct.

Find the remainder when p(x) = –2x5 + x4 + 5x3 + 4x + 1 is divided by (x - 2).

Answers

The remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1.

To solve the question above, we make use of the remainder theorem.

Remainder Theorem: It states that if a function F(x) is divided by (x-a), the remainder is F(a).

From the question,

Given:

Dividend ⇒ p(x) = -2x⁵+x⁴+5x³+4x+1Divisor ⇒ (x-2)

in view of the above and applying the Remainder theorem, The remainder will be p(2)

p(2) = -2(2⁵)+2⁴+5(2³)+4(2)+1p(2) = -64+16+40+8+1p(2) = 1

hence the remainder when p(x) = -2x⁵+x⁴+5x³+4x+1 is divided by (x-2) is 1

There are many different kinds of microscopes. A magnifying glass is a simple microscope. The term microscope commonly refers to a compound microscope. These Microsoft are called compound because they are made of several glass lenses in a tube. The total magnifying power of a microscope is the product of the magnifying power of the lens is in the ips and the magnifying power of the lens in the objective.. Most compound microscopes can magnify a specimen up to 400 times as real size. Microscope allow you to see fine details. Space is between objects that are closer together than 0.1 mm can be seen. The ability of a microscope to separate small distances is called resolving power. If the resolving power is not good the image will be blurred. When you look into the eye piece of microscope the circular area you see is the field of view when a ruler is placed across the opening of the stage the field of view can be measured in millimeters.

Explanation:

espero ter ajudado boa noite

A submicroscopic virulent agent that infects animals, plants, bacteria etc. is called viruses. They are capable of copying inside host cells only. Viruses cause many diseases in animals and plants.

The correct discussion is:

Student A believes that viruses are not living organisms.

The student's statement can be explained as:

The virus is not capable of reproducing on its own without a host system. Therefore they cannot fit in the definition of a living organism.

They just have a genetic material encapsulated in protein coats and do have defined cell structures, unlike prokaryotes and eukaryotes.

Therefore, viruses are not contemplated to be living.

Suppose that a patient is diagnosed with a new disease caused by the buildup of waste material in the body's cells. Which organelle is most likely malfunctioning in the patient's cells?

a) Golgi apparatus.
b) lysosome.
c) ribosome.
d) endoplasmic reticulum.​

Answers

Lysosome organelle is most likely malfunctioning in the patient's cells (option b),.

The organelle most likely malfunctioning in the patient's cells is the lysosome. Lysosomes are membrane-bound organelles that contain enzymes responsible for breaking down waste materials, cellular debris, and foreign substances. They play a vital role in cellular waste disposal and recycling.

In this case, the patient is diagnosed with a disease caused by the buildup of waste material in the body's cells. This suggests that there is a problem with the breakdown and disposal of waste materials within the cells.

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for transport within or outside the cell. It is not directly involved in waste material breakdown.

Ribosomes are responsible for protein synthesis and are not directly involved in waste material breakdown either.

The endoplasmic reticulum (ER) is involved in protein synthesis, lipid metabolism, and detoxification. However, its dysfunction would not directly result in the buildup of waste material in the cells.

Therefore, considering the role of lysosomes in waste material breakdown, it is most likely that the malfunctioning organelle in the patient's cells is the lysosome. This malfunction would lead to the accumulation of waste material, causing the disease symptoms.
