An airplane flying at a velocity of 610 m/s lands and comes to a complete stop over a 53 second period. a. Did this airplane speed up or slow down? Explain your reasoning. b. Did this airplane accelerate or decelerate? Explain your reasoning. c. Should your answer be positive or negative? Explain your reasoning. d. Calculate the acceleration.

Answers

Answer 1

Answer:

the airplane slowed down; it came to a stop over 53 seconds, which requires slowing. the airplane decelerated; decelerate is another word for slow down, it also is the opposite of accelerate.  The answer should be negative; negative velocity is slowing down. And the acceleration is ~ -11.509 meters every second

Explanation:

the explanations are included in the answer.

Answer 2

Answer:

A) The airplane slowed down. It states that the plane lands and come to a complete stop over a 53 second period.

B) It decelerates. The speed doesn't increase. It slows down.

C) The answer should be positive. Although the deceleration is slowing down the plane, it's not going at a negative speed.

D) The answer is 11.5m/s. I divided the velocity by the amount of seconds it takes to make a complete stop.

Pleiotropy is a tough word, not going to lie. It really just means that one gene can control several different traits. Marfan syndrome is an example of a genetic disorder where the presence of one gene causes many different traits to appear. Some evidence suggests that President Abraham Lincoln could have had Marfan's, but the absolute best example (in my opinion) is Peter Mayhew (the original actor that played Chewbacca!) who was over 7 feet tall! What are some (list at least 3) of the phenotypic traits for an individual who has the Marfan genotype?

Which of these correctly relates the photoreceptor to the region of the brain to which it connects? Photoreceptor connects to visual region

What is photoreceptor ?

Photoreceptors can be defined as cells for detecting light. They are composed of the outer nuclear layer that contains the cell nuclei the inner segment that houses the cell machinery and the outer segment that contains photo-sensitive pigment.

Therefore photoreceptors are the only cells that can convert incoming light into an electrical signal that can be carried to the brain via the optic nerve to create conscious vision.

An offshore oil platform houses a drill for drilling oil. The drill descends from the platform and enters the ocean. At the bottom of the ocean, the
drill starts to dig into the rock. It continues drilling into the rock for another 7,000 feet and then stops. Where does the drill stop?

in the biosphere
in the geosphere
in the atmosphere
in the hydrosphere

Answers

Answer:

in the geosphere

Explanation:

The drill will eventually stop within the geosphere.

The biosphere is the region of the earth populated by living organisms. The geosphere is the region of the earth made up of solid rock The atmosphere is the gaseous part of the earth. The hydrosphere is the liquid part of the earth or where water dominates the earth.

The drill pierces through the geosphere as it initially passes through the hydrosphere. Eventually, the drill stops within the geosphere.

WHY DOES WATER HAVE A HIGH SPECIFIC HEAT? WHAT IS THE SPECIFIC HEAT OF WATER?

Answers

Answer:

Depends on the temperature of it's surroundings.

Explanation:

Answer:

There are two reasons. One of them is that the water molecule is “bent”. It is rotationally asymmetric, meaning that it can “store” more energy in the rotational degrees of freedom than other, symmetric molecules (like diatomic molecules, or CO 2  for example).

The other and more important reason are the hydrogen bonds. When a hydrogen atoms binds with a more electronegative atom (such as oxygen in the case of water), its electron has a higher probability to be found in the vicinity of the oxygen atom, leaving the hydrogen nucleus partly “exposed”. This partial charge on the hydrogen will create a very weak bond with the partly negatively charged oxygen atom of a neighbouring water molecule (remember, the hydrogens’ electrons prefer to be around the oxygen atom instead, making it a bit negatively charged). This electrostatic interaction, or bond, between neighbouring water molecules is the famous hydrogen bond.

Even though each hydrogen bond by itself is weak compared to the bonds in the molecules themselves, there are many neighbours around each water molecule, which means that water can store a significant amount of energy in these bonds. As you add heat to water, instead of speeding up the molecules (increasing their kinetic energy and thus temperature) the hydrogen bonds get broken up, soaking in the additional heat without much change in temperature.

Which type of energy do muscle cells use to produce mechanical energy in the movement of an arm?

Answers

Answer:

usually in association with myosin, are responsible for many types of cell movements. Myosin is the prototype of a molecular motor—a protein that converts chemical energy in the form of ATP to mechanical energy, thus generating force and movement.

Explanation:

The type of energy muscle cells use to produce mechanical energy in the movement of an arm is known as chemical energy.

Which type of energy do muscle cells use?

The type of energy that muscle cells use is known as chemical energy. Adenosine triphosphate (ATP) is the energy source for all muscle contractions. Energy is released when ATP is broken into ADP+Pi (adenosine diphosphate and phosphate group).

Maintaining the availability of ATP for muscle contraction is the limiting factor since ATP is not stored in large amounts in skeletal muscle. Muscle contraction converts chemical energy to mechanical energy when ATP is hydrolyzed during cross-bridge cycling.

This mechanical energy is then distributed and stored in the tissue as the muscle deforms or is used to perform external work.

Therefore, chemical energy is the type of energy muscle cells use to produce mechanical energy in the movement of an arm.
