Answer the following questions in complete sentences.



A student secures a picture frame to a wall using a screw.



Part A: In terms of force, direction, and distance, explain how the screw makes the student's work easier.



Part B: Describe a change to this screw design that would make this student’s work even easier.

Answers

Answer 1

Answer:

Explanation:

A:  Screws are a simple machine that make doing work easier.

Work = W = Fd

F = W/d

So by increasing distance (d), you decrease the amount Force needed to do the work.

By applying a small rotational force (circular direction) on the screw, the axial force is amplified.  It takes less force to turn a screw around than to drive a nail straight into the wall.

B:  To make the job even easier, choose a screw with a "finer" thread.  The smaller the pitch (the distance between the screw's threads), the greater the mechanical advantage (the ratio of output to input force).  

Answer 2

Part A: The screw makes the student's work easier by providing a force that is directed downwards into the wall, allowing the student to secure the picture frame in place with a relatively small distance of travel.

What is force?

Force is a physical quantity that is defined as the product of mass and acceleration. It is a vector quantity, meaning it has both magnitude and direction. Force is one of the fundamental concepts of physics and is responsible for the motion of objects. It is also responsible for the interaction between objects, such as the force of gravity that keeps the planets in orbit around the sun. Force can be applied to objects in order to cause them to move, accelerate, decelerate, or change direction. Force can also be used to do work, such as lifting a weight or pushing a car. Force is an important concept in physics and is used to explain many phenomena in the natural world.

Part B: A change to the screw design that would make the student's work even easier would be to use a self-tapping screw, which has a sharp point that allows it to cut its own thread into the wall, eliminating the need to pre-drill a hole. This would reduce the amount of effort required to secure the picture frame to the wall.

Edwin hubble was able to show that (with the exception of our nearest neighbors) the farther a galaxy is from us, the faster it is moving away from us.

Hubble ultimately demonstrated that, contrary to the widely accepted belief that the universe is static, galaxies are actually moving away from us. Hubble noticed that the light appeared to be shifted toward the red end of the spectrum by observing the light coming from distinct galaxies.

Hubble made the amazing discovery that a galaxy's redshift exactly correlated with its distance from the earth. That implied that objects farther from Earth were dispersing more quickly. To put it another way, the cosmos must be growing. In 1929, he made his discovery public.

A force of 50 n is used to push a wheelchair forward at constant velocity. if the wheelchair is displaced 0.5 m each second, what is the mechanical power expended when transporting the wheelchair?

Answers

The mechanical power expended when transporting the wheelchair is 25 Watts

What is power?

Power is defined as  the amount of energy transferred or converted per unit time. The unit of power is measured in Watts. The higher units are kilowatts, megawatts etc.

The formula for calculating the power expended is expressed as:

Power = Workdone/Time

Since workdone = force * distance, the formula for power will be:

Power = Force*distance/Time

Given the following parameters

Force = 50N

distance = 0.5m

time = 1 second

Substitute to determine the power

Power = 50*0.5/1

Power = 25/1

Power = 25Watts

Generally, a gas molecule is simply defined as a combination of numbers of atoms that are connected one to another.

here, 10 m/33 feet of sea water is taken to exerts a gauge pressure that is the same pressure as the atmosphere.

This means that we add one atmosphere/bar pressure for every 10 m/33 feet you descend.

The effect of this is that,

at 10 m/33 ft absolute pressure is two ata/bar

Adding another 10 m/33 ft to this depth to make it 20 m/66 ft, puts you under under three ata/bar of pressure and so on.

Descending to a depth it means that you have double the ata/bar pressure acting on you. If you decide to resurface, the pressure on the flexible container will reduce by a factor of two.

Nucleotides are organic compounds made up of a phosphate and a nucleoside.They function as monomeric units of the key macromolecules found in all living forms on Earth, deoxyribonucleic acid (DNA), and ribonucleic acid (RNA), which are both nucleic acid polymers. In addition to being produced by the liver from common nutrients, nucleotides can also be received through diet. A nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group made up of one to three phosphates are the three component molecules that make up a nucleotide. Guanine, adenine, cytosine, and thymine are the four nucleobases found in DNA; uracil is used in place of thymine in RNA.On a fundamental, biological level, nucleotides are also essential to metabolism. They supply chemical energy throughout the cell in the form of the nucleoside triphosphates adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP), and uridine triphosphate (UTP).These are necessary for the synthesis of amino acids, proteins, and cell membranes as well as for moving the cell and its components (both internally and between cells), cell division, and other cellular processes.Nucleotides are also key cofactors in enzyme activities and take role in cell signaling (cyclic guanosine monophosphate, or cGMP, and cyclic adenosine monophosphate, or cAMP).
