explain why is there no work in the following:
1. carrying a 15-kg backpack as you walk a horizontal distance of 50 m
2. pushing against a stationary wall for a long time
3.carrying a box inside a tricycle
Answer:
Explanation:
Well, this is one of those physics questions that relies heavily upon technicalities.
Something to remember is work is determined by force*distance.
1. When you are carrying a 15kg backpack, the weight or the backpack itself is quite indifferent. This is because the backpack is moving relative to you, so the backpack isn't doing diddly squat itself. The only force being exerted is yourself against the ground and vice versa because of gravity and Newton's Law, but when you have a horizontal distance (not vertical), the direction of your motion is 90 degrees to the exerted force. When you calculate this out using the formula and cos(90), you'll find the answer is technically 0.
If it were vertically, this'd be different.
2. Again, wording is important. Work is Force times DISTANCE. Key word in this situation, DISTANCE! When you push against a stationary wall (stationary as in, the wall "can do this all day" whereas you definitely can't), you're exerting a force against an object that really, really doesn't want to be moved. Walls in of themselves are MADE to not be moved, that's why they are walls. So, any force you exert is going to get multiplied by a distance of 0, and as we should know from basic times table charts, anything multiplied by 0 will ALWAYS be 0.
So, again, there's technically no WORK done, according to physics. Because again, work is a product of force and distance. So push harder, ya lazy good for nothin weakling!!
3. You can carry anything you want inside a vehicle, it doesn't mean there's any force being done. YOU'RE not doing squat, the vehicle itself is. In a tricycle, if the box is on the tricycle and not affecting you in any way, then there is no force being done despite an obviously moving distance.
By physics definition, there's EFFORT, but no WORK.
Hope this helps a little :)

What is the role of DNA and chromosomes in coding the instructions of traits passed from parent to offspring?
Answer:
Genes are regions in the DNA that contain the instructions that code for the formation of proteins. Each chromosome consists of a single, very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species' characteristics are carried in the DNA.

After the cell cycle was discovered, scientists found a protein that regulates the cycle. They have since found many more proteins involved in the regulatory process. Scientists are using this information to learn more about cancer. Which phrase describes cancer a. Uncontrolled cell growth b. Bent and twisted red blood cells c. An abnormal number of chromosomes d. Lipid accumulation in brain cells
Answer:
a. Uncontrolled cell growth
Explanation:
Cancer is an irregularity that occurs when cells mutate in a harmful way. This causes abnormal cell growth that is uncontrollable. These cell growths become tumors that, based on the type, may or may not spread to other parts of the body.
Answer:
A. Uncontrolled cell growth
Explanation:
When cancer enters the body, the cells divide rapidly and without a stop, and it also destroys your body tissue.
A bus changes its velocity from 5 m/s to 15 m/s in 5 seconds. What is its acceleration?
A 2 m/s2
B 5 m/s2
C 25 m/s2
D) 75 m/s2
Answer:
[tex]\boxed {\boxed {\sf A. \ 2 \ m/s^2}}[/tex]
Explanation:
Acceleration is the rate of velocity's change with time.
We can calculate it by dividing the change in velocity over time.
[tex]a=\frac{v_f-v_i}{t}[/tex]
Let's define the variables. The final velocity is 15 meters per second. The initial velocity is 5 meters per second. The time is 5 seconds.
[tex]v_f= 15 \ m/s \\v_i= 5 \ m/s \\t= 5 \ s[/tex]
Substitute the values into the formula.
[tex]a=\frac{15 \ m/s- 5 \ m/s}{5 \ s }[/tex]
Solve the numerator first.
15 m/s - 5 m/s= 10 m/s[tex]a=\frac{10 \ m/s}{5 \ s}[/tex]
Divide.
[tex]a= 2 \ m/s/s = 2 \ m/s^2[/tex]
The acceleration of the bus is 2 meters per second squared.

other organelles through the
A) secretory pathway
B)photosynthesis
C)nucleus
Answer:
A
Explanation:
The proteins modified in the rough ER move to the Golgi Apparatus and other organelles through the process of the secretory pathway.
What do you mean by Golgi apparatus?
Golgi apparatus may be defined as a cell organelle that is responsible for protein synthesis. It is present in between the ER and plasma membrane.
The secretory pathway reveals the transport of proteins through rough ER to Golgi apparatus, lysosomes, and plasma membrane.
It involves the action of spherical-shaped vesicles that helps in the movement of proteins.
Therefore, the proteins modified in the rough ER move to the Golgi Apparatus and other organelles through the process of the secretory pathway.

Can anyone help me, I have to write a scientific report on recycling but I don't know how to write it, please help me
Plz zzzzzzzzz....
Answer:
Searching For Facts
You must first begin surfacing the net or other sources for facts about the Topic provided.It also quite depends on the size of the scientific report you are preparing. (It is usually large about 4000 words).If you are abundant with information, about the topic, write To-The-Point. If there is a lack of information, try to expand about a sub-topic whilst including new facts about the same.Constructing a report:
You can start with an appropriate title about your topic, just ensure that it doesn't go too long. Begin the report with a short introduction about the report. If you are noting an experiment, include the apparatus required.The body should provide a detailed description about the topic. You may use tables or paste images in the report.If it's a report about an experiment, don't forget to write down the observations.Lastly, a conclusion with a brief thought derived, must be included in the report.If necessary, attach the References in the report too.A student creates a diagram showing a scale representation of the planets in the solar system.

The cytoplasm of a cell is at ph7 and the interior of an organelle is ph8
A. What is the quantitative relationship between the number of hydrogen ions present at pH 7 versus pH 8?
B. Using your knowledge of transport in cells, what is a possible mechanism for how the cytoplasm would have a lower pH than inside the organelle?
A pH=-log(10)[H+], from this formula we can deduct that when the number of protons is higher the pH is lower and when the number of protons is lower the pH is higher. This means there are more hydrogen ions in the cytoplasm compared to the inside of an organelle.
B Hydrogen ions are very small particles so they can easily diffuse through the plasma membrane inside the cytoplasm, resulting in a higher number of protons and a lower pH. Organelle membranes have a lower permeability for hydrogen protons so the pH is higher.
