A jogger runs at a constant rate of 10.0 m every 2.0 seconds. The jogger starts at the origin and runs in the positive direction for 3600.0 seconds. Hint: Draw a position- time graph.
a. Where is the runner at time t= 5.0 s?
b. Where is the runner at time t= 15.0 s?

Answers

Answer 1

Answer:

(a) 25 m

(b) 75 m

Explanation:

Given that the jogger runs at a constant rate of 10.0 m every 2.0 seconds.

So, the speed of the jogger,

[tex]v=\frac{10}{2}=5m/s\;\cdots(i)[/tex]

Let d be the distance covered by him in time, t s.

As distance=(speed) x (time)

So, [tex]d=vt[/tex]

From equation (i)

[tex]\Rightarrow d=5t\;\cdots(ii)[/tex]

As the jogger starts from origin, so, the distance, [tex]d[/tex], also represents the position of the jogger at the time [tex]t[/tex] s.

The position-time graph has been shown.

(a) From equation (ii), for t=5.0 s

[tex]d=5\times 5=25 m[/tex]

So, the jogger is at a distance of 25 m from the origin.

(b) Similarly, for t=15.0 s

[tex]d=5\times 15=75 m[/tex]

So, the jogger is at a distance of 75 m from the origin.

Explain what the interviewer meant when he said that genetic mutations are like misprints in a book.

Answers

Answer:

A publisher can misprint a book in several different ways. The publisher can miss words, make spelling errors, mix up paragraphs, or delete some text entirely. With such errors, the text will be inaccurate, and people reading that part will get confused. Mutations in genes happen similarly. At times, parts of the gene may change entirely, leading to altered products. There are many types of gene mutations, but all types of mutations can potentially affect the cell and its function.

From fastest to slowest, rank the speeds of the balls 1 s after being thrown. Rank the speeds of the balls from fastest to slowest. To rank items as equivalent, overlap them. Three balls of different masses are thrown straight upward with initial speeds as indicated: PICTURE

rank speeds
rank acclerations

Answers

Explanation:

From the given figure,

Mass of ball A is 4.9 kg and its initial speed is 8 m/s.

Mass of ball B is 1.9 kg and its initial speed is 14 m/s.

Mass of ball C is 0.7 kg and its initial speed is 2 m/s.

We need to find the final speed of the balls 1 s after being thrown. They all are thrown upward under the action of gravity. The equation of motion is : v = u -gt, g = 10 m/s²

For ball A,

v = 8-10(1) = = -2 m/s (downward)

For B,

v = 14-10(1) = 4 m/s (upward)

For C,

v = 2-10(1) = -8 m/s (downward)

It means the ranking is B>A>C i.e. the speed of ball B is the most and that of C is least.

All the balls are moving under the action of gravity. It would mean that the acceleration for all balls is same i.e. 10 m/s²

Explanation:

Balanced forces acting on an object
O Always change the object's motion.
O Sometimes change the object's motion.
O Never change the object's motion.
O Are not related to motion.

Answers

Sometime is the answer... hope I’ve help y’all

Answer:

Balanced forces do not change the motion of an object. The motion of an object will not change if the forces pushing or pulling the object are balanced. An object that is sitting still will stay still if the forces acting on it are balanced

Explanation:

When two forces acting on an object are equal in size but act in opposite directions, we say that they are balanced forces . If the forces on an object are balanced (or if there are no forces acting on it), this is what happens: ... a moving object continues to move at the same speed and in the same direction.

1. Do you think your memories can be altered? Explain

Answers

Answer:

Yes

Explanation:

I think our memories can be altered by emotions. If someone tells you something over and over and over again with strong emotion you will start to remember that more than the memory.

Emotions are very powerful and if you feel a certain emotion connected with a different memory I think that is stronger and can trick your brain into thinking that is the memory because of the strong emotion, even though the true memory was right, since it might not have as strong of mental emotion your brain will think that is the false memory because whatever is more memorable your brain will remember.

A gas has a pressure of 0.470 atm at 60.0°C. What is the pressure at standard temperature? Round your answer to the nearest thousandth

Answers

Answer:

P2=0.385atm

Explanation:

step one:

Given that the temperature T1=  60 Celcius

we can convert this to kelvin by adding 273k to 60 Celcius

we have T1= 333k

pressure P1= 0.470 atm

step two:

we know that the standard temperature is T2= 273K

Applying the temperature and pressure relationship we have

P1/T1=P2/T2

substituting our given data we have

0.47/333=P2/273

cross multiply we have

P2= (0.47*273)/333

P2= 128.31/333

P2=0.385 atm

PLEASE HELP THIS IS DUE TODAY If an element's atomic mass and atomic number are known, what else can be determined? Give an example to demonstrate your understanding.

Answers

If you know an element’s atomic number, you will learn the number of protons and electrons. The atomic number is equal to the number or protons and electrons. You can also find the number of neutrons, by subtracting the atomic mass from the atomic number.

For example, Fluorine’s atomic number is 9, and its atomic mass is 19. So, the number of electrons and protons in fluorine is 9. The number of neutrons the is equal to 19-9. Thus, Fluorine has 10 neutrons.

C. A model can be used for things that are too small to see clearly.
D. A model can be used for things that are too hot to handle easily.

Answers

Answer: I think it’s C.

Explanation:

The correct answer is C

Scientific Models are lay down processes or ideas toward achieving a specific goal. It can be mathematical in nature, or conceptual representation.

In most cases, scientific model are employed for complex findings or experiments. In this scenario, the plant cell is complex to study in the sense that the cells can not be seen with our naked eyes.

Therefore, the scientist will use a physical model of a plant cell instead of studying  a cell directly because  a model can be used for things that are too small to see clearly.

If a distance versus time graph is flat, what does that say about the velocity at that time?

Answer:

In either case, the curved line of changing slope is a sign of accelerated motion (i.e., changing velocity). Applying the principle of slope to the graph on the left, one would conclude that the object depicted by the graph is moving with a negative velocity (since the slope is negative ).
