Physics Questions about Newton’s Laws Help?

Question by Wyatt~: Physics Questions about Newton’s Laws Help?
I just have around 7 basic questions about Newton’s Laws.
Please explain them, and Solve them, Because I am clueless.

1. Which law is in control of a spacecraft which cruises through space at a constant speed without using any fuel?

2. Which law governs when a tablecloth is pulled out from under a setting of china without damaging it?

3. Which law governs why a car is set in motion and not the asphalt highway on which it travels?

4. Which law allows a spaceship to accelerate by burning rocket fuel?

5. Which law relates acceleration to mass?

6. Which law governs when two skaters push apart in a rink?

7. Which law governs why a golf ball will go farther than a baseball if each are hit with the same amount of force?

Best answer:

Answer by Physica Mathematica
1. Which law is in control of a spacecraft which cruises through space at a constant speed without using any fuel?

Newton’s First Law- object in motion (straight line) stays in motion

2. Which law governs when a tablecloth is pulled out from under a setting of china without damaging it?

Newton’s First Law- objects at rest tend to stay at rest

3. Which law governs why a car is set in motion and not the asphalt highway on which it travels?

Actually the problem is flawed. For the most part the car moves forward over the road, but to a very slight extent the highway moves backwards under the car (Newton’s Third Law)

4. Which law allows a spaceship to accelerate by burning rocket fuel?

Newton’s Second Law – Force = mass times acceleration

5. Which law relates acceleration to mass?

Newton’s Second Law – Force = mass times acceleration

6. Which law governs when two skaters push apart in a rink?

Newton’s Third Law – for every force or action there is a force or reaction in the opposite direction of equal magnitude– they should have worded this more carefully, and said something like “if one of the ice skaters pushes against the other, they both move opposite one to the other.
To some extent we should mention Newton’s Second Law because although both get the same force, the one with less mass will accelerate more than the other.

7. Which law governs why a golf ball will go farther than a baseball if each are hit with the same amount of force?

Newton’s Second Law – Force equals mass times acceleration

To some extent this exercise could be a problem. Although I feel I captured the intent, a student might leave this thinking that different “Newton Laws” apply to different problems.

All 3 laws are always in play — they don’t “pick and choose” or “take turns”.

Cheers!

Thank you so much for helping me, it’s just that there’s always a few questions i don’t know for my study guide, thanks to you, I’m able to complete it, yay! ^^

Best answer:

Answer by critters
1. Brasilia
2. Canada
3. cardinal: north, south, east, and west; intermediate: northeast, northwest, southeast and southwest
4. Brazil, Bolivia, Paraguay, and Chile
5. Nile – Africa, Amazon – South America, Ob-Irtysh – Asia and Chang Jiang – Asia
6. east of 80° – it is 76° 55’°W
7. Norway is 12 people per KM, Italy is 196.1 /KM Norway is lower by far – reason Protestant with 82.7 % (more practice of bith control – family size is 1.4 children
http://www.demographic-research.org/volumes/vol10/10/10-10.pdf
Italy – Catholics make up for the 87.8% – have in the past had more children on average – generally family size in urban areas is 1.4 however in rural areas it is 4.0
http://www.unece.org/pau/_docs/pau/1998/PAU_1998_RPM_CntrReprtITA.pdf

– Italy has a better climate – maybe less people emigrate to another country – or perhaps more people who have emigrated return home when they are ready to retire (cheaper to purchase land/homes/to live)

I have two students on F1 visas living with me and they have questions.?

Question by Ffion: I have two students on F1 visas living with me and they have questions.?
They are on a F1 visa with a I20 for high school. They are both 18. They are both from China and one wants to open an E-Trade account. She does not have a SSN or TIN. She has a bank account that is it.
The other wants to take a cruise to Mexico. Can he actually leave the USA?

Best answer:

Answer by Fred S
A cruise to Mexico would be easy enough to accomplish if the student takes a valid passport and a properly endorsed SEVIS I-20 form.

It could be a current SEVIS Form I-20 properly endorsed by the DSO for reentry if there has been no substantive change to the most recent Form I-20 information, or a new SEVIS Form I-20 if there has been a substantive change in the information on the student’s most recent Form I-20 information, such as in the case of a student who has changed the major area of study, who intends to transfer to another Service approved institution or who has advanced to a higher level of study.

He would need to be returning to the U.S. to attend school. Remember, high school students are limited to 12 months of study at a public high school.

The E-Trade question isn’t really an immigration question. A stock broker or the Social Security administration can answer that one.
