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!

Help, I need advice! My in-laws are moochers!!?

Question by etsu: Help, I need advice! My in-laws are moochers!!?
I’ve been married to my husband for three years and is three months pregnant with our first child. We’re living comfortably and is trying to save money for our baby.

My father in-law lives off food stamp/ welfare, my mother in-law recently quit her part time job.. both are psychically capable and healthy but are extremely lazy! They recently took domestic trips and went on cruises, and is now planing a three-week trip to China. They’re also hoarders and are obsessed with spending money at thrift stores! (They visit Good Will store Mon-Sun and will spend up to $ 50 everyday!)

My husband has been paying for their cell phone bills for years (mother in-law is trying to get my husband to buy her an iPhone) and are now handing him bills from their car insurance to life insurance! I don’t mind my husband helping them out here and there, but they are spending thousands of dollars on trips and etc.. and is expecting my husband to pay nearly $ 500/ a month in bills for them?? I’ve talk about this to my husband but every time he refuse to help them, they will make him feel bad for not helping out or make it into something personal.

I don’t know what more I can do or say, but I feel like it is getting out of control! How can I make my husband see that his parents are simple taking advantage of him??

Answer by TiredBrainCells
Your husband is an enabler. He has no spine. I think you need to get him into counseling.

You two are married. It isn’t just his money. It is your money as well. You need to say it is time to stop. His parents are NOT NEEDY. There is no reason for a child to be supporting parents who are capable of working. Eventually, you will have to drop the bombshell – it’s either your parents or you and your child.

In addition, you might consider reporting them for welfare fraud.

~Thank you for helping me; And yes I’m very bad at geography, so I have to ask every week~
nope, i have 36 question, these are just the ones i don’t really get. >:0 thats why i need help?? hello to the person who said that?!
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)
