Change in gravitational field strength

AI Thread Summary
The discussion revolves around calculating the change in gravitational field strength from sea level to the top of Mont Blanc, which is 4807 m high. The gravitational field strength at sea level is given as 9.826 N/kg, and participants express confusion about how to approach the problem. They discuss the need to apply Newton's law of universal gravitation, which involves the mass of the Earth and the distance from its center. One participant emphasizes the importance of attempting the problem independently rather than seeking direct answers. The conversation highlights the challenges of understanding introductory physics concepts in an online learning environment.

Homework Statement


The tallest spot on Earth is Mt. Everest. But another well-known mountain is the Mont Blanc, European Alps, which is 4807 m above sea level. If the radius of the Earth to sea level is 6367 km, how much does the gravitational field strength change between the sea level value at that location (9.826 N/kg) and the top of the Mont Blanc?




The Attempt at a Solution



I don't even know how to begin. :-(

What is the equation for the force of gravity, in terms of the mass of the Earth, the mass of whatever you're weighing, and the distance between the two centers of mass? It has a big "G" constant in it as well...
 
I have no idea. I am supposed to be in an introductory course and it doesn't seem to be that way. On top of that it's an online course.
 
Thank you! But, I'm still confused. How do I set it up? Once I get it setup I can solve it.

Nope. You need to do the work, leslie. We don't do your homework for you. You wouldn't be learning if we showed you the relevant equations and set everything up for you.

Re-read the question, and read the link that I provided, and think through how you can use that equation for this problem. Show us your work and we can try to help more.

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
