Energy Potential Potential energy

AI Thread Summary

To calculate the energy required to move a satellite from an altitude of 1RE to 3RE, one must determine the gravitational potential energy (GPE) at both altitudes. The total energy for a satellite in orbit includes both kinetic and potential energy, and the energy difference between the two orbits will provide the required energy for the move. The user is struggling with the calculations and seeks clarification on the correct approach to find the GPE values. Understanding the relationship between altitude and gravitational potential energy is crucial for solving the problem. Accurate calculations will yield the necessary energy for the satellite's transition between orbits.

What's the total energy for a satellite in orbit? Then simply find the energy difference between the two orbits.

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...

Thread 'Explain this asphalt sheen'

This problem is two parts. The first is to determine what effects are being provided by each of the elements - 1) the window panes; 2) the asphalt surface. My answer to that is The second part of the problem is exactly why you get this affect. And one more spoiler:
