I have been given a graph with 5 squares along the x-axis and 8 squares along the y-axis, with each square 10x10 cm. The graph shows the motion of a projectile entering the graph after accelerating down a curved ramp and up again. The graph is a stroboscopic photograph of the projectile...

Gracias, thank you for your help.

Yes, that's the equation for torque. How could you rearange it to B (the magnet field). I am having trouble with equations like this one , with more than three factors. How would you rearange this one?

This is really just a matter of curiosity. Can you manipulate the torque equation of (t=nBIAcos) to find the magnetic field, B? Or do you just stick to the other formulas?

Back again, moving the equation around dosn't help because the h is inside the brackets, along with the Earth's radius (r+h). What am I missing?

Cheers, bit slow on the uptake today, but that was all I wanted to know.

Homework Statement I have to find the orbital height of a satellite with a specific g force (ie. the acceleration due to gravity). g=5.7(ms)2 Homework Equations So far I have been using the equation g=Gm/(r+h)2 to find the acceleration due to gravity, where G= gravitational...
