Hello, Tomorrow we're taking a physics test on carbon burning and helium burning. I have no idea what that is or how to describe it. One lesson ago, we looked at hydrogen burning and were shown the image below. The blue boxes next to it are supposed to describe it, but half of the description…
Could you please help me with these tasks? 1) A satellite orbits the Earth at a speed of 0.99 c. Calculate how much time passes for the satellite when 10 y pass on Earth. State the equation t = … that you used. 2) An observer on Earth sees a spaceship passing by at a…
Yeah, the question is above. It's about the standard 9V power supplies.
Will you end up in space at some point?
How can the difference between the speed of current and electrons be explained

I’m not sure how the question is meant. One could reduce the current through coil 1, then a magnetic field is induced in coil 2 according to Lenzscher rule, which is opposed to the decrease in the field in coil 1. The currents in coil 1 and 2 are then in the same direction and the coils are drawn.
It is, however, more likely to mean that the deflection can be reduced by replacing (1) the coil core with a lower permeability. the coil core is removed at all or (2) by reducing the number of turns of the coil 1.
