17N.2.HL.TZ0.b.i
There is a proposal to power a space satellite X as it orbits the Earth. In this model, X is connected by an electronically-conducting cable to another smaller satellite Y.
Satellite Y orbits closer to the centre of Earth than satellite X. Outline why
the orbital times for X and Y are different.
[1]
Markscheme
Y has smaller orbit/orbital speed is greater so time period is less
Allow answer from appropriate equation
Allow converse argument for X
