This question is concerned with balancing forces. First, we must consider what forces are acting on the satellites. What is stopping the satellite from shooting off into space and what is preventing it fr...

We know that the object is moving at 5m/s already telling us that the distance the object has travelled increases with time. Plotting distance on the y axis against time on the x axis we therefore expect ...

Electrons are bound to a nucleus in quantised energy levels. As they gain and lose energy they transition between this energy levels by emitting photons. Emitted photons have energies equal to the change ...

Newton’s law of gravitation states that the force of attraction between two objects due to their masses is proportional to the product of the two objects and inversely proportional to the distance between...

Molecules in the air encounter an energy source, they gain energy and begin to heat up which causes them to vibrate faster and become less dense which causes them to rise. As they rise, they begin to lose...
