The trains pass each other. cyclist is stationary when a second cyclist passes, travelling at a constant speed of 8ms! The first cyclist
then accelerates for 5s at a constant rate of 2 ms-2 before continuing at constant speed until overtaking the
second cyclist. By sketching both graphs, find the equations of the two straight-line sections of the graphs
and, hence, find how long it is before the first cyclist overtakes the second,​

Wave functions describe orbitals in a hydrogen atom. each function is characterized by 3 quantum numbers: n, l, and ml. if the value of n = 2: the quantum number l can have values from to . the total number of orbitals possible at the n = 2 energy level is .

Select the best definition for wavelength. the height of an oscillating electromagnetic wave the rate at which electromagnetic waves oscillate. the distance between two crests of an electromagnetic wave. the oscillations of electric and magnetic fields select the best definition for frequency. the oscillations of electric and magnetic fields. the height of an oscillating electromagnetic wave. the distance between two crests of an electromagnetic wave. the rate at which electromagnetic waves oscillate
