A cyclist traveling in a straight line has the velocity of +5 m/s for 10 sec. She then accelerates at a rate of 0.5 m/s2 over another 10 sec. How far does the cyclist travel during those 20 sec?

125

Explanation: use the equation d=vt to find the first distance, 50. Then use the equation

X=Vot + 1/2at to find the second distance. Then add both together.

Vo=5

V=5

T=10

A=5

absorption lines are where light has been absorbed by the atom thus you see a dip in the spectrum whereas.

emission spectra have spikes in the spectra due to atoms releasing photons at those wavelengths.
