An electron in the ground state of hydrogen absorbs a photon with wavelength 103 nm, and ends up in a state described by quantum numbers n, l, m_l, m_s. Which of the following is not a possible value for these quantum numbers? a. I=3
b. m_l=2
c. m_l=0
d. I=0
e. m s=-1/2

The particle p starts from rest at point a at time t = 0 and changes its speed thereafter at a constant rate of 2.8g as it follows the horizontal path shown. determine the magnitude and direction of its total acceleration (a) just before point b, (b) just after point b, and (c) as it passes point c. state your directions relative to the x-axis shown (ccw positive) and choose the angle with the smallest magnitude.
