Question 8 1.5 pts A current carrying solenoid has a current of 30 A, loops around 700 times and has a magnetic field of 7.62 *10^-2 T inside it. What is the length of the solenoid? Ho = 4n *10^-7 T*m/A 2.0 cm O 0.31 cm 34.6 cm 0.29 cm Question 9 1.5 pts A laser, starting in air, is shined onto a glass panel. As the laser is passing into a glass panel, it has an angle of refraction of 17. What was the angle of incidence of the laser on the glass, if the glass has an index of refraction of 1.55. (Index of refraction of air can be treated as 1, and numerical answer given is assumed to be in units of degrees)
