At which of the following angles will the sunlight received at a location on earth spread out over the largest area? 1- 90° 2- 70° 3- 40° 4- 10°

Based on the choices provided I would go with 10 degrees.

and for anyone who comes crossed this i just want to say great job finishing mod 6 hope you do well in segment 2 exam :), flvs people know what I'm talking about ;)

a solenoid is created by wrapping a l = 90 m long wire around a hollow tube of diameter d = 4.5 cm.   the wire diameter is d = 0.9 mm.   the solenoid wire is then connected to a power supply so that a current of i = 9 a flows through the wire.

randomized variablesl = 90 m

d = 4.5 cm

d = 0.9 mm

i = 9 a                                          

write an expression for the number of turns, n, in the solenoid. you do not need to take into account the diameter of the wire in this calculation.

calculate the number of turns, n, in the solenoid.

write an expression for the length of the solenoid (l2) in terms of the diameter of the hollow tube d.

calculate the length of the solenoid (l2)   in meters.

calculate the magnitude of the magnetic field at the center of the solenoid in teslas.
