What is the 2 answer for -3√7+4√7

2.6

In addition, in continuing our partnership with LCTV, we are also very close to having all the necessary components in place to livestream our meetings for those who would prefer to watch from home,” Wydysh said. “If that is not in place for the Aug. 4 meeting, then the meeting will be recorded and available on-demand from LCTV and the county’s communication channels the next day

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.

explanation:

54 degrees incident angle = reflected angle

angle is from normal turned to line of ray
