ANSWER THIS QUESTION PLS WILL GIVE BRAINLEST A star has right ascension of 5 hours. Which of these statements is correct about the star?

It is 5 hours to the west of zero hours right ascension.
It is 5 hours to the east of zero hours right ascension.
It is 5 hours north of the celestial equator.
It is 5 hours south of the celestial equator.

A

Explanation:

It is 35 minutes to the east of zero-hours right ascension. Explanation: The right ascension of a star basically determines the position of the star on the east to west co-ordinates system.

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.
