Which of these statements suggests that the orbital period of venus is shorter than that of saturn?
a) saturn is much larger in size than venus.
b) saturn is a gaseous planet; venus is not.
c) venus is closer to the sun than saturn is.
d) saturn takes less time than venus to complete one rotation on its axis.

C)Venus is closer to the Sun than Saturn is.

Explanation:

This is the right answer.

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

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.
