Which statement is an example of a theme?

a. ben wanted to be a star basketball player, so he spent many long nights in the gym practicing his skills.
b. ben doesn't make the basketball team on his first try but he works hard and makes the team next year.
c. it's important to never give up on your dream, no matter how hard the sacrifice and struggle.
d. a boy works hard to become good at basketball and is rewarded with high praise and a scholarship.

C would be it. It is showing ton never give up which can be a theme.

D. It's important to never give up on your dream, no matter how hard the sacrifice and struggle.

Explanation:

what is the context here? we need to know what story you're 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.
