How do you describe a circus? i have to write an essay about two boys who are afraid of clowns, so they go to a circus to overcome their fear and then, in the end, find out the cl0wns were friendly.

Explanation:

If they are enjoying the circus it should be fun and colorful most circuses have animals and some have trapeze hanging from the ceiling/tent some have tightropes. They might have lion tamers. The circus could be loud. Maybe it is small. or crowded. Or maybe The boys think the clown is great. Maybe they focus mainly on the clowns at this circus?

i think the answer is d.

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.
