In “Superhero 101: A Family Secret,” Trace misses his grandmother's birthday party and visits her to apologize. How does this incident provoke Trace's grandmother to make a decision?

She's afraid to reveal how his grandfather really felt about him.

She doesn't want to have to tell him lies about his parents' deaths.

She doesn't want him to share his secret identity with his friends.

She tells him that she already knows about his superpowers.

Im not 100% sure but i think its B.

the correct answer would be:  

a. adverb phrase

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.
