What of the following statements would you read with a tone of surprise? a. " hurry down the stairs." b. ", i cannot reach the phone." c. "can you believe lulu the pug unlatched the gate? " d. "michael and roselle escaped safely."

C). "Can you believe LuLu the pug unlatched the gate?"

This statement is read with a tone of surprise. This is because of the first few words of the sentence: "Can you believe..." This implies that the speaker is shocked/surprised by what they are saying, giving this statement a tone of surprise.

not sure how to answer your question sorry

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.
