Pls help i dont have the articel pls help i dont know this 1. Lines 1–13: Who is Kennedy’s audience for this speech? What is Kennedy’s likely purpose? Which words hint at this purpose?

2. Lines 31–42: Find the lines in which Kennedy states his claim. Restate the claim in your own words.

3. Lines 43–55: What is the first reason Kennedy uses to prove his claim? What evidence does he provide for support?

4. Lines 56–72: Explain how the second reason Kennedy uses to prove his claim differs from the first reason.

5. Lines 79–88: What counterargument does Kennedy give here?

6. Considering the audience and purpose of Kennedy’s speech is his argument convincing? Do you believe American’s should support the space program based on his evidence?

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.
