Which sentence is an example of an informative claim? a. it is the government's responsibility to ensure that all students receive a proper education. b. the cost of a college education should be affordable to everyone, not just the wealthy. c. students should choose a college based only on the rigorousness of academic programs. d. colleges such as harvard and princeton have long been considered the best in the country.

Yeah It's D you were wrong

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.

explanation:

the correct answer is:   [d]:   " diagram "   .

hope this !

    best wishes to you!
