A jet engine emits sound uniformly in all directions, radiating an acoustic power of 3.77 × 10 5 W. Find the intensity of the sound at a distance of 46.1 m from the engine

Explanation:

Given that:

acoustic power (P)= 3.77 × 10⁵ W

Find the intensity of the sound at a distance of 46.1 m from the engine

The distance (i.e the radius) = 46.1 m

The relation can used to find the intensity of the sound from the engine.

Substituting our values, we have:

i was thinking more like reflects green light, just not sure

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.
