Nasa communicates with the space shuttle and international space station using ku-band microwave radio. suppose nasa transmits a microwave signal to the international; space station using radio waves with a frequency of 18.0 ghz. what is the wavelength of these radio waves?

0.0167 m

Explanation:

f = Frequency = 18 GHz

c = Speed of light =

When the speed of the wave is divided by the freqeuncy we get the wavelength

Wavelength is given by

The wavelength of the radio waves is 0.0167 m

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.
