Two radio antennas are separated by 1.60 mm . Both broadcast identical 750 MHz waves.
Part A) If you walk around the antennas in a circle of radius 10.0 mm , how many maxima will you detect?

20

Explanation:

Given the following information:

Expression for path difference is given as:

And for wavelength as:

#substitute the values for wavelength:

#Substituting the values for the ratio of distance to the wavelength;

Hence,

#there are total number of 4 meeting points for maximum constructive interference. Therefore, total number of maxima points are 5×4=20.

explanation: in any substance/object, the particles inside it (atoms/molecules) constantly move in random directions and with random speeds (this motion is called brownian motion). as a result, the particles have some kinetic energy (which is proportional to the temperature of the substance).

explanation:

have a great day!

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.
