When two plane mirrors are kept at an angle of 60 degrees , how many images are formed? Related to Subject Physics
Need Solution with All the steps​

5

Explanation:

Using the formula

Number of images = 360/theta - 1

theta is the angle of inclination

Given

Theta = 60°

Substitute

Number of images = 360/60 -1

Number of images = 6-1

Number of images = 5

Hence the number of images formed is 5

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.
