Problems 2-A 900W microwave generator in an oven generates energy quanta of frequency 2560 MHz (a) How many energy quanta does it erit per second? (b) How many energy quanta must be
absorbed by a pasta desh placed in the radiation cavity to increase its temperature by 45K? Assume
that the dish has a mass of 0.5kg and that its specific heat is 0.9 kcal/kg. K. (c) Assume that all energy
quanta emitted by the generator are absorbed by the pasta dish. How long must we wait until the
dish is (b) is ready?

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.

the answer is mosques. they are an important part of islamic culture.

i think it would be 5
