Em um recipiente contendo água a 100 °C, coloca-se um bloco de cobre de 200 g a 300 °C. Considerando o calor específico do cobre 0,092 cal/g°C e 540 cal/g o calor latente de vaporização da água, determine a quantidade de vapor que se formará até ser atingida a temperatura de equilíbrio térmico do sistema, sabendo que ainda restará água líquida no recipiente.

it should be -8.6 cm hope this out

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.
