Gwhat is the specific heat of silver? the molar heat capacity of silver is 25.35 j/mol⋅∘c. how much energy would it take to raise the temperature of 9.00 g of silver by 18.3 ∘c? express your answer with the appropriate units.

38.6 J

Explanation:

c = molar heat capacity of silver = 25.35 J/(mol °C)

m = given mass of silver = 9.00 g

M = Molar mass of silver = 108 g

n = Number of moles of silver

Number of moles of silver are given as

n = 0.0833

Q = Energy needed to raise the temperature

ΔT = Change in temperature = 18.3 °C

Energy needed to raise the temperature is given as

Q = n c ΔT

Q = (0.0833) (25.35) (18.3)

Q = 38.6 J

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.
