Answer:
3.8*10^2J/(g°C),
Step-by-step explanation:
Heat Energy = mcΔt
23.6 = 5c(35-22.6)
23.6 = 5c(12.4)
23.6 = 62c
c = 23.6/62
c = 0.3806
c = 3.8*10^2J/(g°C),gold
Hence the specific heat of the metal is 3.8*10^2J/(g°C),

Step-by-step explanation:
Sin2α = 2SinαCosα.
Cos2α = (Cosα)^2 - (Sinα)^2.
Sin4α can be written as Sin2(2α).
Similarly Cos4α can be written as Cos2(2α).
It is given that tanα=3.
Sinα(Sinα) = [], the values either be both positive or both negative, as the value of tanα is positive only on first and third quadrant.
Sin4α = .
Cos4α =
