Asoap bubble, when illuminated with light of frequency 5.27 hz × 1014 hz, appears to be especially reflective. if it is surrounded by air and if its index of refraction is 1.33, what is the thinnest thickness the soap film can be? (c = 3.00 × 108 m/s)

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.

This is one type of line graph in which the independent variable is time plotted on the x axis and the dependent variable, also numerical, is plotted on the y axis.
