Athin film of oil of thickness t is floating on water. the oil has index of refraction no = 1.4. there is air above the oil. when viewed from the air in the direction normal to the surface, there is constructive interference of reflected red light with l = 675 nm. find the minimum thickness t of the oil film that will give constructive interference of reflected light with l = 675 nm.
the pancreas is not a part of the respiratory system. the others are.also, brainly does not accept questions from quizes, tests, and exams.
cold temperature can't "flow" into a warmer object, in this case, the person's hand. the heat energy of the hand gets transferred to the colder object, the ice.
b.) false pathology is the study of disease on the body.
recall the equation relating an object's change in thermal energy to its change in temperature:
δq = mcδt
δq is the change in thermal energy.
m is the mass of the object.
c is the object's specific heat.
δt is the object's change in temperature.
m = 0.5 kg = 500g
δt = (7-0)⁰c = 7°c
online sources say the specific heat of silver is 0.240 j/g⁰c
substitute the terms in the equation with the given values and solve for δq:
δq = 500×0.240×7δq = 840 j
