A variable, Q, is reported to have a value of 2.360 x 10-4 kg ? m2/h.
(a) Write a dimensional equation for Q’, the equivalent variable value expressed in American engineering units, using seconds as the unit for time.
(b) Estimate Q’ without using a calculator, following the procedure outlined in Section 2.5b. (Show your calculations). Then determine Q’ with a calculator, expressing your answer in both scientific and decimal notation and making sure it has the correct number of significant figures.
The prism shown here is used to totally reflect light at a 90 angle. No surface of this prism is silvered. Use Snell’s law to explain why total reflection occurs. What is the minimum refractive index of the prism for total reflection?
