Refraction of Light

Light travels a distance of .960 m in 4.00 ns in a given substance. What is the index of refraction of this substance? A ray of light enters the long side of a 45-90-45 prism and undergoes two total internal reflections. The result is a reversal in the ray's direction of propagation. Find the minimum value of the prism ...continues

Acceleration and Decceleration problem

On December 10, 1954, Dr. John Paul Stapp rode a rocket sled to a speed of 282m/s that is (632 mi/h), enduring extreme accelerations. He was accelerated from rest to his top speed in 5.00s and brought jarringly back to rest in only 1.40s! Calculate his acceleration and decceleration. Express each in multiples of g by taking its ...continues

Dependence of rate of cooling of a body on the surrounding temperature

A hot body cools from 90 degree celcius to 80 degree celcius in 5 minutes when placed in a room of temperature 30 deg C. How long will it take to cool from 70 deg C to 60 deg C in the same room ?

Vectors and the Graphical Method

Vector A is 3.00 units in length and points along the positive x-axis. Vector B is 4.00 units in length and points along the negative y-axis. Use the graphical methods to find the magnitude and direction of the following vector: B.) B-A The work I need to show to complete this problem is a free body diagram, formulas, wor ...continues
