Three 100 N resistors are connected as shown in the figure. The maximum power that can safely be deliv resistor is 26.5 w. 100 N 100 N b 100 N (a) What is the maximum potential difference that can be applied to the terminals a and b? 77.217 (b) For the voltage determined in part (a), what is the power delivered to each resistor? resistor on the left 26.5 w 6.25 How is the current through this resistor related to that of the leftmost resist that imply about the ratio of the powers delivered to the two resistors? W 6.25 resistor at the top of the loop resistor at the bottom of the loop You are correct that the power delivered to this resistor is the same as the p the top resistor. W (c) What is the total power delivered to the combination of resistors? 38.75 The total power delivered to a combination of resistors will be the same if the set of resistors is re resistor with a resistance equal to the equivalent resistance.

Please use neat handwriting and show work A light ray traveling in air hits the surface of an unknown liquid ina beaker as shown in the picture. When the angle 0 is 55° the ray hits at a point where x = 2 cm. Calculate the index of refraction of the liquid.

13. A railroad car of mass 2.50 X 104 kg is moving with a speed of 4.00 m/s. It collides and couples with three other coupled railroad cars, each of the same mass as the single car and mov- ing in the same direction with an initial speed of 2.00 m/s. (a) What is the speed of the four cars after the collision? (b) What is the decrease in mechanical energy in the collision?
