A wire 50cm long and having a diameter of 0.05cm is in a room at 20ºC. The specific resistance of the material of wire is 2µΩ per cm cube while its temperature co-efficient is 0.004 at 20ºC. Calculate the resistance of wire at 20ºC, if the temperature of the room rises to 25ºC. Find the new resistance of wire.

Wo small variable-thrust jets are actuated to keep the spacecraft angular velocity about the z-axis constant at ? 0 = 1.16 rad/s as the two telescoping booms are extended from r1 = 1.18 m to r2 = 4.69 m at a constant rate over a period of 124 seconds. the small 19-kg experiment modules at the ends of the booms may be treated as particles, and the mass of the rigid booms is negligible. determine the necessary thrust t for each jet as a function of time where t = 0 is the time when the telescoping action is begun. after you have the general expression for t, answer the questions. show work.

Diego kicks a soccer ball from the end line. his fellow students time and mark the soccer ball as it moves down the field. the graph represents the ball's progress. based on the graph, during what time is the velocity constant and positive?
