1.When Ox Tucker and his grandfather Smackie went fishing, Ox accidentally caught his hook on Smackieʼs Darth Vader helmet (mass = 1.20 kg) The helmet wouldnʼt break free so Ox spun it around in circles to try to break it loose. As it circled, the helmet made one revolution every 4.00 seconds and was at a distance of 7.00 meters from him.

An object is 10 cm from the mirror, its height is 1 cm and the focal length is 5 cm. what is the image height? (indicate the object orientation by including the + or - sign with the answer.) hi = cm +1 -1 +10 -10

Use the information presented in the graph to answer the questions. which segments show acceleration? which segment indicates that the object is slowing down? what is the velocity of segment b? what is the acceleration of segment b?

You have a resistor and a capacitor of unknown values. first, you charge the capacitor and discharge it through the resistor. by monitoring the capacitor voltage on an oscilloscope, you see that the voltage decays to half its initial value in 2.70 miss . you then use the resistor and capacitor to make a low-pass filter. what is the crossover frequency fc?
