A meterstick (L = 1 m) has a mass of m = 0.196 kg. Initially ithangs from two short strings: one at the 25 cm mark and one at the75 cm mark.1) What is the tension in the left string? 2) Now the right string is cut! What is the initial angularacceleration of the meterstick about its pivot point? (You mayassume the rod pivots about the left string, and the string remainsvertical)3) What is the tension in the left string right after theright string is cut? 4) After the right string is cut, the mete

SOLVED:A meterstick moving at 0.900 c relative to the Earth's surface approaches an observer at rest with respect to the Earth's surface. (a) What is the meterstick's length as measured by the observer? (b) Qualitatively, how would the answer to part (a) change if the observer started running toward the meterstick?
