The next few questions refer to the Golden Great Bridge, built on planet Tehar in a galaxy far, far away. The bridge-building technology on Tehar is not very well developed: The bridge is just a long slab of pure gold with the opposite ends resting on the shores of the river. In the spring, when the air temperature is 100 Celsius, the length of the bridge is 160.0m . Answer the questions below knowing that the value theta of for gold is 1.42 x 10 ^-5 degrees Celsius ^-1. Compared to its length in the spring, by what amount delta L winter does the length of the bridge decrease during the Teharian winter when the temperature hovers around -150 Celsius? and Compared to its length in the spring, by what amount delta L summer does the length of the bridge increase during the Teharian summer when the temperature hovers around 700 Celsius? An equation given is L-L1=theta*L1(T-T1)

Boxing gloves are padded to lessen the force of a blow. (a) calculate the force exerted by a boxing glove on an opponent’s face, if the glove and face compress 7.50 cm during a blow in which the 7.00-kg arm and glove are brought to rest from an initial speed of 10.0 m/s. (b) calculate the force exerted by an identical blow in the gory old days when no gloves were used and the knuckles and face would compress only 2.00 cm. (c) discuss the magnitude of the force with glove on. does it seem high enough to cause damage even though it is lower than the force with no glove?
