Abattery rated at 7.2 v and 1 j is connected across a light bulb. assume that the internal resistance of the battery is negligible, and that the resistance of the bulb's filament is 100 ω. draw the associated circuit, and label all branch variables, following the associated variable convention. what is the power into the bulb? what is the power into de battery? how long will the battery last in the circuit?

Afoot bridge is made as a simple deck, 4 m long, with a cross section 2 m (wide) and 20 cm thick, and made of wood. the deck is supported at the two ends. the maximum load allowable on the bridge is 10 tons, provided it is uniformly distributed on the deck. to sense this load, a strain gauge is placed at the center of the bridge and its resistance is monitored. if the sensor has a nominal resistance of 350 s2 and a gauge factor of 3.6, what is the reading of the strain gauge at maximum load? the modulus of elasticity for the wood used in the construction is 10 gpa.
