We have a heavy power cable which is 1 foot in diameter with resistance 0.05 u 12 per foot. connect the cable to a voltage source of 115 v. how long is the cable over which the power loss through the resistance of the cable will reach 10^10 watts?

Ahorizontal wire is tied to supports at each end and vibrates in its second-overtone standing wave. the tension in the wire is 5.00 n, and the node-to-node distance in the standing wave is 6.28 cm. (a) what is the length of the wire? (b) a point at an anti- node of the standing wave on the wire travels from its maximum upward displacement to its maximum downward displacement in 8.40 ms. what is the wire's mass?

Engineers find a new metal that is stronger than steel but much lighter. this material is also significantly cheaper than what is currently used for most aircraft, available in large quantities, and easy to manufacture. the engineers are excited because this new material will lower the costs of buying and operating airplanes for companies. what is probably the best step for the engineers to make next?

If the textbook weighs 19.6 newtons on venus, what is the strength of gravity on venus?
