The current I in an electrical conductor varies inversely as the resistance R of the conductor. The current is 3 amperes when the resistance is 810 ohms. What is the current when the resistance is 413 ohms? Round to the

nearest tenth of an ampere if necessary. A)1.5 amperes B)0.65 amperes C)5.9 amperes D)0.17 amperes

Aparticle moves according to a law of motion s = f(t), 0 ≤ t ≤ 12, where t is measured in seconds and s in feet. f(t) = cos(πt/6) (a) find the velocity at time t (in ft/s).

Ateam of astronauts is on a mission to land on and explore a large asteroid. in addition to collecting samples and performing experiments, one of their tasks is to demonstrate the concept of the escape speed by throwing rocks straight up at various initial speeds. with what minimum initial speed vesc will the rocks need to be thrown in order for them never to "fall" back to the asteroid? assume that the asteroid is approximately spherical, with an average density p 3.84 x108 g/m3 and volume v 2.17 x 1012 m3 recall that the universal gravitational constant is g 6.67 x 10-11 n m2/kg2

What tightening torque should be used for a hexagonal head screw (not split-bolt) on a 250 kcmil conductor?
