what is the maximum current imax in a straight superconducting niobium wire of radius 1.5 mm ? keep in mind that the superconductivity of a niobium wire is destroyed if the magnetic field at the surface of the wire reaches or exceeds 0.10 t .

The total amount of energy contained in an object

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
