A4 mm-diameter electrical wire is insulated by a 3 mm-thick rubberized sheath (k = 0.15 w/m·k), and the wire/sheath interface is characterized by a thermal contact resistance of 4 × 10−4 m2 ·k/w. the convection heat transfer coefficient at the outer me 3371, fall 2019, simmons page 1 of 2 surface of the sheath is 20 w/m2 ·k, and the temperature of the ambient air is 22◦c. if the temperature of the insulation may not exceed 60◦c, what is the maximum allowable electrical power that may be dissipated per unit length of the conductor? what is the critical radius of the insulation?

An electromagnet is a material in which the current produces electromagnetism and is passed to the core.  so to fill in the blanks, choices would be better if there were.an electromagnet is a magnet produced by electric current with a metal core

Stars are born within the clouds of dust and scattered throughout most galaxies. a familiar example of such as a dust cloud is the orion nebula. turbulence deep within these clouds gives rise to knots with sufficient mass that the gas and dust can begin to collapse under its own gravitational attraction. as the cloud collapses, the material at the center begins to heat up. known as a protostar, it is this hot core at the heart of the collapsing cloud that will one day become a star. three-dimensional computer models of star formation predict that the spinning clouds of collapsing gas and dust may break up into two or three blobs; this would explain why the majority the stars in the milky way are paired or in groups of multiple stars.therefor, i would say the answer is: dust and gases contract.i hope this ! < 3

Th answer is 3200 m/s
