The receiving antenna becomes misaligned by 30° to its original position. The power of the received signal in this new position is 12 uW.
Calculate the power that was received in the original position.
Calculate the minimum time between the wave leaving the transmitting antenna
and its reception.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2·k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg·k, and 20 w/m·k.

Five structural isomers have the formula c6h14. where needed, draw the structure and give the iupac name of all five isomers.
