Reflector telescopes ( newtonian, gregorian, a) explain and describe the advantages and disadvantages mirror / reflector telescope types listed below, also compare them in relative to each other. - newtonian telescope- gregorian and cassegrain (classic)(for the most part, there should be looked at amateur telecopes and/or in association with when you make a telescope yourself)b) what are the benefits and disadvantages are by having a hole in the center of the primary mirror on reflector telescopes (gregorian / cassegrain)these questions are linked to a project where a newtonian telescope is being made.

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.
