A physics professor sitting on a stationary reference frame gives an exam to the students who are on a spaceship traveling at a speed vrelative to stationary frame. The moment the ship passes the professor, she signals the start of the exam. If she wishes her students to have time T0(spaceship time) to complete the exam, how much time should the professor wait (in the stationary frame) before sending a light signal telling them to stop? Draw a spacetime diagram and express the answer time in terms of T0and vand c.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (ρ = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
