An iron has an aluminium plate with a mass of 1.5 kg. Calculate the thermal energy stored in the plate
when the temperature rises from 20°C to 200°C. The
specific heat capacity of aluminium is 913 J/kg°C.

The slope of a velocity time graph over any interval of time gives the during that interval

What determines the amount of inertia an object has

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
