Marcela tiene una temperatura corporal de 37°C y toca con sus manos una olla metálica que contiene agua a punto de ebullición. Luego mete la mano en hielo.

* Para Marcela, ¿Cuál objeto está caliente y cuál está frio?

* ¿Cuál sería la respuesta de la pregunta anterior si la temperatura normal de
marcela fuera hipotéticamente de 150°C?

Which feature of a heating curve indicates a change ofn state

Astone is thrown into a pond. what happens to the amplitude of the resulting waves as they get farther from the point where the stone hit the water? explain.

Alinearly polarized electromagnetic wave has an average intensity of 196 w/m^2. this wave is directed towards two ideal polarizers (in real polarizers, transmission is also effected by reflection and absorption). polarizer a is oriented with its transmission axis at an angle of θ_1=20.8∘ with the incident electric field. polarizer b has its axis at an angle of θ_2=63.0∘ with the incident electric field. what is the average intensity of the wave after it passes through polarizer a? what is the average intensity of the wave after it passes through polarizer b? suppose that the two polarizers a and b are interchanged. what would the average intensity be after passing through both polarizers?
