1. Determinar el valor del volumen de su heladera (hay que calcular el valor del volumen). Debe enviar fotos del procedimiento que realiza para responder este punto
(qué medidas tomó, con qué instrumento hizo la medida)
2. ¿Cuáles son las unidades de Presión? Averigüe:
a. porqué no es conveniente no usar zapatos con tacos para caminar en la arena
(desde un punto de vista físico)
b. para generar menor presión sobre el suelo, es conveniente estar parado sobre los
dos pies o sobre uno. Justifique
3. Averigüe cuál es el valor en las tres escalas:
a. temperatura corporal “normal”
b. temperatura del núcleo terrestre
c. temperatura del sol (promedio)
4. Graficar un termómetro en escala Celsius, donde ubique el punto de fusión de:
aluminio, plata, potasio, plomo, mercurio, cobre y alcohol. Es como si ubicara los
valores en la recta numérica.

Which diagram correctly demonstrates the various forces acting on a ball moving horizontally with some speed?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.

To understand the behavior of the electric field at the surface of a conductor, and its relationship to surface charge on the conductor. a conductor is placed in an external electrostatic field. the external field is uniform before the conductor is placed within it. the conductor is completely isolated from any source of current or charge. part a: which of the following describes the electric field inside this conductor? it is in the same direction as the original external field.it is in the opposite direction from that of the original external field.it has a direction determined entirely by the charge on its surface.it is always zero. part b: the charge density inside the conductor is: 0non-zero; but uniformnon-zero; non-uniforminfinite part c: assume that at some point just outside the surface of the conductor, the electric field has magnitude e and is directed toward the surface of the conductor. what is the charge density η on the surface of the conductor at that point? express your answer in terms of e and ϵ0
