El planeta Urano completa un periodo de traslación solar en 83,75 años; su radio es de 25.559 km y su masa se calcula en 8,7. 10^25 kg.
Con estos datos debemos CALCULAR:
a) distancia al sol
b) fuerza de atracción gravitatoria con la que el sol lo mantiene en órbita
c) gravedad en su superficie
d) el peso de una persona que en la tierra pesa 80 kg.
e) la velocidad a la que se debería poner en órbita una sonda a 25.000 km de altura sobre su superficie.

Global warming will produce rising sea levels partly due to melting ice caps but also due to the expansion of water as average ocean temperatures rise. to get some idea of the size of this effect, calculate the change in length (in m) of a column of water 1.45 km high for a temperature increase of 1.12°c. assume the column is not free to expand sideways. as a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
