Una jeringa hipodérmica tiene un émbolo con una área transversal de 2.5 cm2

y una aguja de 5.0 x 103
cm2
. a) Si se
aplica una fuerza de 1.0 N al émbolo, ¿qué presión manométrica habrá en la cámara de la jeringa? b) Si hay una pequeña
obstrucción en la punta de la aguja, ¿qué fuerza ejercerá el fluido sobre ella? c) Si la presión sanguínea en una vena es
de 50 mm Hg, ¿qué fuerza deberá aplicarse al émbolo para inyectar fluido en la vena?

answer:   you might love summer weather, but you don’t want it to feel like the sun is inside your car. but a hot car that just won’t seem to cool down might be a bigger of a problem than you think. your car relies on being at the right temperature.

explanation:

d is the correct answer

jupiter is the largest planet in our solar system, having a mass and radius that are respectively, 318 and 11.2 times that of earth. suppose that an object falls from rest near the surface of each planet and that the acceleration due to gravity remains constant during the fall. each object falls the same distance before striking the ground. determine the ratio of the time of fall on jupiter to that on earth.
