Por una manguera horizontal de 4.50 cm de diámetro fluye agua con una rapidez de 0.510 metros por segundo y sale por una boquilla de 0.650 cm de diámetro. ¿Cuál debe de ser la presión absoluta del agua de la manguera, si la presión en la boquilla de salida es igual a la presión atmosférica?

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.

a.metals can become magnetic if they have many spinning electrons that create magnetic fields.d.only some metals are attracted by magnets; these metals are called ferromagnetic.

d.wrapping an insulated wire around a metal with ferromagnetic properties and applying an electric current.

molecules are free to separate from each other and will take on the shape of the container. molecules move completely at random and high speeds. they vibrate in a fixed position and do not move around much. molecules expand to the edge of their container.
