si se dispone de una balanza y de un dinamometro muy sensibles y que con aquella se mide la masa de un objeto de 25 kg en la tierra. Que señalarán la balanza y el dinamómetro si la medida se efectúa a 2000 m de altitud sobre la superficie de la tierra?

An electric clothes dryer has a resistance of 8 ohms. it draws 30 a of current. what is the voltage, in volts, of the wall outlet that it is plugged into?

When a vertical beam of light passes through a transparent medium, the rate at which its intensity i decreases is proportional to i(t), where t represents the thickness of the medium (in feet). in clear seawater, the intensity 3 feet below the surface is 25% of the initial intensity i0 of the incident beam. what is the intensity of the beam "10" feet below the surface? (give your answer in terms of i0. round any constants or coefficients to five decimal places.)

Convection occurs when thermal energy is transferred by the movement of
