Un cuerpo de 1250 kg se mueve sobre una superficie horizontal por la acción de un mo tor que produce una fuerza de 24500 N. Sabiendo el cuerpo solo aprovecha el 45% de la fuerza que genera el motor y que el coeficiente de rozamiento es 0,15, la aceleración que experimenta el cuerpo vale: a) 80 m/s

b) 7,9 m/s?

c) 7,3 m/s

If the temperature were raised very high, classically what would we expect the heat capacity per object to be for this one-dimensional system? give a numerical value. chigh t = __ j/k/object (one reason for the discrepancy is that the high-temperature limit assumes that the number of oscillators is large (n > > 1), which is not the case in this tiny system.)

The image below shows numerous volcanic mountains in the pacific northwest. what is the most likely cause of the volcanic and earthquake activity in this region?

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.)
