Presume a ship cruises with a constant velocity when the thrust from its engines is a constant 10000N. What is the acceleration of the ship? What is the force of air resistance acting on the ship?

The Fermi energy for silver is 5.48 eV. Which of the following is true : (a) the density of energy states is greater at 2 eV (b) the density of energy states is greater at 6 eV or (c) the density of energy states is same near both energies ?

In an oscilloscope, an electron is accelerated from rest through a voltage of 1.14 x 10 ^3 V it then passes through deflecting plates 2.00 cm apart, across which there is a voltage of 412V. Its velocity when it enters the plate is perpendicular to the electric field of the plates. When the electron leaves the plates, what distance will it have moved toward the positive plate?

James bond (mass 78 kg) is running to catch a bag (mass 23 kg) containing an
antiserum to a deadly disease. Initially Mr. Bond is running 4.4 m/s north and the bag is travelling 2.9 m/s east. What is the final velocity (magnitude and direction) of James and the bag immediately after the catch (collision).
