An electric eel develops a potential difference of 470 V , driving a current of 0.85 A for a 1.0 ms pulse. A. Find the power of this pulse.
B. Find the total energy of this pulse.
C. Find the total charge that flows during the pulse.

This is the substance(s) formed in a chemical reaction.

Two forces produce equal torques on a door about the door hinge. the first force is applied at the midpoint of the door; the second force is applied at the doorknob. both forces are applied perpendicular to the door. which force has a greater magnitude?

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
