The biochemistry that takes place inside cells depends on various elements, such as sodium, calcium and potassium that are dissolved in water as ions. These ions enter cells during narrow pores in the cell membrane known as ion channels. Each ion channel, which is formed from a specialized protein molecule, is selective for one kind of ion. Measurements with microelectrodes have shown that a 0.30-nm-diameter potassium ion (K+) channel carries a current of 1.8 pA.
What is the current density in the ion channel?
A square current loop 4.50cm on each side carries a 540mA current. What is the magnitude of the torque on the current loop
Find the resultant forces and moments at wrist, biceps muscle force, elbow and shoulder and joint reaction force using 2-D static analysis.
A closed surface encloses a net charge of -3.50. What is the net electric flux through the surface? Use 8.85×10?12 for the permittivity of free space.

Towns A and B in are 80.0 km apart. A couple arranges to drive from town A and meet a couple driving from town B at the lake, L. The two couples leave simultaneously and drive for 2.50 . Car 1 has a speed of 90.0 km/h. If the cars arrive simultaneous..
Two resistors A and B are 60,000 and 40,000 (omega sign) respectively and are in series across a constant power supply of 100V. What amount of current is flowing in each of the 3 resistors
A high-speed flywheel in a motor is spinning at 450 rpm when a power failure suddenly occurs. The flywheel has mass 37.0kg and diameter 71 cm. The power is off for 27.0s and during this time the flywheel slows due to friction in its axle bearings...
