Asap plxxxxxxx A) The earth's radius is 6.37x106m; it rotates once every 24 hours.What is the speed of a point on the earth's surface located at 1/4 of the length of the arc between the equator and thepole, measured from equator? (Hint: what is the radius of the circle in which the point moves?) Express your answer withthe appropriate units.B) The cable lifting an elevator is wrapped around a 1.1-mm-diameter cylinder that is turned by the elevator's motor. Theelevator is moving upward at a speed of 2.9 m/sm/s. It then slows to a stop, while the cylinder turns one completerevolution.How long does it take for the elevator to stop?

Solution: A. First of all, calculate the radius of the particle at one-fourth of the arc measured…

The sample is placed in a uniform magnetic field, and a low frequency ac current is passed through the tissues of the body, perpendicular to the magnetic field. The current will experience a force due to the field. Since the current is switching direction, the magnetic force switches direction too. Different tissues have different conductivities, and this results in different forces at the boundaries between different types of tissue. This creates ultrasonic waves that can be detected with millimeter resolution. Consider a 0.10-mA current of sodium ions moving as an electrolyte through the extracellular fluid within the tissue. If the current is oriented…

Describe the magnetic field that exists between the plates of a charging or discharging capacitor with parallel circular plates. The magnetic field lines are straight lines perpendicular to the plates (ignoring fringing at the edges.) The magnetic field lines are straight lines parallel to the plates (ignoring fringing at the edges.) There is no magnetic field between the plates. The magnetic field lines are circles around an axis perpendicular to the plates (ignoring fringing at the edges.)
