Please help with these questions; no need to explain either. Thank you!! Which is/are true about the peripheral somatosensory system? a. receptive fields are usually large where fine analysis is required (like finger tips). b. receptor cells are best at distinguishing two or more simultaneous stimuli when the stimuli are within the cell’s receptive field. c. receptive fields are arranged...
I need both.
5. A Hall effect sensor 10mm long, 10 microns wide and one micron thick is made of silicon with an electron concentration of 5 * 1012 per cubic centimeter. What is the Hall voltage when exposed to a 0.17 magnetic field and fed a current of 10 microamps. 6. Two thin, straight parallel wires suspended 10 mm...
#12: An electron with v = (3.52x106 î - 8.99x106 k) m/s enters a magnetic field of B =5.41 k T. It moves in a helical path as shown. What is the radius of the cylinder around which the helix winds and what is the speed of the particle after 0.50s? *hint: you can ignore one of the components of...
One hundred turns of insulated copper wire are wound into a solenoid of cross sectional area 0.100 m2. Connecting the coil to a 10 resistor completes the circuit. The magnetic field along the coil axis is made to change from 1.00 T in one direction to 1.00 T in the other direction. The total charge which flows through the...

An object is placed as shown in the figure above. The center of curvature and the focal point F of the reflecting surface...
A particle of charge q and mass m is bound in the ground state of a one-dimensional harmonic oscillator potential with frequency oo. At time t-0 a weak spatially uniform electric field (E) is turned on, so that the perturbation to the Hamiltonian can be described as R'(t) =-q Exe-t/t for t> 0. Using first order, time-dependent perturbation theory, calculate...
