One hundred turns of insulated copper wire are wrapped around a wooden cylindrical core of cross-sectional area 1.30×10-3 m2. The two terminals are connected to a resistor. The total resistance in the circuit is 15.0 O. If an externally applied uniform longitudinal magnetic field in the core changes from 1.60 T in one direction to 1.60 T in the opposite direction, how much charge flows through the circuit (in Coulombs)?
If you were to use a column twice the length of the one that you will actually use in lab, how do you think the retention times of the compounds would be affected? How do you think the seperation of the peaks would be affected? Please answer & explain.
A technician wraps wire around a tube of length 40 cm that has a diameter of 6 cm. When the windings are evenly spread over the full length of the tube, the result is a solenoid containing 600 turns of wire. A) determine the self inductance of this solenoid B) if the current in this solenoid were to increase at a rate of 5A/s, what would be the induced potential in the solenoid?
How were core promoter elements identified? How would you do this in a new organism?
a) what is the resistance of the wire in the solenoid?
b) how much voltage would need to be applied to the solenoid to
create a 5.00 mT magnetic field?
Consider a solenoid made of copper wire. The solenoid is 5.00 cm in diameter and 30.0 cm in length. The copper wire has a diameter of 0.50 mm and is wound with 20 turns per cm. The resistivity of Cu is 1.72 Times 10-8 Ohm *m.
in part of the experiment, you measure each metal
combination twice, but the red and black leads of the meter were
switched for each test. compare the voltages of each metal
combination. what pattern do you see in the voltages depending on
which way the red-black leads or the multimeter are connected to
the metals? why do you think you saw a pattern in these
voltages?

22 Intel Dual Core processors were shock tested to see what level of static shock would destroy the CPU chips. The average voltage for this sample was 47 volts with a standard deviation of 1.5 volts. Please give the LOWER VALUE for a 95% confidence interval for the true voltage level and submit the answer with 2 decimal places.
A coil composed of five circular loops of wire (area of each loop is 0.125 m^2) lies in the plane of this sheet of paper. A magnetic field pointed perpendicular out of the sheet of paper (towards us), and begins at a strength of 2.5 tesla. Over 0.025 seconds, the magnetic field reduces to zero tesla. (a) Calculate the induced voltage in this coil caused by this changing magnetic field. (b) What direction will current flow around this coil (clockwise...
The armature of a simple ac generator has 20 circular loops of wire, each with a radius of 10 cm. It is rotated with a frequency of 60 Hz in a uniform magnetic field of 650 mT a)What is the maximum emf induced in the loops? b)How often is this value attained? c)If the time period in part B were cut in half, what would be the new maximum emf value?
I'm a bit confused on how to
go about this question. Any help would be great, thank you!
The resistivity of gold is 2.44x10-8 •m at room temperature. A gold wire that is 0.7 mm in diameter and 41 cm long carries a current of 140 mA. What is the electric field in the wire? 2.2x10-2 V/m 1.1x10-2 V/m 7.0x10-3 V/m 2.2x10-3 V/m 8.9x10-3 V/m
