A d = 3.63 mm diameter wire carries an electric current of I = 22.4 A when the electric field is E = 5.74 \times 10^{-2} V/m along the wire. a. What is the current density? b. What is the conductivity o...
If you still don't quite understand what is meant by density, recognize that a gallon of milk (which is a particular volume of milk) weighs the same every time you buy one. A half gallon of milk weighs half as much. If you multiply the volume times the density you get the weight. ...

What happens when air currents rise inside a cloud? What happens when a wetland dries up? What happens if the water cycle is interrupted? What happens in the water cycle? What happens to air as it rises? What happens to rainwater that falls on land?
In this context, density refers to the number of ports an Ethernet switch allows. The more ports on a switch, the more devices that can connect to the network directly. Having multiple ports allows for simultaneous connections, which is vital for office environments. For example, a business ma...
What is the job of the insulator in a circuit? a. To keep electric charges inside the pathway. b. To provide electricity. c. To transform electrical energy. d. To provide an unbroken path for electrons. What is the role of loose electrons in heat conductors?
These disruptive currents — often called "noise" or "electromagnetic noise" — can come from an external source or get created by other components inside the device. When EMI occurs, it disrupts the functioning of the device and can cause unintended operations to occur. Depending on the ...
Organisms living inside the sapwood and heartwood have a higher likelihood of surviving harvest, and harvesting processes that minimize bark disturbances will increase the survivorship of organisms that have colonized the outer surfaces of round wood. Round wood is often piled and stored at the ...
is capable of closing the reed switch contacts. Reed switches can be used with permanent magnets (for example, to detect doors closing), but for the reed relays, the field is generated by a coil, which can have a current passed through in response to a control signal. The coil surrounds...
