Answer:
A voltage-controlled resistor (VCR) is a three-terminal active device with one input port and two output ports. The input-port voltage controls the value of the resistor between the output ports. VCRs are most often built with field-effect transistors (FETs). Two types of FETs are often used: the JFET and the MOSFET.

Answer:
Explanation:
As we know that the wavelength of light is given by
now we know that
now from above equation we know
now the diameter of the bead is given as
Now total number of wavelengths that travel in the bead is given as
<u>Answer:</u> The new pressure will be 1.69 atm
<u>Explanation:</u>
Gay-Lussac's law states that the pressure of the gas is directly proportional to the temperature of the gas at constant volume and the number of moles.
Mathematically,
(At constant volume and number of moles)
OR
.....(1)
are the pressure and temperature of the gas
are the final pressure and temperature of the gas
We are given:
Putting values in equation 1, we get:
Hence, the new pressure will be 1.69 atm
