Suppose you charges parallel plate capacitor with a dielectric between the plates using a battery and the. Remove the bater, iso
Makovka662 [10]

Answer:

A) increase.

Explanation:

  • By definition, the capacitance of a capacitor, is the charge on one of the plates, divided by the potential difference between them, as follows:

        C = \frac{Q}{V} (1)

  • At the same time, we can show (applying Gauss' Law to the surface of one of the plates), that the capacitance of a parallel-plate capacitor (with a dielectric of air), can be written as follows:

       C = ε₀*A / d  (2)

  • If the space between plates, is filled with a dielectric of dielectric constant κ, the above equation becomes:

       C =\frac{\epsilon_{0}*\kappa*A}{d} (3)

  • If the capacitor, once charged, is disconnected from the battery, charge must keep the same.
  • Now, if we remove the dielectric, as stated in (3) and (2), the capacitance C will decrease when removing the dielectric.
  • From (1) if C decreases, and Q remains constant, in order to keep both sides of the equation equal each other, V (the potential difference between plates), must increase.

A force of only 150 N can lift a 600 N sack of flour to a height of 0.50 m when using a lever as shown in the diagram below. a.
Snowcat [4.5K]
Actually the question is not clear. The Benefit of lifting using lever is that you can apply force in a convenient direction and you can use very less force to lift object by balancing the torque due to object.For example you want to lift a mass of 4N with a force 2N you can use a class 2 lever and maintain the ratio between the distances of the body and the point of application of force from the fulcrum to be 1:2.In any case balance the torque to get the required force.

Is NaCH an element? Why or why not?
amm1812
<span>NaCH is not an element, it is a compound. An element can be found and identified on the periodic table to elements. A compound is a combination of two of more elements. NaCH is composed of three elements: Na (sodium), C (carbon) and H (hydrogen), making it a compound.</span>

Which of the following are ohmic materials? a. Batteries Wires Resistors Light bulb filaments b. Batteries, wires, resistors, an
Bingel [31]

Answer:

A., B., and C.

Explanation:

An Ohmic material is a material that obeys Ohm's Law, V = IR.

In contrast, a non-Ohmic material is one that does not obey Ohm's law.

Ohm's law states that the voltage across an electrical object is proportional to the current flowing through it, with the constant of proportionality being Resistance, R (in Ohm's).

The only Non-Ohmic material is the semiconductor, as semiconductors do not obey Ohm's law.
