As per energy conservation we know that

Energy enter into the bulb = Light energy + Thermal energy

so now we have

energy enter into the bulb = 100 J

Light energy = 5 J

now from above equation we have

$100 = 5 + heat$

$Heat = (100 - 5) J$

$Heat = 95 J$

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.

Naddika [18.5K]

Switched Circuit: This type of connection only maintains a dedicated physical circuit or path between two network nodes for the duration of the connection before data may be transmitted.

<h3>What do you mean by circuit?</h3>

A circuit in electronics is a complete circular channel via which electricity flows. A current source, conductors, and a load make up a straightforward circuit. The term circuit can be used in a broad sense to refer to any permanent path that energy, data or a signal can go through.

<h3>What are the 3 types of circuits?</h3>

Circuits can be divided into three categories: series, parallel, and series-parallel. The typical configuration of a single electrical circuit includes one or more resistance or load devices.

<h3>What function does a circuit represent?</h3>

The closed loop in which electricity can move is referred to as a circuit. Electricity can flow in a closed circuit without interruption from the power source through the conductor or wire to the load before returning to the ground or power source.

Carmen is heating some water and trying to measure the temperature of water using a Celsius thermometer. Which measurement can s

andrew-mc [135]

<u>100° C</u> she can expect once the water begins to boil.

<u>Option: B</u>

<u>Explanation:</u>

The boiling point for water at 1 pressure atmosphere of sea level is 212 ° F or 100 ° C. That value isn't a fixed. Water's boiling point is dependent on the ambient pressure, which varies based on elevation. At a lower temperature, water boils as one gains altitude like getting higher on a hill, and boils at a higher temperature if one increases the atmospheric pressure of returning to or below sea level.

It also relies upon the water's purity. Water containing contaminants like salted water boils at a level higher than pure water. This effect is called acceleration of the boiling point and is one of the material's colligative features.

Air having a pressure of 40 psig and a volume of 8 cu ft expands isothermally to a pressure of 10 psig. Find the external work p

DerKrebs [107]

Answer:

357.6 lb-ft

Explanation:

V = Volume = 8 ft³

dP = Change in pressure = (40-10) = 30 psig

Work done is given by

$W=VdP\\\Rightarrow W=8\times (40-10)\\\Rightarrow W=240\ psig.ft^3$

$30\ psig=44.7\ psi\\\Rightarrow 1\ psi=\dfrac{30}{44.7}$

So, converting to ft-lb

$\dfrac{240}{\dfrac{30}{44.7}}=357.6\ lb-ft$

The external work performed during the expansion is 357.6 lb-ft
