A paper filled capacitor is charged to a potential difference of 2.1 V and then disconnected from the charging circuit. The diel
Goryan [66]

Answer:

Part a)

V' = 7.77 Volts

Part b)

k' = 6.27

Explanation:

As we know that capacitor plate is connected across 2.1 V and after charging it is disconnected from the battery

So here we can say that charge on the plates will remain conserved

So we will have

Q = kC(2.1)

now dielectric is removed between the plates of capacitor

so new potential difference between the plates

V' = \frac{Q}{C'}

V' = \frac{kC(2.1)}{C}

V' = 3.7 \times 2.1

V' = 7.77 Volts

Part b)

Now the capacitor plates are again isolated and unknown dielectric is inserted between the plates

So again charge is same so potential difference is given as

V" = \frac{Q}{k'C}

0.59 V = \frac{kCV}{k'C}

0.59 = \frac{3.7}{k'}

k' = 6.27

What is threshold frequency
spayn [35]
Threshhold frequency is defined as the minimum light frequency necessary to start photo-electric emission from the surface. This frequency is just effecient enough to emit electrons without any additional force or energy. this minimum frequency creates the necessary result that is sought by the person. The photo electric emission for certain metals can occir with threshhold frequency. The importance of this threshhold frequency lies in the fact that this has been used to create numerous instruments like amplifiers for use of people.

how much voltage is in the primary coil if there are 3200 winding in the secondary coil 500 winding in the primary and 25v in th
Tema [17]

Answer:

Voltage in the primary winding of the coil is 3.9 V

Explanation:

As we know by the principle of transformer we have

\frac{V_s}{V_p} = \frac{N_s}{N_p}

here we know that

V_s = 25 volts

N_s = 3200

N_p = 500

now we have

\frac{25}{V_p} = \frac{3200}{500}

V_p = 3.9 Volts

What kind of energy does a rubber band have when it is stretched?
RideAnS [48]
Elastic potential energy. When you stretch a rubber band it has the "potential" to do work, to fly in a given direction. In doing so it changes it's elastic potential energy to kinetic energy.

What is nuclear fission? why is this process important to stars?
KIM [24]

Nuclear fusion is a reaction in which two or more atomic nuclei come very close and then collide at a very high speed and join to form a new nucleus. This process is important to stars because they get their energy from the nuclear fusion process
