A Summary of The Corner Shop

Please find below the summary of The corner Shop. Do let me know for change, improvement anything you think. It is often said ‘The best ghost stories don’t have ghosts in them; rather, you see the result of its actions.’ For centuries readers have been attracted to the mysterious air surrounding ghosts and other supernatural beings. It is probably this sense of wonder and fear that makes ghost stories so addictive and hard to put down. An example of such a story is Cynthia Asquith’s The Corner Shop. The Corner Shop starts out as a happy story of a man, Peter Wood who discovers an antique shop filled with vintage trinkets run by two charming, young women. Upon browsing through its offerings, the man purchases a jade frog figurine at a throwaway price. Content with his purchase, Peter decides to make frequent visits to this lovely little shop. However, there is something sinister lurking behind the scenes. On the second visit to the store, Peter is in for an eerie surprise. Gone…

3 Commercial Unit Of Electrical Energy Physics Class 10

Th S.I. unit of energy is joul(J).
Let the power (p) of an electrical appliance = P watt
Let it is used for t seconds.
Then Electrical energy consumed (W) = P x t watt-second
i.e. W = Pt Watt-second
or W = Pt Joul (Joul is Mechanical unit equivalent of Watt-second)
In practice bigger unit like Watt-Hour (Wh) or Kilo Watt Hour (KWh) is used for Electrical energy consumption. Watt-Hour : It is the electrical unit consumed by an electrical appliance of P watt that was used for 1 hour. 1 w-hr = 1 watt x 1 hr
= 1 w x (60x60)second
=3600 watt-second
=3600 Joul
1 Whr =3600 J
Kilowatt-Hour: One kilowatt-hour is the electrical energy consumed by an electrical appliance of power rating 1 kw when it used for 1 hour.
1 KWhr = 1 kilowatt x 1 hr
= 1000 w x (60x60)second
=3.6x106 watt-second
=3.6x106 Joul
1 KWhr = 3.6x106 J
The electrical energy consumed in our houses or in industries are measured in KWhr . This is also called ! unit electrical unit consumed. The rate delared by gover…

2.Electrical Power and its Expression For Class 10

Electrical Power: Rate of electrical energy supplied by a source e.g. a power station or an alternator or a dc battery etc is called electrical power.
∴ Power = Electrical Energy supplied / Time
if Power = P
Energy supplied = W
and Time = T
Then P = W / T
if W is in Joul
T in second
then unit of power will be Joul/Second (J/S); which is called watt.
∴ watt = j/s
∴Electrical Power, P=W/t=V.I=V2/R=I2.R

Love Concern Humanity And Trust are the Eccentric Features of Mankind

Love Concern Humanity And Trust are the Eccentric Features of Mankind . Quoting examples from chapters : "The Last Leaf", Journey by Night", and "God Lives in Panch", Justify the statement . The main element which makes us differ from the rest are the qualities we possess.” Human nature is something which cannot be taught but which is self-existent. We, having an upper hand in the eco system, have something which other creatures lack. It is that object of our conscience which makes us good. Saying simply good is not enough because we are much more than being good. It is this positive quality in us, which makes us good. “The last leaf” by O Henry tells us the tale about unconditional concern which is not bounded by relationship but out of sheer care for one another. It is not only those people who are bounded by relationship care for one another but also those people who understand are not bounded but yet understand the pain of another. This chapter has taugh…

Ohm's Law of Current Electricity Physics Class 10

Ohm's Law: It can be defined as "The potential difference (P.D.) across a conductor is proportional to the current flowing through it provided that physical conditions remain constant." If V = Potential Difference (P.D.)
I= current
Then we can write V ∝ I
Or V= I. R
R= Constant and it is known as resistance of the conductor.
It also means that
V/I = Constant(R) , If all surrounding conditions are constant.
The resistance of a conductor depends on:
1. Length of the conductor.

2. Area of cross section of the conductor.

3. Type of material of the conductor.
It is because of the type of the material different conductors have different conductance. Copper is more good conductor than iron. Similarly silver is more good conductor than copper. Conductance of silver is slightly more than copper. As silver is costlier than the copper therefore we use copper instead of silver to ignore slight advantage of conductance. 4. Temperature of the conductor.
If the temperat…
