Why do you not agree with Lencho calling the post office employees a bunch of crooks?

Posted by Seema Chandel 5 years, 6 months ago

CBSE > Class 10 > English Language and Literature

1 answers

Gaurav Seth 5 years, 6 months ago

Lencho called the post office employees " a bunch of crooks" as he thought that upon asking for help, God sent him 100 pesos but he received only 70 which meant that the rest 30 pesos were stolen by those employees. The fact he didn't know was that those employees were the ones to collect and send him those 70 pesos as a gift from God so that he doesn't loose his faith in the almighty.
Thus, Lencho was wrong in calling them a bunch of crooks.

What is jouls law

i^2 rt

0Thank You

Gaurav Seth 5 years, 6 months ago

Joule’s law of heating states that when a current ‘i ' passes through a conductor of resistance ‘r’ for time ‘t’ then the heat developed in the conductor is equal to the product of the square of the current, the resistance and time.

H = i 2 rt

The reason behind the heat produced is the collision of the free electrons with the lattice ions or atoms while accelerating in presence of the external electric field.

we know that

volt= work done/ total charge or v = w/q

from this we get w= vq

we know that current i = q / t

so q = it

putting this in prev equation

we get w = vit

from ohms law v = ir

putting it in prev eq we get

w = irit = i2rt joule as work is stored as heat soH = I2RT Joules

When 50% of the Indian workforce is doing agriculture, why is the contribution of agriculture to the GDP only 16%? Learn how to jump start your online business for free! As a middle class person what all items do you spend on? You might be spending on housing, food, entertainment, education, clothes, transportation, art, electricity, water, communication… In short, food is just one among the dozen big things you need and spend on. The spending on raw food grains and vegetables/fruits, is only a small part of the monthly budget. Unless you want to be eating and sleeping all day, you have plenty to do with your life. Extrapolate it to the nation. GDP accounts for sum total of all our activities from banking to transportation, from airlines to police, from factories to roads. Food production/consumption is only a small part of it. That is true for any major economy and something quite natural. In the US, the farms alone contribute only a little more than 1% of GDP, for instance. Whether we put 50% of our labour or 10% of our labour on food production, we would not be able to change how much our households spend on food or that we need plenty of things besides food. However, when 50% of people share only 16% of income, there is poverty in farming by default. We are condemning them to low incomes. is why we have to get a majority of our government makes money: 35% is corporation taxes [from their profits], 18% is excise duties [that these corporations buy], 18% is income tax [mostly from employees in these corporations], 17% is customs tax [from what the corporations import] and about 12% is service tax [from what they sell].

An acid is a substance that donates hydrogen ions. ... Now there are more hydrogen ions than hydroxide ions in the solution. This kind of solution is acidic. A base is a substance that accepts hydrogen ions. When a base is dissolved in water, the balance between hydrogen ions and hydroxide ions shifts the opposite way. An acid is a substance that donates protons (in the Brønsted-Lowry definition) or accepts a pair of valence electrons to form a bond (in the Lewis definition).
