Charge given, Q = 96000 C
Time given (t) = 1 hour =60 × 60 s = 3600 s
2 hour = 2 (3600) = 7200
Voltage (V) = 40 V
We know that, current can be found out by using the formula,
{tex}\begin{array} { c } { I = \frac { Q } { t } } \\\\ { I = \frac { 96000 } { 7200 } = \frac { 80 } { 6 }= \frac { 40 } { 3 } A } \end{array}{/tex}
Amount of heat generated can be found out using the formula,
{tex}\begin{array} { c } { \mathbf { H } = \mathbf { V I t } } \\\\ { = 40 \times \frac { 40 } { 3 } \times 7200 } \\\\ { = 384000 \mathrm { J } } \\\\ { = 3.84 \times 10 ^ { 6 } \mathrm { J } } \end{array}{/tex}
Thus, the “amount of heat” generated is {tex}3.84\times10^6 J{/tex}

In the story " The snake and the Mirrors", the homeopath doctor has been portrayed as a person who can assess himself critically and humorously .He honestly admits that as a new practitioner of medicine, he could not earn much and had to rent a poor, rat- infested house without even the facility of electricity. He also admits a funny intent that he wanted to marry a fat and rich lady - doctor as it would help him run away without getting caught when he would make some silly mistake .This witty side of the doctor is seen again at the end of the story when he remarks that the thief did not take away his dirty vest because he had a sense of cleanliness.

- Galvanisation is a method of protecting steel and iron from rusting by coating them with a thin layer of zinc.
- Alloying: An alloy is a homogeneous mixture of two or more metals or a metal and a non-metal in a definite proportion. The resultant metals, called alloys do not corrode easily.
For example: Brass (copper and zinc), Bronze (copper and tin) and stainless steel (iron, nickel, chromium and carbon).

Bandwagoning in international relations occurs when a state aligns with a stronger, adversarial power and concedes that the stronger adversary-turned-partner disproportionately gains in the spoils they conquer together. Bandwagoning, therefore, is a strategy employed by states that find themselves in a weak position.
