Correct Answer: Joule's

Solution : The correct option is Joule's.

According to Joule's Law, the heat produced by an electric current (I) flowing through a conductor is directly proportional to the resistance of the conductor (R), the square of the current (I²), and the time (t) for which the current flows. Mathematically, Joule's Law is expressed as:

H = I^{2 .} R ^. t

Correct Answer: Q is the maternal grandfather of S

Solution : Given:
A + B⇒A is the father of B
A – B⇒A is the wife of B
A × B⇒A is the brother of B
A ÷ B⇒A is the son of B
M × R × Q + F + S – D ÷ U

As per the given information family tree will be as follows –

Here, the quadrilateral represents the male and the circular figure represents the female in the figure.

So, Q is the maternal grandfather of S is not true. Hence, the first option is correct.

Correct Answer: Negative

Solution : According to the law of demand, the quantity bought varies inversely with the price. In other words, the quantity demanded decreases as the price increases. Because of declining marginal utility, this happens.

Correct Answer: Michael Faraday

Solution : The correct option is Michael Faraday.

Michael Faraday formulated the laws in the 1830s. According to Faraday's laws, the amounts of different substances liberated (deposited or evolved) during electrolysis are directly proportional to their chemical equivalent weights when the same quantity of electricity passes through the electrolytic solution.
