Answer: B. Rapid growth in technology led to the development of new tools and machines.
Explanation: During the Industrial Revolution, which took place from the 18th to the 19th century, there was a significant increase in technological advancements. This led to the development of new tools, like the spinning jenny and power loom, and machines, such as the steam engine, that revolutionized the way work was done.
Before the Industrial Revolution, most work was performed manually and was often difficult and slow. However, with the introduction of new technologies, such as mechanized production methods, work became more efficient and productive.
For example, the invention of the steam engine by James Watt allowed factories to power machinery, which greatly increased production capabilities.
These technological advancements not only improved productivity but also had far-reaching effects on society as a whole. They led to the growth of factories, urbanization, and the emergence of a new working class.

A NOR RS flip-flop's S input is changed to logic-1 and its R input is changed to logic-0. What will its Q NOT output do
A NOR RS flip-flop's S input is changed to logic-1 and its R input is changed to logic-0. remain at logic 1 will its Q NOT output do.
The output state of the RS flip-flop is what when S 1 and r 0?
S=1 and R=0: Q'=0 is the output value of the bottom NOR gate. Thus, the top NOR gate's inputs are both equal to one, and Q is therefore 1.
Consequently, the flipflop is set to Q=1 when the inputs S=1 and R=0 are combined. S=0 and R=1: The outputs become Q=0 and Q'=1, which are analogous to the previous arguments.
What will the output be when s 0 r 0?
A NAND-based S-R latch is said to be in an ambiguous or forbidden state if S'=0 and R'=0, which causes both outputs (Q and Q') to go HIGH. The system enters an unanticipated circumstance, which is why this state is also referred to as an invalid state.
