Find the correct statementa)1 Gigawatt is equal to 109Wb)power is the ...
Power is the rate at which work is done. It is a measure of how quickly energy is transferred or converted. The SI unit of power is the watt (W), which is equal to one joule per second.
The correct statement is option C, which states that both statements a and b are true. Let's break down both statements to understand why they are correct:
a) 1 Gigawatt is equal to 10^9 Watts:
- The prefix "Giga" in the SI system represents a factor of 10^9 (1,000,000,000). So, when we say 1 Gigawatt, it means 1,000,000,000 Watts. Therefore, statement a is true.
b) Power is the rate of doing work:
- Power is defined as the amount of work done or energy transferred per unit time. It measures how quickly work is done. The formula for power is given by P = W/t, where P is power, W is work, and t is time. So, statement b is also true.
c) Both statements a and b are true:
- Since both statements a and b are individually true, the correct answer is option C, which states that both statements are true.
In conclusion, statement a is true because 1 Gigawatt is equal to 10^9 Watts, and statement b is true because power is indeed the rate at which work is done. Therefore, the correct answer is option C.
