Answer :
Final answer:
The light bulb does 3000 joules of work when it is lit for 30 seconds.
Explanation:
To calculate the work done by a 100-W lightbulb when it is lit for 30 seconds, we use the relationship between power (P), work (or energy), and time (t). Power is defined as the rate at which work is done or energy is transferred. Therefore, work or energy (E) can be calculated using the formula: E = P * t, where P is power in watts (W) and t is time in seconds (s).
To generate an accurate answer for the given question, we will use the stated power of the lightbulb (100 W) and the time duration (30 seconds). Thus, the energy used by the lightbulb is:
E = 100 W * 30 s = 3000 joules (J)
The lightbulb thus does 3000 joules of work when it is lit for 30 seconds.
