Solution,
[tex]p = \frac{w}{t} \\ or \: 30 = \frac{1200}{t} \\ or \: 30 \times t = 1200 \\ or \: t = \frac{1200}{30} \\ t = 40 \: seconds[/tex]
Hope this helps..
Good luck on your assignment.
Answer:
40 seconds
Explanation:
Time (measured in seconds) = Work Done (measured in Joules) / Power (measured in Watts)
Time (s) = 1200/30
Time (s) = 40
It will take 40 seconds for a 30W light bulb to transfer 1200J of energy.
