connected to 230V for 5minute​

Answer 1

Answer:

Heat = W = Pt = 500×5×60 =

150000 j

hope it helps...

Answer 2

Given - Power and time

Find - Heat energy produced

Solution - Heat energy produced can be calculated by the formula- Power*time

As per the known fact, 1 min = 60 seconds

So, 5 min = 60*5

Performing multiplication

5 min = 300 seconds

Keep the values in formula

Heat energy produced = 500*300

Performing multiplication

Heat energy produced = 1.5*10⁵ Joules

Hence, the heat energy produced is 1.5*10⁵ Joules.
