Answer 1

Ответ:

прости если так долго я старался

Answer 2

Calculating the Time Taken for the Kettle to Work

To calculate the time taken for the kettle to work, we can use the formula:

Work (Joules) = Voltage (Volts) × Current (Amperes) × Time (Seconds)

Given: - Voltage (V) = 207V - Current (I) = 6A - Work (W) = 298080J

We can rearrange the formula to solve for time (T):

Time (T) = Work (W) / (Voltage (V) × Current (I))

Substitute the given values into the formula to find the time taken for the kettle to work.

Time (T) = 298080J / (207V × 6A)

Calculating the time:

Time (T) = 298080J / (1242VA)

Time (T) ≈ 240 seconds

Therefore, the time taken for the kettle to work, when connected to an electrical circuit with a voltage of 207V and a current of 6A, is approximately 240 seconds.
