P=5.0 x 120

P=600 watts
P=E/t
E=Pt
E=600 J/s x 55.0
E=33,000 J

thank you so much, Ms. Sue

P = E*I = 120 * 5 = 600 Watts = 600 J/s.

Energy = P*t = 600J/s * 55s = 33,000 J.

thank you so much Sir Henry

Glad I could help.

To calculate the energy given off by the toaster, we need to use the formula:

Energy = Power x Time

First, let's calculate the power (P) of the toaster using the formula:

Power = Voltage x Current

Given that the voltage (V) is 120V and the current (I) is 5.0A, we can substitute those values into the formula:

Power = 120V x 5.0A = 600W

So, the power of the toaster is 600 Watts.

Now, we can calculate the energy given off by the toaster using the formula:

Energy = Power x Time

Given that the time (t) is 55.0 seconds, we can substitute the values into the formula:

Energy = 600W x 55.0s

Calculating:

Energy = 33000 Joules

Therefore, the toaster gives off 33000 Joules of energy in 55.0 seconds.
