Is this really a college course? I can only say I hope the problems are going to get harder!

What do you think the "h" in kWh stands for?

You got 5 correct: 1 kW for 10 hours= 10 kWh of electrical energy.

Now think: 5 kW for how many hours= 10 kWh (In other words: 5 times what equals 10!) (that's number 4.)

Number 3, "10 ____3____ for 1 hour" is asking for the units.
10 *1= 10 so what units times hours gives kWh?
