Suppose you bake a potato in a toaster oven that uses 1.2 kW. The oven is turned on for 25 minutes. How many kilowatt hours did it use?

0.3kilowatts hours

Explanation:

If you bake a potato in a toaster oven that uses 1.2 kW and oven turned on for 25minutes, to get the amount in kilowatt hour, we will need to convert minutes to hour first

60minutes = 1hr

25minutes = x

60x = 25

x = 25/60 hr

x =

Multiply the time in hr with the power

Amount of kWhr used = 1.2 * 25/60

Amount of kWhr used = 30/60

Amount of kWhr used  = 0.3kilowatts hours

Hence it used 0.3kilowatts hours

Independent variable: the best method to get rid of them.

Dependent variable: washing with soap and water.

Hypothesis: Organic oils

Control group: water

Answer:

Step-by-step explanation:

Time taken by the tomatoes to each the ground

using h = 1/2 g t^2 

t^2 = 2h/g = 2 x 50/ 9.8 = 10.2

t = 3.2 sec 

horizontal ditance = speed x time = 3 x 3.2 = 9.6 meters

The question specifies the diameter of the screw, therefore the IMA of this screw is 0.812? / 0.318 = 8.02
