The cost of using 14,400 watts hour would be $43.2.
<h3>What is Energy ?</h3>
Energy is defined as the capacity to do work.
It is given in the question that
A 1600 watts electric oven is used for 9 hours
Power * Time
power = 1600 watts
Time = 9 hours
Total energy consumed = 1600 watts * 9 hours
= 14,400 watts hour
energy is measured in Kilowatts hour
= 14,440 watts hour
14,440/1000 kwh
= 14.4 kwh
It is given that the cost per unit of energy is $3.00 per kwh
Therefore , the cost of using 14,400 watts hour would be 14.4 * 3
= $43.2
The function of Voltmeter and Ammeter is to measure Voltage and Current respectively.

The cell model/theory is a big one
the atomic model/theory
Answer:
3
Explanation:
For an ideal ramp, M.A/V.R = 1 where M.A = mechanical advantage and V.R = velocity ratio.
Now, V.R = distance moved by effort, d'/distance moved by load, d = d'/d
Now, d' = 3 m and d = 1 m.
So, V.R = d'/d = 3 m/1 m = 3
From M.A/V.R = 1
M.A = V.R = 3
So, the ideal mechanical advantage of the ramp M.A = 3
