There is a missing data in the text of the problem: the current drawn is 0.5 A (found on internet)

Solution:
The power used by the toaster is the product between the voltage V and the current I:
P=VI=(132 V)(0.5 A)=66 W=0.066 kW

The toaster is used for a time of 2 hours: t=2h, therefore the energy used is equal to
E=Pt =(0.066 kW)(2 h)=0.132 kWh

Let w(x)=3x-7.If w(x)=14, find x
dlinn [17]

Answer:

7

Explanation:

We are given:

    w(x) = 3x   -   7

     w(x)  = 14

The problem here entails us to solve for x;

To solve for x; equate the two expressions:

         

          3x  - 7  = 14

           3x  = 14 + 7

           3x  = 21  

             x = 7

So the value of x  = 7

Complete the following sentence: The term coherence relates to the phase relationship between two waves. the polarization state
77julia77 [94]

Answer:

<em>the phase relationship between two waves.</em>

<em></em>

Explanation:

Coherence describes all properties of the correlation between physical quantities between waves. It is an ideal property of waves that determines their interference. In a situation in which there is a correlation or phase relationship between two waves. If the properties of one of the waves can be measure directly, then, some of the properties of the other wave can be calculated.
