Diverging Lenses - Object-Image Relations

The Mathematics of Lenses

Ray diagrams can be used to determine the image location, size, orientation and type of image formed of objects when placed at a given location in front of a lens. The use of these diagrams was demonstrated earlier in Lesson 5 for both converging and diverging lenses. Ray diagrams provide useful information about object-image relationships, yet fail to provide the information in a quantitative form. While a ray diagram may help one determine the approximate location and size of the image, it will not provide numerical information about image distance and image size. To obtain this type of numerical information, it is necessary to use the Lens Equation and the Magnification Equation. The lens equation expresses the quantitative relationship between the object distance (do), the image distance (di), and the focal length (f)

An electric toaster is rated 1200 watts at 120 volts. what is the total electrical energy used to operate the toaster for 30 sec
Tresset [83]

Answer : Total electrical energy is 36000 J.

Explanation :

It is given that,

Power of electric toaster, P = 1200 Watts

Voltage, V = 120 Volts

Time, t = 30 s

Electric energy is defined as the product of the power and the time taken.

E=Pt

E=1200\ W\times 30\ s

E=36000\ J

Total electrical energy used to operate the toaster for 30 seconds is 36000 J.

What is the voltage of this circuit.
liberstina [14]

Answer:

110.4 v

Explanation:

Find the equivalent resistance of the two parallel circuits

R1 and R2 in parallel   =   R1 * R2 / (R1+ R2) =   <u>1 ohm </u>

 similarly R4 and R5 =  <u>4.77 ohms</u>

Now you can add the three resistances into one  (R3=10)

    1 ohm + 10 ohm + 4.77 ohm = 15.77 ohms

Now

V = IR

V =  7 amps  * 15.77 ohm = 110.4 v
