Answer:

30000 J

Explanation:

Power is defined as the amount of work done per unit time:

$P=\frac{W}{t}$

where

P is the power

W is the work done

t is the time taken

In this problem, we know the power of the microwave oven: $P=1000 W$ , and we are asked to find the work done in a time of $t=30 s$ , so by re-arranging the equation we find:

$W=Pt=(1000 W)(30 s)=30,000 J=30 kJ$

When light passes through an object unchanged, scientists call that process _____.

<u>Answer</u>:

When light passes through an object unchanged, scientists call that process Transmission.

<u>Explanation</u>:

Transmission is the process where all the light that is passed through the material moves via the material without being absorbed. The Transmission depends on the affected radiation.The Transmittance of the medium is defined as the ratio between transmitted radiant power and incident radiant power. The light that is passed through the medium and not reflected will be either scattered or reflected. The light can be transmitted only through transparent or translucent material. Opaque object does not allows transmission of light.
