Please explain in simple terms why a purple flower appears purple when a white light shines on it?

1 answer:

6 0

The white light is made up of all wavelength of electromagnetic spectrum, the spectrum has different colors, When light rays fall on an object, some of the color in the white light will be absorbed by the object while some will be reflected. The color that is reflected by the object is the one that an observe will see. Thus, a purple flower will appear purple because it is reflecting the wavelength that appear as purple

Suppose your local apparent solar time is 11 am, and you have a clock that says it is noon in Greenwich. What is your longitude

jeyben [28]

The longitude based on the time difference is 15 degrees.

<h3>Longitude of complete rotation of the Earth</h3>

The longitude of a complete rotation of the earth in a 24 hours is calculated as follows;

$= \frac{360^0}{24} = 15^0 \ of \ longitude$

<h3>Time difference</h3>

The time difference between the local apparent solar time and the Greenwich time is calculated as follows;

$t = 12 pm \ - \ 11 am\\\\t = 1 \ hour$

Since it is one hour time difference, the longitude is 15 degrees.

What is the power of a machine that pushes with a force of 3 n for a distance of 9 m in 8 s?

dalvyx [7]

The work done by the machine is equal to the product between the force applied and the distance over which the force is applieds, so in this case:
$W=Fd=(3 N)(9 m)=27 J$

And the power of the machine is equal to the ratio between the work done by the machine and the time taken:
$P= \frac{W}{t}= \frac{27 J}{8 s}=3.38 W$
