Answer:
weeds out the weak, sick, and old by killing them
The speed of electromagnetic waves in a vacuum is the same as the speed of light. It can be measured by finding the frequency and wavelength of two different waves, and then by that correlation, the speed of the waveform.
Hope this helps you (:
Answer:
The work done is equal to zero = 0
Explanation:
Let us remember that the definition of physical work is given by the product of force by the displacement of the body.
![Work=F*d\\\\where\\F= force [N]\\d=distance [m]\\replacing\\Work=1115*(0) = 0](https://tex.z-dn.net/?f=Work%3DF%2Ad%5C%5C%5C%5Cwhere%5C%5CF%3D%20force%20%5BN%5D%5C%5Cd%3Ddistance%20%5Bm%5D%5C%5Creplacing%5C%5CWork%3D1115%2A%280%29%20%3D%200)
