Answer:
2.3)X10^13-Hz
Explanation:
What’s the frequency of radiation that has a wavelength of 13 um, about the size of bacterium?
a micro meter is 10^-6 meter
frequency of light times wavelength = c the speed of light 3X10^8 M/sec
so
frequency times 13 X10^-6 =3X10^8 M/
so
FR3EQUENCY = 3X10^8/13X10-6
=(30/13)10^13 =2.3)X10^13-Hz

the answer is a
it carries down heat rays which evaporates the water.
A:The half-life should be similar to the age of the object.
Explanation:
Hopefully this helps!
I believe it would be the 2nd one, “increasing the area of their contact”.
