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

Answer:
segment 4
Explanation:
Its segment 4 because even though they only traveled 55(km) its only been 1 hour. Every other one took ether 1 hour and 5 minutes or 2 hours.(this is my honest opinion im sorry if its wrong)
We know that the equation for density is:
where D is the density, m is the mass in g, and V is the volume in either mL or cubic centimeters.
So then, given two of the variables, we can solve for density:
Therefore, the density of the bread is 0.6g per cubic centimeter.
