Vwould radiation with a wavelength 0.91 nm or a frequency of 5.9×1011 s−1 be detected by an x-ray detector? would radiation with a wavelength 0.91 or a frequency of 5.9×1011 be detected by an x-ray detector? only the radiation with a wavelength 0.91 nm can be observed by an x-ray detector. only the radiation with a frequency of 5.9×1011 s−1 can be observed by an x-ray detector. both types of radiation can be observed by an x-ray detector. neither type of radiation can be observed by an x-ray detector.

Only the radiation with a wavelength 0.91 nm can be observed by an X-ray detector.

Explanation:

To answer this question we need to consult the ranges in which x rays are in the electromagnetic spectrum:

The X radiation in the electromagnetic spectrum fall in the region of:

frequency: 3 x 10¹⁶ Hz  to 3 x 10¹⁹ Hz     (1Hz = 1s⁻¹)

wavelengt: 1 pm  to 10 nm

Comparing the values in our question,

0.91 nm will be detected

5.9 x 10¹¹ Hz will not be detected.

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
