Velocity = fλ
where f is frequency in Hz, and λ is wavelength in meters.
2.04 * 10⁸ m/s = 5.09 * 10¹⁴ Hz * λ
(2.04 * 10⁸ m/s) / (5.09 * 10¹⁴ Hz ) = λ
4.007*10⁻⁷ m = λ
The wavelength of the yellow light = 4.007*10⁻⁷ m
I believe it is A bit not completely sure
The answer for this is actually b. 79 m/s
I submitted it to odyssey-ware and i got the question correct
The answer is the electron microscope. It is a kind of
microscope that uses electrons to light a sample and make an enlarged
image. These kinds of microscopes have much better determining
power than light microscopes and can get much higher magnifications.
Answer:
<h3>8. </h3>
m= 0. 113 kg
W = 1.1074 N
g = 9.8 m/ s²
<h3>9. </h3>
m= 870 kg
W = 8526 N
g = 9.8 m/s²
<h3>10.</h3>
a) weight on earth:
weight = mass × acceleration due to gravity (g)
<em>g</em><em> </em><em>on</em><em> </em><em>earth</em><em> </em><em>=</em><em> </em><em>9</em><em>.</em><em>8</em><em> </em><em>m</em><em>/</em><em>s</em><em>²</em>
W = 75 × 9.8
<u>W</u><u> </u><u>= </u><u>7</u><u>3</u><u>5</u><u> </u><u>N</u>
b) g on Mars
285 = 75 × g
g = 285/ 75
<u>g = 3.8 m/ s²</u>
