Λ = 3*10^8 / 9*10^8 = 1/3 m
no. of wavelengths = 60/(1/3) = 180
-- If the frequency of a wave is too high for our eyes to detect it ... but not <u>too too</u> high ... we call it an <em>ultraviolet </em>wave.
-- If the wave's frequency is even higher than that, we call it an <em>X-ray</em> wave.
-- If the wave's frequency is even higher than that, we call it a <em>Gamma Ray </em>wave.
Answer:
Explanation:
From the question, acceleration from 
in 10 seconds.
Acceleration function can be written as:-
From the acceleration equation, we can obtain the velocity equation:
We calculate velocity after 10sec from the above v(t) as 
.
To obtain distance travelled after 10 seconds:-
Therefore 200m is for 10seconds, and next 200m at 30m/s
Total time=
Based on scientific records, a charm quark has a charge that's approximately equal to: 2) 1.07 × 10⁻¹⁹ C.
<h3>What is a charge?</h3>
A charge simply refers to a fundamental, physical property of matter that governs how the particles of a substance are affected by an electromagnetic field, especially due to the presence of an electrostatic force (F).
Also, charge is typically measured in Coulombs and a charm quark (elementary particle) has a charge that's approximately equal to 1.07 × 10⁻¹⁹ Coulomb.

Answer:
Absorbed and reflected
Explanation:
B is reflected because you can’t see the red arrow which represents a light that bounces off of it and a aired up sword because you can see it win through the object shown in the picture
