Answer:
6.34 x 19^14 Hz
Explanation:
Wavelength, λ = 473 nm = 473 x 10^-9 m
the relation between the frequency and the wavelength is given by
v = f x λ
where, v is the velocity of light in vacuum which is equal to 3 x 10^8 m/s.
So, f = v / λ
f = ( 3 x 10^8) / ( 473 x 10^-9)
f = 6.34 x 19^14 Hz
Answer:
h = 206.4 m
range = 515.9 m
Explanation:
from the question we are given the following:
initial velocity (u) = 75 m/s
angle above surface = 58 degrees
acceleration due to gravity (g) = 9.8 m/s^{2}
find the maximum height (h) and the horizontal distance
maximum height (h) = 
h = 
h = 206.4 m
the horizontal distance here is the range
range = 
range = 
range = 515.9 m
Explanation:
Plasma can conduct electricity because plasma consists of electrically charged particles called ions, instead of uncharged particles such as atoms or molecules.
<span>The correct answer is: Mechanical Energy
Explanation:
As the guitar strings are plunked, the potential energy stored in the strings has an ability to make them vibrate. When the strings are vibrating, that potential energy is actually converted to the kinetic energy. Hence, the whole phenomena contains both the kinetic energy and the potential energy. The sum of kinetic energy and the potential energy is called Mechanical energy. Therefore, the correct answer is Mechanical Energy.</span>
