Speed = 50.4 m/s
Time = 0.25 s

Distance  =  (speed) x (time)  =  (50.4 m/s) x (0.25 s)  =  12.6 meters.

What is the thinnest film of a coating with n = 1.39 on glass (n=1.52) for which destructive interference of the red component (
Illusion [34]
In optics, you have to create a layer of coating that is approximately 1/4 of the light's wavelength. The working equation for this problem is:

d = λ₀/4n, 
where
λ₀ is the wavelength of the incident light
n is the refractive index of the coating

Substituting the values,

d = (650 nm)/4(1.39)
<em>d = 116.9 nm</em>

zmey [24]

Answer:

The divergence on the sensor shows the magnitude of the charges

Explanation:

This will increase as length increases since it is said to be proportional to the length. note that test charge is always positive and charge on the grid is positive as indicated (1 nC)

Lc circuit consists of a 20.0 mh inductor and a 0.150 µf capacitor. if the maximum instantaneous current is 0.400 a, what is the
slavikrds [6]
The following expression is applicable:

Max. inductor energy = Max. capacitor energy

Where;
Max. inductor energy = LI^2/2, with L = 20.0 mH, I = 0.400 A
Max. capacitor energy = CV_max^2/2, C = 0.150 micro Faraday, V_max = Max. potential difference

Substituting;
LI^2/2 = CV^2/2
LI^2 = CV^2
V^2 = (LI^2)/C
V_max = Sqrt [(LI^2)/C] = Sqrt [(20*10^-3*0.4^2)/(0.15*10^-6)] = 146.06 V

-Dominant- [34]

Answer: Forensic science

In early 1800s, the professional investigators regularly attend court trial to answer questions related to physical evidence, which is described as forensic science. The study of physical evidence is a practical tool to assist police in conducting investigations by developing a sense of how the crime was committed. Therefore, the application of forensic science is a great help in solving crime.
