Cosmic, or background, radiation is the small amount of high energy radiation which is mostly left over from the big bang or from supernovas. It is mostly single protons, but also alpha particles and even sometimes heavier elements. It can also refer to the low levels of electromagnetic radiation present all over the universe.
Answer:
16∠45° Ω
Explanation:
Applying,
Z = V/I................... Equation 1
Where Z = Impedance, V = Voltage output, I = current input.
Given: V = 120cos(10t+75°), = 120∠75°, I = 7.5cos(10t+30) = 7.5∠30°
Substitute these values into equation 1
Z = 120cos(10t+75°)/7.5cos(10t+30)
Z = 120∠75°/ 7.5∠30°
Z = 16∠(75°-30)
Z = 16∠45° Ω
Hence the impedance of the linear network is 16∠45° Ω
The answer is c to take a pictures with the camera in the metal hall
Answer:
Oceanic Crust/Continental Crust
Explanation:
It is a destructive plate boundary between the oceanic crust of the Nazca plate and the continental crust of the South American plate.
(a)The window panes are transparent
(b)The colors of the panes are due to the wavelengths of light that the glass allows to pass through.
<h3>What are trasparent glasses?</h3>
The glasses which allows the light rays to pass through them are called as the transparent glasses.
or visible light is electromagnetic radiation within the portion of the electromagnetic spectrum that is perceived by the human eye.[1] Visible light is usually defined as having wavelengths in the range of 400–700 nanometres (nm),
corresponding to frequencies of 750-420 terahertz, between the infrared (with longer wavelengths) and the ultraviolet (with shorter wavelengths
Hence the window panes are transparent the colors of the panes are due to the wavelengths of light that the glass allows to pass through.
