How many watts does a flashlight that has 6.00 x 102 C pass through it in 0.500 h use if its voltage is 3.00 V? Which is faster, light or electricity? What are Spectral lines? What is the law of reflection? What is the electric power of a lamp that carries 1 A at 120 V?
What are Spectral lines? What are the fundamentals of electronics? What do you mean by sextant? What detector is used to pick up the x-rays in hospitals? What is a spectrum ? What is the expanded form of LASER? What are the reasons for preferring diode lasers as light sources for opti...
we don’t know if dark energy has the effect of any type of force at all. There are many ideas floating around about what dark energy could possibly be. Here are four leading explanations for dark energy. Keep in mind that it’s possible it’s something...
In PET/CT, the photosensors and readout electronics as well as the cooling infrastructure are placed radially behind the scintillation crystals (c.f. Fig.1). This enables short-axial FOV units, that can be extended to long aFOV systems by adding multiple copies of such ring-shaped gantries....

While the sun's light includes all colors, they don't all come in equal amounts. The sun emits radiation through a process known as black body radiation. In physics, a black body is an object that does not reflect any light but emits radiation solely due to its thermal energy. ...
where the PET detectors are normally placed between the gradient coils and the body coil of the MRI scanner (c.f. Fig.2), the radial space is extremely constrained. Therefore, reducing the infrastructure for electronic circuits as well as cutting back on the amount of communication lines and ...

(the spectral lines are blueshifted by the Doppler effect) while the other is receding (lines redshifted), a clear indication that the disk is rotating. The rotation speed is about 550 kilometers per second or 1.2 million miles per hour. Such a high rotation speed is evidence that there ...
continuous, but “quantized”. These levels are thus labeled with the quantum numbern(n=1, 2, 3, etc.) which he claimed could be determined using theRyberg formula– a rule formulated in 1888 by Swedish physicist Johannes Ryberg to describe the wavelengths of spectral lines of many chemical...
