Answer:
The relationship between voltage, current, and resistance is described by Ohm's law. This equation, i = v/r, tells us that the current, i, flowing through a circuit is directly proportional to the voltage, v, and inversely proportional to the resistance, r.
The answer is Column, however if you want to know the scientific word for it, it is also known as a group
(extra fact, a row is called a period)
The correct answer is 1.25 because it is 1/2 of 1 1/2 and that is 1.25.
Answer:
Explanation:
(a) Work done, W = 1.82 x 10^4 J
(b) internal energy, U = - 4.07 x 10^4 J ( as it decreases)
(c) According to the first law of thermodynamics
Q = W + U
Q = 1.82 x 10^4 - 4.07 x 10^4
Q = - 2.25 x 10^4 J
The frequency is 
and it is blue light
Explanation:
The relationship between the speed, the frequency and the wavelength of an electromagnetic wave is given by:
where
is the speed of light
f is the frequency of the wave
is its wavelength
In this problem, the wavelength of the wave is
Therefore, its frequency is:
The wavelength of this wave is
And by looking at the table of the wavelengths of the colors, we notice that this corresponds to the blue light, which has a range of wavelength of
[450 - 495] nm
