Answer:
The laptop is overheated
Explanation:
computers need to be on a flat surface otherwise they may begin to overheat and begin to make a humming sound. This humming sound is the computer releasing air sort of like breathing.
The mass of the scale pan : 0.11 kg
<h3>Further explanation</h3>
Given
A spiral spring's length = 20 cm
mass 50 g ⇒ the length = 22 cm
mass 70 g ⇒ the length = 22.25 cm
Required
the mass of the scale pan
Solution
Hooke's Law :
The spring constant (k) :
mass of the scale pan=m(for 50 g mass) :
I believe the answer is 7.24 kJ.
From the equation ΔE = dW + dQ; where W is the work done on/by the system and Q is the heat the system absorbs/loses.
Therefore; ΔE = 72.4 kJ since the system has bot done any p-v work (dV= zero) and has absorbed heat.
Answer:
Transferred
Explanation:
It only changes from one state to another
C
The wavelength of the light produced by the laser is determined by the Composition of the active medium
Explanation:
As stipulated by Bohr's theory, different atoms have different and unique absorption and emission spectra that can also be used to identify them. The electrons of the atoms when excited (the enter an inversion state), using specific photons of electromagnetic waves, they move up energy levels. When the electrons move back to their ground state, they release the same wavelength of photons. The photos then excite other atoms and the amplification continues. Therefore the lasing medium is the main determinant of the wavelength of the laser beam.
For example, the use of argon fluoride as an active medium produces lasers of 193 nm in wavelength and the use of nitrogen produces laser of
