Answer:
Explanation:
For this particular problem, we are going to use the non-relativistic Doppler effect which, is the change in frequency of a wave concerning an observer who's moving relative to the wave source. The shifted wavelength is:
,
where is the wavelenght as it comes from the source, is the velocity of the source (the quasar) and, is the velocity of the wave. In this case, the velocity of the wave is the speed of light, .
Solving for ,
,
now computing
,
The velocity of the quasar is negative because it is getting close to the Earth!
Carrying capacity is the maximum amount of people that our planet can support indefinitely. It will impact our future because we will have to work around it and figure out a solution.
Out of the 3 types of heat transfer, this scenario would be most likely to be an example of convection.
Convection is where the transferring of heat is resulted through the movements of fluid, but in this case it is air. What happens is that when a part of the whole mass of air is heated, the hotter air rises and the cooler air descends and takes place of the hotter air before it was heated. Then, the cooler air becomes hotter and the hotter air before becomes the cooler air of both, which then results to the repeat of the exchange of places. This creates a motion until the whole mass has achieved mutual temperature, the heat source has stopped or extinguished, or there is a shift of temperature.
Answer:
273 dots/inch
Explanation:
We are given:
•Average wavelength = 555mm
•d = 3.5mm
• distance = 48cm
Let's use the Reyleigh formula:
∅ = 1.22
Substituting figures in the formula, we have:
From the formula above, we get:
∅ = x/d
where x is distance btw dots and pupil
Solving for x we get:
x =∅d
To calculate dots per inch(dpi), we use:
We already know 1 inch =2.54cm
Therefore,
273 dots/inch
