Studies of the relationship of the Sun to our galaxy-the Milky Way-have revealed that the Sun is located near the outer edge of

lianna [129]

Mass of the milkyway galaxy :

$M_{mw} = \frac{4\pi ^{2}r^{3}}{GT^{2}}\\\\M_{mw} = \frac{4\pi ^{2}(3x10^{4}x9.46x10^{15})^{3}}{6.67x10^{-11}Nm^{2}/Kg^{2}x(7.13x10^{15})^2}\\\\M_{mw } = 2.7x10^{14} Kg$

The magnitude of the mass of the Milky Way galaxy = $2.7x10^{14} Kg$

<h3>Can galaxies recycle stars?</h3>

Galaxies do not appear to have sufficient matter inside them to keep shaping modern stars at the rates that they do. Presently, astronomers have caught a universe within the act of reusing fabric that it already tossed out, which may clarify the discrepancy. New perceptions give the primary coordinate evidence of gas streaming into distant galaxies that are effectively making infant stars, offering support for the "galactic recycling" theory.

Learning Goal: To understand the concepts explaining the operation of transformers.

Alex

Answer:

Part a)

ZERO

Part b)

N = 10 turns

Explanation:

Part a)

As we know that transformer is used to change the input voltage into required output voltage

Here this input and output is considered only when it will change with time as the whole concept is based upon Faraday's law where we need to change the flux with time.

So if we have input Source is DC source then output voltage will be zero as there is no flux change

Part b)

As we know by the principle of transformer

$\frac{V_1}{V_2} = \frac{N_1}{N_2}$

$\frac{500}{25} = \frac{200}{N_2}$

$N_2 = 10$

so total number of turns in secondary coil must be 10

PV System for the Smith Family answers

Pavel [41]

<span>System B: The amorphous silicon solar modules have an efficiency of 6%. The dimensions of the solar modules amount to 0.5m by 1.0m. The output of each module is 30 Wp. The modules cost 20€ each. The advanage of the amorphous silicon solar modules is that they perform better on cloudy days in which there is no direct sunlight. Installed in the Netherlands, this system gives, on a yearly basis, 10% more output per installed Wp than the multicrystalline silicon modules. </span>
<span>System A: The efficiency of the multicrystalline silicon module amounts to 15%. The dimensions of the solar module are 0.5m by 1.0m. Each module has 75 Wp output. The modules cost 60€ each.

An object is dropped from a height of 75.0 m above ground level. (a) determine the distance traveled during the first second.

barxatty [35]

The relevant formula we can use in this case would be:

h = v0 t + 0.5 g t^2

where,

h = height or distance travelled

v0 = initial velocity = 0 since it was dropped

t = time = 1 seconds

g = 9.8 m/s^2

So calculating for height h:

h = 0 + 0.5 * 9.8 m/s^2 * (1 s)^2

<span>h = 4.9 meters</span>
