PLEASE HELP ASAP 98 POINTS!!!!!!! ALL I NEED YOU GUYS TO DO IS WRITE A ONE PARAGRAPH REFLECTION ON ECLIPSES AND WRITE IT AS IF Y

OU WHERE EXPLAINING IT TO A FRIEND
HERE IS A BETTER WAY TO EXPLAIN IT
Provide a description of how you made your model and how it demonstrates eclipses or lunar phases.
Include a one-paragraph reflection on the success of your model in explaining your event.

DON'T WORRY ABOUT THE MODEL I HAVE IT COVERED.

A eclipse starts when one object in space is blocking an observer. Most commonly known as the moon blocking the sun. For us having a visual on eclipses we normally have two eclipses. We have the solar eclipse and the lunar eclipse. These are both very important on the timing and the cycles of the moon. A solar eclipse happens when the moon moves in front of the sun. This will cause a shadow to fall on only a few certain places on earth. Then a lunar eclipse is when the Sun, moon, and earth are perfectly aligned. With the earth being the middle the Sun casts its rays and causes a huge shadow on the moon.

Hope this helped!

check out my model showing the sun, earth n moon. u can see as the moon moves around the earth, its path is at a angle w earth's path around the sun. so moon's reflection of sunlight as seen from earth changes every night. it is called lunar phases: going crescent moon to full moon n back. eclipse happens when earth is between sun and moon and blocks part of the sun light. earth's shadow covers part or all of the moon. it is called lunar eclipse.

A thin film of oil of thickness t is floating on water. The oil has index of refraction no = 1.4. There is air above the oil. Wh
vesna_86 [32]

Answer:t=0.1205

Explanation:

Given

Refractive index of oil\left ( \mu \right )=1.4

Wavelength of red light =675 mm

Condition for constructive interference is

2\mu _{oil}t=\frac{m\lambda }{2}

t=\frac{m\lambda }{4\mu _{oil}}

For m= 1 i.e. for minimum thickness

t=\frac{1\times 675\times 10^{-9}}{4\times 1.4}

t=0.1205 \mu m

Answer:

0.94m/s (squared)

Explanation:

a=change in velocity/time

a=v-u/t

a=32-0=32/32

A hydraulic press must be used to press-fit two components together in an assembly process. the system must generate at least 77
Kobotan [32]
The pressure generated by the piston at the input cylinder must be:

p = F / A = 250 lb-f / 30 in^2


The pressure generated by the piston at the output cylinders is p = F / A = 775 lb-f / A.


Pascal principle rules that both pressures are equal, so:


250 lb-f / 30 in^2 = 775 lb-f / A => A = 775 lb-f * 30 in^2 / 250 lb-f = 93 in^2


Gvien that each output cylinder are 30in^2 you need 93 / 30 = 3.1 cylinders.


Which means that at least you need 4 cylinders to generate a force at least of 775 lb-f.

A 0.080-kg egg test dummy is fitted with a helmet and attached to a swing. This egg test dummy is pulled back and released, allo
BabaBlast [244]

Answer:

7.8 N

Explanation:

Applying,

I = Ft................. Eqaution 1

Where I = Impulse on the egg test dummy, F = Force on the egg test dummy during the time interval, t = time interval

make F the subject of the equation

F = I/t.................. Equation 2

From the question,

Given: T = -0.39 N.s, t = 0.050 s

Substitute these vales into equation 2

F = -0.39/0.050

F = -7.8 N

Hence the force that act on the egg test dummy is 7.8 N
