Choose either eclipses or lunar phases and make a model of the event. Your model can take any form, providing it can explain how

your event takes place. Once you have created your model, use it to teach someone else about lunar phases or eclipses. Submit a picture, video, or diagram of your model to your instructor, along with evidence of how you used your model to explain your selected event.
Activity Checklist
Include a picture, video, or diagram of your model of lunar phases or eclipses.
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.
Include the name of the person you taught about your event and that person's description of what they learned from your model.

Answer: See the explanation below.

Explanation: For this assignment, I chose to display how eclipses are created.

My model was made utilizing a 3D displaying device program for all intents and purposes. The items utilized are three models I made for this presentation, Earth, the moon, and the sun. These three models will be utilized for the showcase.  

The light that shines from the sun would create a shadow on the moon. The moon would then catch the light that should've arrived on Earth, making the shadow we call an eclipse. Earth gets a shadow of the moon and the remainder of Earth is lit up from the rest of the light, making an eclipse.  

The individual I demonstrated my project to was [<em>Someone you know</em>], [<em>Pronoun</em>] said it precisely took after the occasion of an eclipse. The light from the sun being shined on to the moon rather than the Earth, creating the shadow we call an eclipse.

If a person is walking along at 1.4m/s. How long will it take that person to walk one time around a high school track?​
ratelena [41]

Answer:

285.7s

Explanation:

Given parameters:

Speed of the person  = 1.4m/s

Unknown:

Time it takes to walk one time round the track = ?

Solution:

The circumference of the track is 400m for a standard pitch.

Now;

 Speed  = \frac{distance}{time}

 Time  = \frac{distance }{speed }  

 Now insert the parameters;

Time  = \frac{400}{1.4}  = 285.7s

A mysterious rocket-propelled object of mass 49.5 kg is initially at rest in the middle of the horizontal, frictionless surface
Romashka-Z-Leto [24]

The distance covered by the rocket in the first 5 seconds is 7.13 m

Explanation:

In order to solve the problem, we have to find the acceleration of the rocket. We can do it by using Newton's second law, which states that the net force on the rocket is equal to the product between its mass (m) and its acceleration (a):

F(t)=ma(t)

Where here we have:

F(t)=16.8t is the time-dependent force

m = 49.5 kg is the mass

Solving for a(t),

a(t)=\frac{F(t)}{m}=\frac{16.8t}{49.5}=0.34t[m/s^2]

This is the time-dependent acceleration of the rocket.

By integrating this expression, we  find the velocity of the rocket at time t:

v(t)=\int a(t)dt=\int (0.34t)dt=\frac{0.34t^2}{2}=0.17t^2

where we didn't add the constant term since the velocity at t = 0 is zero (the rocket starts from rest).

By integrating this expression, we then find an expression for the position of the rocket at time t:

x(t)=\int v(t) dt = \int (0.17t^2)dt=\frac{0.17t^3}{3}=0.057t^3

Therefore, the distance covered by the rocket in the first t = 5.00 s is:

x(5)=0.057(5.0)^3=7.13 m

In each cycle, a heat engine receives an input of 1540 J of heat and exhausts 1030 J of heat. What is the thermal efficiency?
Katarina [22]

The thermal efficiency of a combustion system is simply the ratio of heat out and heat in, that is:

efficiency = heat out / heat in

efficiency = 1030 J / 1540 J

efficiency = 0.669

 

<span>So the efficiency is 0.669</span>
