Interstellar is a movie about the human race being faced with a
civilization ending blight. A small group of brave individuals explore
possible new habitable worlds for humans. The following questions
will help guide you through the movie and hopefully get you
thinking about the future.
1. The Cooper family hijacks a UAV (Unmanned Aerial Vehicle).
What do you know about UAVs and how they are used today?
2. While at the parent-teacher conference, Murphy’s teacher
mentions that the Apollo program -- the same program that
landed humans on the Moon -- was just propaganda to
convince the Soviet Union to bankrupt themselves trying to do
the same. The reason for this was to encourage children to
take care of their own planet, rather than wasting precious
resources day dreaming of leaving it. Which side of the fence
would you sit on? Would you look for ways to save Earth and
our ability to stay there, or would you look to the sky, and find
a new planet to live on? Why?
3. A) What natural disaster(s) is Earth suffering from in the beginning of Interstellar?
B) If one of these happened now what actions would you take to protect yourself?
4. Cooper, Doyle, Romilly, and Dr. Brand (female) rendezvous with the Endurance in orbit around Earth. Once
onboard, they begin to spin the Endurance. Why? (Think about the physics happening here!) Draw a diagram.
5. Why or why isn’t space exploration important for the people in the movie interstellar? Why or why isn’t
space exploration important in today’s society? Defend your answers.
6. Explain time dilation as best as you can.
7. A) Estimate how long Dr. Mann went without human contact while on the ice planet:
The Lazarus mission was __________ years ago. It takes _______ years to get to Saturn from Earth. Cooper
and Dr. Brand were on Miller’s planet for approximately __________ years. This means the total time Dr.
Mann went without human contact is: ___________ years.
B) Consider the longest time away from human contact you've experienced. What did you do to keep yourself
occupied?

If there were no external forces acting on the two pucks, their complex motion could be described as the combination of the uniform linear motion of the center of mass and a uniform circular motion of the pucks about the center of mass. Describe how well your results agree with this expectation, and explain any deviations that you observe from the predicted behavior
The absence of external forces will make the pucks move in the form of a uniform circular motion.
What is a circular motion?It should be noted that a circular motion simply means the movement of an object along the circumference of the circle.
In this case, the absence of external forces will make the pucks move in the form of a uniform circular motion.
If the friction is absent, the pucks will continue to move on the same path due to the first law of Newton and the law of conversation of energy. In this case,the results will match the predictions until there's loss in energy.

Hope this helpsThe three fundamental colors of visible light are red, green and blue. Why does a yellow T-shirt appear yellow to you
This one is leisure for people with common sense. Yellow is an assortment of two of the rudimentary colors, red and green. Yellow appears yellow because red light is being imaged in our eyes, so that's one thing. Green reflections are capable of being enthralled by the shirt; hopefully, this should be meticulous adequate for you to have a basic understanding of this "phenomenon". Cheers!
A yellow T-shirt appear yellow to human eye because it reflects both red and green lights and our eye detects it as a combination of two fundamental colors (red and green), which is yellow.
What is color?Color is a perception. Our eyes sense something (the sky, for instance), and information is transferred from our eyes to our brains informing us that it is a particular color (blue). Different combinations of wavelengths of light are reflected by objects. When our brains detect certain wavelength combinations, they transform them into the phenomena known as color.
There has three fundamental color: red, blue and green. Red and green lights are combined to create yellow light. If a shirt reflects both red and green light, it appears yellow to human eyes. These two fundamental colors of light must be present in the incident light for red and green light to reflect yellow light to human mind.

Subtract the greatest value of the angular speed from the smallest value of the angular speed, because α=Δω.
Subtract the greatest value of the angular speed from the smallest value of the angular speed, because a equals delta omega .
Determine the slope of the line from 0s to 2s, because the slope represents ΔωΔt.
Determine the slope of the line from 0 second to 2 seconds , because the slope represents the fraction delta omega over delta t .
Determine the area bounded by the line and the horizontal axis from 0s to 2s, because α=12ωΔt.
Determine the area bounded by the line and the horizontal axis from 0 second to 2 seconds , because alpha equals one half omega delta t .
The angular acceleration cannot be determined without knowing the rotational inertia of the object.
We can find it up angular velocity with respect to time graph .
As
[tex]\\ \rm\Rrightarrow m=\dfrac{\Delta \omega}{\delta T}[/tex]
[tex]\\ \rm\Rrightarrow \alpha=\dfrac{\Delta \omega}{\delta T}[/tex]

We can determine the angular acceleration of the object by taking the slope of the line in the plot of angular speed versus time because the change in linear here.
What is angular acceleration ?The angular acceleration of an object is the measure of its rate of change in angular speed. Like the velocity, it a vector quantity and is characterized by a magnitude and direction.
The acceleration is the ratio of change in velocity to the time interval. From the graph of speed of an object versus the time taken, we can obtain the acceleration.
For a linear relation between the two quantities, the slope gives their ratio. Therefore, here, the slop of the line from 0 to 2 seconds represents the fraction delta omega over delta t. Hence, option D is correct.
