D) The Sun would revolve around the Earth. 8. In the geocentric model (the Earth at the center of the universe), which motion would occur? B) the Sun in circular orbits C) Earth in slightly elliptical orbits D) Earth in circular orbits 9.
Answer:
The correct answer is C
Explanation:
In this exercise you are asked to analyze the following situation: for a fixed observer, the two balloons are launched at the same time.
If the observer is mobile moving towards the positive side of axis ax we have several
possibilities when starting the movement
* the observer is to the left of the two balloons
* the observer is between the two balloons
* the observer is to the right of the two baloomls
The time it takes for the signal to arrive to know which ball goes first is
v = d / t
t = d / v
If the signal goes at the speed of light, the speed is a constant and the time will depend only on the distance, so we see that the trigger changes depending on the relative position between a given ball and the observer.
Consequently, it will be seen which comes out first, depending on the relative position with the observer.
The correct answer is C
Hey I hope this helps in any way.
As the front<span> moves through, cool, fair </span>weather<span> is likely to follow. Warm </span>front<span> Forms when a moist, warm air mass slides up and over a cold air mass. As the warm air mass rises, it condenses into a broad area of clouds. A warm </span>front<span> brings gentle rain or light snow, followed by warmer, milder </span>weather<span>.</span>
The kinetic energy of a moving object is given by
where m is the object's mass and v its velocity.
In our problem, the initial kinetic energy is:
while the final kinetic energy is:
So, the kinetic energy lost by Lucy and her bike is
