A population of 50 mice was introduced into a field where there haven't been any mice before. Even though they had to deal with predators, the population grew at 2% per month.

1. Create an exponential model where p in the population of mice and m is the number of months that have passed since the initial population was introduced.

2. How many months does your model say it will take the population to reach 100? How about 200? Fill in the blanks and explain how you did it

It will take ________ months from the initial introduction for the population to reach 100, and _______ months from the initial introduction for the population to reach 200.

3. The "rule of 70" says that if a number grows at p% per time period, it will take about 70/p time periods to double. For example, a population that grows at 1% per year should take about 70/1=70 years to double. Explain how your work in the previous problem shows that this "rule" was followed by the mouse population.

Look up “Doogie mice” on the Web. These mice have been genetically altered so that they express a particular gene that plays an important role in memory. As a result, the mice remember better, and therefore seem smarter. What is your impression of the “Doogie mice?” Could this hold the answer for creating smarter humans? Is this something that warrants further study, in other animals or eventually humans? Answer must be 2 to 3 paragraphs.

The pupil of an eagle’s eye has a diameter of 6.0 mm. Two field mice are separated by 0.010 m. From a distance of 199 m, the eagle sees them as one unresolved object and dives toward them at a speed of 18 m/s. Assume that the eagle’s eye detects light that has a wavelength of 550 nm in vacuum. How much time passes until the eagle sees the mice as separate objects?

We are introduced to the magnetic field as a way to keep track of the force that arises from lenght contraction in special relativity. A moving distribution of charge becomes more dense in the right frame. So in a way, the magnetic field is just the E-field. However, when I glance over the physics of permanent magnets, it is said that their magnetic field arises from the integral sum of their electrons with aligned spin(which generates a magnetic moment).Spin is...
