Low thermal expansion is a characteristic of which state of matter?

Suppose that during the Millikan oil drop experiment you measured the radius on an oil droplet of 6.13 × 10-6 m. Use the equation below to find the mass of the droplet.

Which of the items in the image is the alpha particle source?  

Given a terminal velocity of 1.25 × 10-5 m/s, calculate the radii of the three droplets with the data below using the equation below

During the oil drop experiment you measure the distance a droplet of oil travels over a given amount of time. You use that to calculate the terminal velocity. From that you find that the droplet has a radius of 7.78 × 10-7 m and a mass of 1.62 × 10-15 kg. Use the first equation below to find the volume and use the second equation to find the total charge (Qtot).

A female patient comes in with a brain injury in the hypothalamus. The injury causes decreased levels of GnRH secretion. What effects would you expect to see in your patient?
