He uniformly accelerates over the first 10.5 ft to his maximum speed, which is then maintained until he crosses first base.

Brightness and Luminosity 31 The brightness or flux intensity of a star at an observer's location may be determined by measuring the rate at which its light enters the aperture of an observing instrument (this is referred to as photometry). We will call this "" (with units [Energy/time/Area] or [Watts/Area]). Imagine a sphere of radius, d (labeled "p" in the figure below), equal to the star's distance from the observer's location, at which the star is at the center (see the figure below). ALL of the star's light passes through the surface area of this sphere but only a small fraction passes through the instrument aperture. The fraction of the star's rate of light energy emission measured by the instrument is…

In other words, if we know the amount of light that is absorbed, we can calculate the concentration of the sample. For a certain substance the concentration (in moles per litre) is found by using the formula: (-) Where the I, is the intensity of the incident light and I is the intensity of light that emerges. Find the concentration of the substance if the intensity I is 70% of Io.

Explain how parallax measurements can be used to determine distances to stars. Why can we not make accurate measurements of parallax beyond a certain distance? While a meter is the fundamental unit of length, most distances traveled by humans are measured in miles or kilometers. Why do you think this is?
