Investigation into how the focal length of a lens affects the temperature at the focal point Research & Rationale: In my project I will be looking in to how different lenses with varying thicknesses and therefore focal points magnify and intensify light passing through it. To do this I will be measuring the temperature of an object behind the lens‚ at the focal point. The study and research of lenses was not part of the course this year‚ so I thought it would be more interesting to study a new

Arc Length The definition of radian measure s = rθ The unit circle An angle of 1 radian Proof of the theorem IT IS CONVENTIONAL to let the letter s symbolize the length of an arc‚ which is called arc length. We say in geometry that an arc "subtends" an angle θ; literally‚ "stretches under." Now the circumference of a circle is an arc length. And the ratio of the circumference to the diameter is the basis of radian measure. That ratio is the definition of π. π | = | C D | . |

The Lengths of Leadership This Freshman Seminar displayed the power of leadership in all of its forms. There are many types of leadership skills and characteristics; however‚ they all are encompassed by a set of core values one must follow to be a leader. We explored what could be called the ten commandments of leadership during class discussion and how they applied to a series of movies including Apollo 13‚ Courage Under Fire‚ Norma Rae‚ and Cry Freedom. In each movie‚ every character showed a

pendulum’s period‚ depends only on the pendulum’s length and the value of gravity. In an experiment‚ an experimenter can easily manipulate a pendulum’s length. The value of gravity cannot be manipulated. The best way to find the gravity of a planet/moon using a pendulum would be to use the pendulum to find the time it takes to swing the length of a period. So we know two variables in the equation g=4π2L/(T2)‚ where g is gravity‚ L is the length of the pendulum‚ and T is the period of the pendulum

PROJECT Introduction Title: Investigate one factor that affects the resistance of a wire. Reworded: I am going to investigate if changing the length of a wire changes its resistance. I predict that the longer the wire‚ the more resistance it has. Planning and Preparation Independent Variable: The variable I changed was length (cm). Dependent Variable: The variable I measured was resistance (Ω). Fixed Variables: The variables I kept constant to make it a fair test; were‚ the type of wire (nichrome)

An example of this for each theorem is: Example 1 Two Chords Intersecting Externally By using similar triangles the connection between chord lengths can be seen. Triangle ACE is similar to Triangle BDE (equal angles) Example 2 Two Chords Intersecting Internally By using similar triangles the connection between chord lengths can be seen. Example

BSMA 2C Table 1 shows the descriptive statistics about the 74 models of automobiles released in the year 1978‚ these include the automobiles’ price‚ mileage‚ repair record‚ headroom‚ trunk space‚ weight‚ length‚ turn circle‚ displacement and the gear ratio with its corresponding results. In terms of automobiles’ price‚ it ranges to $3‚291.00 up to $15‚906.00 for the period of the said year. Its average price is $6‚165.26 with a standard deviation of $2‚949.50. It can be seen
