quantity of rain falls close to the source of the river there will be a greater amount of water travelling down stream and as a result the volume of water will be travelling at a higher speed. In the section of the river harbourne that that this measurement was taken in a high river velocity can indicate that Harbertonford is susceptible to flooding‚ a hazard that the flood defences in place in the village are designed to deal with. In order to gain a figure of river velocity a count box and an impellor

It defines the measurements gathered‚ and characterizes the relationship of each value to each other. The experiment aimed to use statistical concepts in evaluating the gathered data‚ find the inevitable errors‚ and qualify the different parameters of the said data set. Ten

Paper cone Lab Variables: - Independent: The independent variable is the diameter of the paper cone’s base. - Dependant: The time will be measured to see how long does it take the paper cone to land on the floor. For this measurement we are going to use a stopwatch and the time measured is going to depend on our reaction time. - Controlled: The mass of the paper cone and also the height from which we are going to drop the paper cone are constant. The acceleration due to gravity will

exercise is to guess the angle as close to its true value as you can. After you have found your values you can use those values to calibrate the system. After calibration the system will read the incoming voltage and correlate that to an angle measurement. Exercise 4: Using the infrared sensor we are able to find how far away some thing is. We took readings at measured intervals and correlated those readings to the measured distances. Results: Exercise 1: This was a quick exercise. Take

Use the buttons 1. Remove the rubber caps from the test leads. SELECT — Toggles among functions. 2. Plug the black lead into the –COM jack and the red lead into the +V..mA jack. RANGE — Selects manual mode and ranges. REL — Takes relative measurements. To measure current greater than 400mA‚ plug the red test lead into +10A MAX. HOLD — Tests display and holds a reading. Note: The buzzer sounds after connecting to the +10A MAX jack to measure anything except current. This reminds you not to

The test was performed by creating a balance between three weights tied to strings on a pulley that transferred the string on top of a graduated disc‚ which made easy the measurement of the angles between them. After performing the experiment‚ my group concluded that there is a relation between the angle between the vectors and the magnitude of the resulting vector.
