bob moves‚ as shown in Figure 1‚ will determine the initial velocity‚ V‚ of the bob after it receives the moving ball. If we equate the kinetic energy (KE) of the bob and the ball at the bottom of the potential energy (PE) of the bob and ball at the height‚ h‚ that they are raised to‚ we get: KEbottom = PE top ½ (M + m) V2 = (M + m) g * h where M is the mass of the pendulum and m is the mass of the ball. Solving for V we get: V = √2gh .......... (1) Using conservation of momentum

to collect the data from the experiment‚ and then taking our data and presenting it and our results in a report. Method: For this experiment‚ the goal was to use a simple pendulum (shown to the left) to measure the period of the motion. For task 1‚ we just became familiar with DataStudio and learned how to use it to time each “swing” of the ball on the end of the pendulum. Then‚ in task 2‚ using the materials provided we decided that the variables that would have effect on the period are

and causeways to allow vehicles to surmount vertical obstacles such as hills without losing traction on the road surface. Similarly‚ pedestrian paths and sidewalks have gentle ramps to limit their slope‚ to ensure that pedestrians can keep traction.[1][4] Inclined planes are also used as entertainment for people to slide down in a controlled way‚ in playground slides‚ water slides‚ ski slopes and skateboard parks.

Your paragraph will discuss all the questions below in depth. Procedure and Data: 1. Tie the two pieces of string to the scales. 2. Hang a 1.00kg mass from the center of the string and move the clamps together such that the total angle between the two strings is about 15 degrees (half angle = 7.50). 3. Use the protractor to measure

TUBERCULOSIS Tuberculosis‚ commonly known as TB‚ is a contagious and an often severe airborne disease caused by a bacterial infection. TB typically affects the lungs‚ but it also may affect any other organ of the body. It is usually treated with a regimen of drugs taken for 6 months to 2 years‚ depending on the type of infection Tuberculosis was popularly known as consumption for a long time. Scientists know it as an infection caused by M. tuberculosis. In 1882‚ the microbiologist Robert Koch discovered
