Experiment 3: Oscillators and timers Introduction The NE555 chip which operates at 5v‚ utilizes two comparators for temperature stability. This chip is capable of producing oscillations. It is made up of 8 pins and its oscillation mode is controlled by two resistors and a capacitor. Each pin is set to perform a function. Pin 1 serves as ground. Pin 2 is the trigger - the input to the lower comparator which sets the latch that causes output to go high. Pin 3 serves as the output.

Uniform Acceleration Cedric C. Labasan Physics Department‚ De La Salle University St. Joseph Hall Room 404‚ 2401‚ Taft Avenue‚ Manila‚ Philippines cedric_labasan@dlsu.ph Abstract This lab report defines what uniform acceleration is and how to calculate uniform acceleration of a cart rolling down a ramp at different angles and elevations. The experiment will be performed by setting the cart on the track against the end stop and then record this final position on the steel ramp ten times

THE FORCE OF GRAVITY Topics covered in this lab: Gravitational force Newton’s Laws One of the topics we have discussed is acceleration‚ meaning that the velocity of the object being studied is changing. What causes something to accelerate? In this lab you will investigate the forces that affect the motion of objects. Materials Something to toss Procedure Toss an object straight up into the air and catch it as it falls back down. Carefully watch the object’s vertical position

After a year of waiting‚ Diwali arrived. Everyone’s house would be lighted up with lamps & joy. Almost everyone loves celebrating Diwali. Though I’m an atheist‚ I also like this festival as it lights up the world. But along with bit happiness for the arrival of Diwali‚ I get lots of worry every year. Whatever you say‚ Diwali‚ along with bunch of other festivals & functions‚ are tagged with some key words – crackers‚ pollutions‚ global warming & noise. However we celebrate this Diwali; we can’t remove

Open-ended Investigation (mass and force) Aim: To show the relationship between Mass‚ the force acting on it‚ and acceleration by gathering data through investigations. Hypothesis: As Mass increases‚ Acceleration Decreases. Therefore‚ Acceleration is inversely proportional to mass. Introduction A force is a push or pull acting upon an object‚ as a result of its interaction with another object. In a state of motion‚ an object experiences different forces which influences its movement. There are many

Bio 114 1- Incisions in your Explain the purpose of the pig as illustrated in figure 4. In the figure fourth is the fetal pig incisions. The picture show many different part in the pig that we need to know to really understand what we going to do before starting doing our experiment .We need to know each part where there are and their functions so when we start open our pigs that we do not mess it at all. 2-How are the two sexes distinguished by external anatomy?
