EXPERIMENT NO-1 AIM- To determine the frequency of A. C. mains by using an electric vibrator. APPARATUS- Electric vibrator‚ table lamp‚ pulley‚ weight box‚ fishing cord‚ a. c. source. THEORY- when a cord of mass per unit length m is connected to the vibrating rod of the vibrator and stretched with a tension T‚ the cord vibrators in segments. If the length of the cord is then adjusted until the nodes are clearly marked‚ the frequency of the stretched string is the same as of the vibrating rod which

too high‚ the feedback mechanism quickly reacts and makes the body sweat. The feedback mechanism contains receptors that sense the stimulus which goes to its rightful control system and the effectors react to the response. In "Human Physiology with Vernier"‚ it explains how heart rate responds to the baroreceptors feedback. As the leg muscles become compressed‚ it causes a sudden increase in stroke volume (amount of blood pumped with each beat)‚ and pressure which are sensed by the baroreceptors. 2

environmental temperature decreased‚ the respiration rate of mice would increase. I predicted that if environmental temperature decreased‚ the respiration rate of mice would increase. The respiration rate of the endotherm was measured using the Qubit/Vernier system and the S152 CO2 gas sensor‚ a device that measured the CO2 concentration in the air. The independent variable for both the control and experimental treatment was temperature. In the control treatment‚ the independent variable was room temperature

of cockles in different intertidal locations could be compared. This was achieved by firstly‚ measuring the length of each cockle from the three intertidal positions (high‚ mid‚ low) from the anterior to the posterior of the cockle using a pair of calipers. This length was recorded on an Excel spreadsheet in millimetres (mm). Each cockle was also placed under a dissecting microscope where it’s winter rings were counted to determine the cockle’s ages (years) if no rings were present the cockle’s age

Worn-out brake pads‚ leaking brake fluid and defective calipers and hoses are the most common Breaking system problems. These parts need to be regularly checked and if the problem is detected‚ it should be fixed immediately. There are brake problem signs you need to know You do not have to wait until an inspection
