How can you determine the specific heat of a metal using a calorimeter? Place the metal piece into the water of the calorimeter and measure the highest temperature reached by the water. This is the final temperature of both the metal and the water. The energy change of water is calculated by rearranging the specific […]
When the angle between surface tension with the liquid θ is greater than 90 degree the liquid becomes?
When the angle between surface tension with the liquid θ is greater than 90 degree the liquid becomes? If θ is obtuse, i.e; θ >90°, then liquid meniscus will be convex upwards. If angle of contact is acute angle, i.e; θ <90°, then liquid will wet the surface. When there is a capillary depression What […]
How do you test a 3 phase motor with a Megger?
How do you test a 3 phase motor with a Megger? Turn off the power supply to the motor, usually accomplished by switching the circuit breaker. Place one megger probe to the any mounting bolt on the breaker box to test for grounding continuity, then touch the other probe to a motor terminal. Crank the […]
How do you find the critical buckling load?
What is calibration error?
What is calibration error? The difference between values indicated by an instrument and those that are actual. Normally, a correction card is placed next to the instrument indicating the instrument error. Also called calibration error. What are the four types of errors? Errors are normally classified in three categories: systematic errors, random errors, and blunders. […]
What is physical education class?
What is physical education class? Physical education, also known as gym class, is a class taught in kindergarten through 12th grade that involves student participation in physical activity. The goal of physical education classes is to introduce students to the basic elements of exercise that will lead to a healthy lifestyle. What are the 4 […]

When your car travels rapidly over a bump in the road you suddenly feel weightless explain?
When your car travels rapidly over a bump in the road you suddenly feel weightless explain? When your car travels rapidly over a bump in the road, you suddenly feel weightless. Explain. You lose contact with your seat, so your apparent weight becomes zero. Astronauts learn to tolerate weightlessness by riding in an airplane (nicknamed […]
What is the total resistance of two resistors in parallel?
What is the purpose of circuit analysis?
What is the purpose of circuit analysis? The general strategy of circuit analysis is to create and solve a system of independent equations. Written by Willy McAllister. Circuit analysis, or solving a circuit, means figuring out voltages and currents in each element. Which basic laws should be followed to Analyse the circuit? What is the […]
