What is the difference between time and clock? If a grandfather clock were running slow, how could we adjust the length of the pendulum to correct the time? Find a clock or watch with hands and estimate the possible parallax error of the minute hand. Describe what you did and your results...
英文的意思是：根据人类的反应时间从开始到结束，时间间隔的测量用秒表通常有约0.2的不确定性 。如果要计算的话，你可以设定一个开始的时间和结束的时间， 实际的结束时间要考虑0.2秒的不确定性。我认为应该考虑两种情况：多0.2或少0.2秒。

In order to measure a quantity, the quantity must be compared with a standard quantity and accordingly the measurement can be made and least count plays a very significant role in the measurement as it decides the minimum value of quantity that can be measured by the instrument....
Will G Hopkins Sport and Recreation AUT University Auckland NZ What is Research? How to do Research: solve a problem, publish Dissecting the Dimensions of Research: topic, novelty, technology, scope, mode, methods, ideology, politics, utility Reassembling the Dimensions: quantitative vs qualitative ...
If you are looking to start a new one, here are some thoughts contrasts with the animal world and the whole dating process laid out simply. We have been in and out of lockdown and uncertainty for the last 16 months. Fear and frustration have been building up and dating has been difficul...
Some parties (think of a city government for example) need predictable budgets and can’t stand price uncertainty. They can make contact with other people who are willing to take on risk in exchange for a fixed fee. Financiers call these fixed-for-float swaps. For wholesale grid energy, the...
1 What is a TTL signal? Discrete inputs are normally output from a relay or transducer at TTL (transistor to transistor logic) levels, which are based on a 5V pull-up. In theory, the perfect TTL on/off signal would be 0V representing OFF (meaning a digital value of 0), and 5V ...
When taking a simple moment experiment using hi-tech apparatus, hangers, weights stirrups, what are the source of errors during the experiment? What is the test for whether or not a moving object is in equilibrium? What is the uncertainty of a physics lab? What does unce...
What is the formula for the range of error? When looking for the ratio of circumference to diameter which variable has a bigger contribution in the uncertainty and why? Consider the following function of variable r, for r > 0: y(r) = (r^2 ...
