Different measurement of quantities require different instruments. The way of measuring length is in deed quite different from the way to measure mass of an object or time taken for an event occur or that happened. This means that we can not use a thread or rope to measure weight of an object but we rather use it to measure width or length of a room. In this you are going to read and see about which instruments required to measure certain quantities. This article also will be restricted to some fundamental quantities such as length, mass and time. 1. Length Length is a measure of the gap or interval between two points. There are different instruments especially nowadays to measure length of an object, in which the choice of one to use depends on how longer the object is or how is it between the points that you wanted to measure. Below are some of the instruments we use to measure length. a) The Meter rule b) The vernier callipers c) The micrometer screw gauge d) The t...
When ever we made some measurements in our daily lives, we need to specify the difference between one and other measurements. This measurements can be a count(for money) or measurements for length, width(breadth), height, weight, mass, time, temperature(hotness or coldness of a body), speed(of a moving object), e.t.c. After all these measurements we get back a number(s)(which can be either whole, fraction or decimal) which when these numbers are presented without any indication (of which one measure either mass, temperature, time, e.t.c) one can never distinguish. Thanks to the units of measurements that give us the freedom to write our measurements attached with some unit or its symbol to indicate whether the measured value is for either length, mass or time. Before we dip in to units of measurements, we have to know that these units we wanted to know are for measured quantities. As we mentioned above, length, mass, time, temperature are quantities and are all called fundamental ...
Pi is a trending digital money. Currently, pi is in the mining state - a state in which the company tries t ok measure the commitment of its visitors - where a user is expected to visit the app or site and click on the mining botton each day (once in 24 hours). Alot of people are using Pi Network now. Since there are people with thousands of pi in their account some even much more. Referral is what give a user more benefit in the system, by referring a new user to the network, you earn 1pi and also the new user gets 1pi also. The higher the number of referral contributes to the number of pi per hour - For example a person with 1 referral can earn 0.12pi/hr if the person he/she refer is active while a person with 11 active users from his/her referral can earn 0.74pi/hr, and so on. So each active user contributes to your earning. Pi as a currency is expected to be launched on December, 2021. By this time, alot have been prepared by the developers together with help of the users to help e...
