What is carbon 14 used to date? Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon, a radioactive isotope of carbon. What is the lifespan of carbon 14? Carbon-14 has a half-life of 5,730 […]
What are the three elements of any project?
What are the three elements of any project? The triple constraint theory, also called the Iron Triangle in project management, defines the three elements (and their variations) as follows: Scope, time, budget. Scope, schedule, cost. Good, fast, cheap. What a project is not? Things that we do (or work that we do) which is routine […]
How do you maintain a triple beam balance?
How do you maintain a triple beam balance? Maintenance: Keep the triple beam balance clean at all times to maximize longevity. Most debris is easily moved using a can of compressed air. Never apply lubricants to the knives or bearings. Why is it important to zero your balance before you mass something? The mass of […]

Why is gravity weaker underwater?
Why is gravity weaker underwater? This is because water exerts a kind of frictional force called “force of buoyancy”. When you throw something into water , the water below the object will push it upwards making the object weigh less. Why is there no gravity under water? There is gravity everywhere. Gravity is just the […]
