It is considered an environmentally friendly source of energy because it comes directly from the Sun; it does not involve the burning of fossil […]
How do you prove 3d vectors are collinear?
How do you prove 3d vectors are collinear? Three points with position vectors a, b and c are collinear if and only if the vectors (a−b) and (a−c) are parallel. In other words, to prove collinearity, we would need to show (a−b)=k(a−c) for some constant k. What is an example of a collinear? Three or […]
What is the advantage of Graphs over tables?
What is the advantage of Graphs over tables? According to Stephen Few, graphs reveal more than a collection of individual values. Because of their visual nature, they show the overall shape of your data. This is when you should use graphs instead of tables: The message is contained in the shape of the values (e.g. […]
Why is it possible for a bird to sit on a high voltage wire?
Why is it possible for a bird to sit on a high voltage wire? Birds are able to sit on electrical power lines because the electrical current essentially ignores the bird’s presence and continues to travel through the wire instead of through the bird’s body. A bird’s body is not a good conductor of electricity. […]

He says “You cannot create a self-sustaining civilization if the ticket price is $10 billion per person.” He believes that the cost should be about $200,000; equivalent to the median price of […]
What will happen if you let an enzymatic reaction go too long?
What will happen if you let an enzymatic reaction go too long? The longer an enzyme is incubated with its substrate, the greater the amount of product that will be formed. As a result, the rate of formation of product slows down as the incubation proceeds, and if the incubation time is too long, then […]
Does Dyno tuning make a difference?
Does Dyno tuning make a difference? A dyno tune commonly provides for maximum power, better drivability, good fuel economy and a smoother ride. It increases the horse power of your vehicle and returns the vehicle to stock fuel economy. It also prevents or minimizes backfire. Dyno tuning can also save you from costly repairs in […]
Is centrifugal a real force?
Is centrifugal a real force? The centrifugal force is very real if you are in a rotating reference frame. However, the centrifugal force is an inertial force, meaning that it is caused by the motion of the frame of reference itself and not by any external force. What causes centripetal forces? Centripetal forces cause centripetal […]
