What is multiple proportions explain with an example?
What is multiple proportions explain with an example? This example illustrates the law of multiple proportions: Whenever the same two elements form more than one compound, the different masses of one element that combine with the same mass of the other element are in the ratio of small whole numbers. Figure 1. Carbon can form […]

How much elastic potential energy is in a compressed spring?
How much elastic potential energy is in a compressed spring? The work done to stretch or compress the spring is stored in the spring as elastic potential energy. The elastic potential energy of a spring is one half the product of its spring constant multiplied by the square of its deformation. Is elastic potential energy […]
What are the six principles of the life span developmental approach?
What are the six principles of the life span developmental approach? Baltes’ lifespan perspective emphasizes that development is lifelong, multidimensional, multidirectional, plastic, contextual, and multidisciplinary. Think of ways your own development fits in with each of these concepts as you read about the terms in more detail. What are the 8 stages of Erikson’s theory? […]

In which direction is the directional derivative the largest?
In which direction is the directional derivative the largest? The directional derivative takes on its greatest positive value if theta=0. Hence, the direction of greatest increase of f is the same direction as the gradient vector. The directional derivative takes on its greatest negative value if theta=pi (or 180 degrees). Why do we need directional […]
Why do transmission lines use High Voltage?
Why do transmission lines use High Voltage? The primary reason that power is transmitted at high voltages is to increase efficiency. The lower current that accompanies high voltage transmission reduces resistance in the conductors as electricity flows along the cables. This means that thin, light-weight wires can be used in long-distance transmission. What happens to […]
