Is Poison Ivy the only plant with 3 leaves? Poison ivy will always have three leaflets at the end of a long stem. Virginia creeper actually has five leaves per stem, though younger plants may only show three. Poison ivy leaves are often waxy and shiny, but may appear dull, particularly after it rains. Are […]
Why pennies should stay?
Why pennies should stay? Proponents of keeping the penny in circulation say that its use avoids increased prices that will hurt low-income households the most, that pennies have a long lifespan and are more cost-efficient to manufacture than nickels, and that pennies are vital to several charities’ fundraising efforts. Should we keep the penny pros […]
Why are psychologists so important?
Why are psychologists so important? Overall, psychologists assess, diagnose, and treat the psychological problems and the behavioral dysfunctions resulting from, or related to physical and mental health. In addition, they play a major role in the promotion of healthy behavior, preventing diseases and improving patients’ quality of life. How do I start learning about psychology? […]
Why the penny should be abolished?
Why the penny should be abolished? Proponents of abolition say that eliminating pennies could save millions, because they cost more to produce than they are worth; that they are rarely used as a payment method anymore; and that they create disproportionately high handling costs for businesses. Why are pennies bad for the environment? Making pennies […]
How a pendulum transforms kinetic energy into potential energy?
How a pendulum transforms kinetic energy into potential energy? As the washer swings down, potential energy is transformed into kinetic energy. At the bottom of the swing all energy is kinetic energy. As the washer moves up, kinetic energy is transformed into potential energy. At its highest point in the arc of the swing, once […]
What determines how much total energy something has?
What determines how much total energy something has? The mass of the object and the speed of the object are variables that determine how much kinetic energy something has. Where does a pendulum have maximum potential energy and kinetic energy? The potential energy of an oscillating pendulum is maximum at its extreme positions. In this […]
What causes a pendulum to slow down?
What causes a pendulum to slow down? A pendulum is an object hung from a fixed point that swings back and forth under the action of gravity. The swing continues moving back and forth without any extra outside help until friction (between the air and the swing and between the chains and the attachment points) […]

Why should we get rid of the penny?
Why should we get rid of the penny? Many of the reasons for eliminating the penny apply to other coins as well. Inflation has destroyed the value of nickels and dimes as well as pennies. 20 We could easily get rid of pennies, nickels, and dimes and be no more inconvenienced than the average person […]
How does a pendulum demonstrate conservation of energy?
How does a pendulum demonstrate conservation of energy? When a pendulum swings, potential energy is transformed into kinetic energy, and then back again to potential energy as the speed and elevation of the pendulum vary during the motion. What is the energy conversion in simple pendulum? As a pendulum swings, its potential energy converts to […]
