What is the maximum potential energy of the spring? When the kinetic energy is maximum, the potential energy is zero. This occurs when the velocity is maximum and the mass is at the equilibrium position. The potential energy is maximum when the speed is zero. What is the potential energy of a spring derive it? […]
How do you turn on a blind intersection?
How do you turn on a blind intersection? What should you do in a Blind Intersection? In such a scenario, you should inch forward slowly until you can see clearly to cross the intersection. Once clear, you can continue as normal. However, by crossing slowly, you can quickly stop if another car comes into the […]
What element has 2 protons 2 neutrons?
What element has 2 protons 2 neutrons? Helium What did Chadwick prove? In 1932, Chadwick made a fundamental discovery in the domain of nuclear science: he proved the existence of neutrons – elementary particles devoid of any electrical charge. For this epoch-making discovery he was awarded the Hughes Medal of the Royal Society in 1932, […]
Is burning of candle a reversible change?
Is burning of candle a reversible change? When a candle is burned, chemical reactions take place between the wax and oxygen. These chemical reactions release energy in the form of heat and light. These chemical reactions can’t be reversed back. What ways to change the materials? What are some ways of changing solid materials? Physical […]
Can COVID-19 affect a newborn baby?
Can COVID-19 affect a newborn baby? COVID-19 is uncommon in newborns born to mothers who had COVID-19 during pregnancy. Some newborns have tested positive for COVID-19 shortly after birth. It is unknown if these newborns got the virus before, during, or after birth. Most newborns who tested positive for COVID-19 had mild or no symptoms […]
What are the two main functions of cell wall?
What are the two main functions of cell wall? The main function of the cell wall is to provide structural strength and support, and also provide a semi-permeable surface for molecules to pass in and out of the cell. Where are cell walls found? A cell wall is a fairly rigid layer surrounding a cell […]
What is the difference between stored energy and usable energy?
What is the difference between stored energy and usable energy? The stored energy is termed as potential energy while the working energy is termed as kinetic energy. The electricity used in our homes is also a form of energy because it is a form of usable power. The places from which the different energies are […]
How much force does a falling person have?
How much force does a falling person have? OSHA limits the amount of force that a person should experience during a fall to 1,800 pounds. Forces greater than this can result in internal bleeding, damage, or death. When a personal fall arrest system is used, a shock-absorbing lanyard or fall limiter is the only way […]
What are three types of models?
What are three types of models? Contemporary scientific practice employs at least three major categories of models: concrete models, mathematical models, and computational models. What is simple model? A Simple Model exists to make the skill set required to build financial models more accessible. The intention is to create simple material and facilitate the learning […]
What is the 5 step design process?
What is the 5 step design process? The five stages of Design Thinking, according to d. school, are as follows: Empathise, Define (the problem), Ideate, Prototype, and Test. Let’s take a closer look at the five different stages of Design Thinking. What is the difference between scientific investigation and technological design? Scientific inquiry is used […]
