Is 19 km/h wind strong? 10 to 19 km/h Weather wanes will move, leaves will rustle, and you’ll feel a breeze on your face. Situation normal. 20 to 29 km/h Strong enough to straighten flying flags and shake small tree branches. How much is 70 km in miles per hour? Convert 70 Kilometers per Hour […]
How can you speed up an exothermic reaction?
How can you speed up an exothermic reaction? Decrease the temperature in Exothermic reactions (Reactions that release energy, or become hot) Add a catalyst (A substance that reduces activation energy, speeding up the reaction) Increase the concentration of reactants. Increase the concentration of catalysts. Why is a match exothermic? – when Energy is released along […]
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 very first step in the proton-proton cycle?
What is the very first step in the proton-proton cycle? The first step in this process is the collision of two protons where proximity permits the strong nuclear force to bind them together. The resulting combination is not stable, and one of the protons will decay to become a neutron, and this forms a stable […]
Is it safe to swim to a sandbar?
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 […]
How do you determine instantaneous speed?
How do you determine instantaneous speed? Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time. The slope of a position-versus-time graph at a specific time gives instantaneous velocity at that time. What does instantaneous rest mean? It […]
What is the relationship between the earth and the moon?
How do I increase the resolution of my GC?
How do I increase the resolution of my GC? To improve the resolution of earlier eluting peaks, decrease the initial temperature or increase the initial hold time. Decreasing the initial temperature usually results in the largest resolution improvement, but analysis times are substantially increased (Figure 32a). What affects resolution in GC? Changes in resolution are […]
What is the smallest unbreakable unit of a compound?
What is the smallest unbreakable unit of a compound? molecule What are the similarities and differences of the two compounds? A compound contains atoms of different elements chemically combined together in a fixed ratio. An element is a pure chemical substance made of same type of atom. Compounds contain different elements in a fixed ratio […]
