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 […]

Is 19 km/h wind strong?
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 […]
Could we survive on earth without the greenhouse effect quizlet?
Could we survive on earth without the greenhouse effect quizlet? What is the greenhouse effect? No we would not be able to survive because without these gases, the Earth would be too cold for humans, plants and other creatures to live. The two largest greenhouse gases are Co2 and methane which comes from fossil fuels […]
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 […]
