How do you calculate J value? To calculate J for a duplet, simply subtract the lower value from the higher. If the second peak results in a value of 502.68, for example, the value for J would be 2.02 Hz. The peaks within a triplet or quadruplet all have the same spacing, so you’ll only […]
What should oxygen and acetylene be set at?
What should oxygen and acetylene be set at? In case the recommended working pressure settings are not indicated, safe numbers are 40 psi for oxygen and 10 psi for acetylene, regardless of cutting tip size. Simply adjust them until you get a neutral flame, but pay close attention to the acetylene pressure to prevent it […]
Is energy released in alpha decay?
Is energy released in alpha decay? The energy released in this α decay is in the MeV range, about 106 times as great as typical chemical reaction energies, consistent with many previous discussions. Most of this energy becomes kinetic energy of the α particle (or 4He nucleus), which moves away at high speed. Is energy […]
What is destructive criticism example?
What is destructive criticism example? Examples of destructive criticism are: “You’re wrong.” “You don’t look good in that dress.” It’s important to tell the criticism to yourself first and see how you’d take it before you say it. How do you know if criticism is constructive? If the criticism is truly constructive, it will be […]
What are the two main barriers against implementing a renewable energy system?
What are the two main barriers against implementing a renewable energy system? The Siting and Transmission However, they can still present two primary barriers to renewables namely siting and transmission. What are the barriers in implementing alternative fuels? Alternative Fuel Vehicles Are Expensive. New technologies almost always require a high level of front-end capital investment. […]
What is the best frequency for a tuning fork?
How can we protect the cryosphere?
How can we protect the cryosphere? By quickly taking steps to curb emissions from cookstoves, forest burning, fossil fuel extraction and diesel transport countries could help preserve the cryosphere while at same time saving the lives and health of millions. What would happen if the cryosphere melted? Unsurprisingly, water from the current cryosphere melt is […]
How does angle affect work?
What characteristics are used to identify metamorphic rocks?
What characteristics are used to identify metamorphic rocks? Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture. What is the classification of igneous rocks based on quizlet? […]
What happens when something reaches absolute zero?
What happens when something reaches absolute zero? At zero kelvin (minus 273 degrees Celsius) the particles stop moving and all disorder disappears. Thus, nothing can be colder than absolute zero on the Kelvin scale. Physicists have now created an atomic gas in the laboratory that nonetheless has negative Kelvin values. What determines the state of […]
