What is the first law of quantum mechanics? The theory allows particles to be created and destroyed and requires only the presence of suitable interactions carrying sufficient energy. Quantum field theory also stipulates that the interactions can extend over a distance only if there is a particle, or field quantum, to carry the force. What […]
What is meant by laws of motion?
When we touch a metal spoon it feels cold Why?
When we touch a metal spoon it feels cold Why? A: In general, metals feel colder or hotter to the touch than other materials at the same temperature because they’re good thermal conductors. This means they easily transfer heat to colder objects or absorb heat from warmer objects. How do you feel when you touch […]

What are the five uses of energy?
What are the five uses of energy? We divide our energy use among four economic sectors: residential, commercial, transportation, and industrial. Heating and cooling our homes, lighting office buildings, driving cars and moving freight, and manufacturing the products we rely on in our daily lives are all functions that require energy. What are 3 things […]
What is a part of an experiment not being tested?
What is a part of an experiment not being tested? Controls or Controlled Variables A part of the experiment that is not being tested and is used for comparison of the experimental results. A control group should be used when conducting an experiment. How do scientists test their hypothesis? Scientists (and other people) test hypotheses […]
How does ice hockey speed up friction?
How does ice hockey speed up friction? During the sharpening process, the surface area of the skates is reduced, thus reducing the amount of metal that is making contact with the ice. Reducing the surface area by sharpening your skates reduces friction and increases speed. This additional speed comes in handy when you propel yourself […]
What are fuses used in?
What are fuses used in? What is a Fuse? Fuses are sacrificial devices used to protect much more expensive electrical components from the damaging effects of overcurrent. They consist of a low-resistance metal or wire that is used to close a circuit. Are fuses still used? Over 100 years later, fuses are still used to […]
What are the colors that have high energy?
What are the colors that have high energy? The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy (Figure 3). Is red a higher […]
