Does it matter what type of media a wave travels through? The Medium The energy of a mechanical wave can travel only through matter. The matter through which the wave travels is called the medium (plural, media). The medium in the water wave pictured above is water, a liquid. But the medium of a mechanical […]
What are the responsibilities of the Nuclear Regulatory Commission?
What are the responsibilities of the Nuclear Regulatory Commission? The NRC licenses and regulates the Nation’s civilian use of radioactive materials to provide reasonable assurance of adequate protection of public health and safety and to promote the common defense and security and to protect the environment. Is NRC under DOE? The NRC, consistent with its […]
What is Sopite syndrome?
What is Sopite syndrome? Sopite syndrome, which is a constellation of symptoms that involves apathy, depression, disinclination for work, and decreased participation in group activities, can occur. These and other neurophysiologic symptoms such as maliase, lethargy and agitation can persist for some time after the motion stimuli has ended. Why is my motion sickness not […]
What are the three main forms of arteriosclerosis?
What are the three main forms of arteriosclerosis? There are three recognized types of arteriosclerosis: atherosclerosis, arteriolosclerosis, and Monckeberg medial calcific sclerosis. What are symptoms of hardening of the arteries? If you have atherosclerosis in the arteries in your arms and legs, you may have signs or symptoms of peripheral artery disease, such as leg […]
What causes the density of a balloon to decrease?
What causes the density of a balloon to decrease? The stronger outside air pressure compresses the balloon. As the balloon volume decreases, pressure inside the balloon increases. It eventually is able to balance the outside air pressure. If you warm a parcel of air the volume will increase and the density will decrease. Can you […]
What is the relation between pressure and flow rate?
What is the relation between pressure and flow rate? Fluid velocity will change if the internal flow area changes. For example, if the pipe size is reduced, the velocity will increase and act to decrease the static pressure. If the flow area increases through an expansion or diffuser, the velocity will decrease and result in […]
Where is quantum tunneling used?
Where is quantum tunneling used? Quantum tunneling plays an essential role in physical phenomena, such as nuclear fusion. It has applications in the tunnel diode, quantum computing, and in the scanning tunneling microscope. Is a quantum computer faster? That suggests the quantum computer can do GBS 100 trillion times faster than a classical supercomputer. This […]
Can sulfur form ionic bonds?
Can sulfur form ionic bonds? Sulfur, which only needs two electrons to complete it octet, will pick up the two electrons coming from magnesium, becoming the sulfide anion, S2− , in the process. The electrostatic force of attraction will then bring the magnesium cations and the sulfur anions together → an ionic bond is formed. […]
What best describes the physical and chemical digestion of food?
What best describes the physical and chemical digestion of food? Which best describes the physical and chemical digestion of food? Physical and chemicall digestion occur in the small intestine; only chemical digestion occurs in the mouth. Only physical digestion occurs in the stomach; chemical and physical digestion occur in the large intestine. Where does chemical […]
Why is U-235 good for chains?
Why is U-235 good for chains? A critical chain reaction can be achieved at low concentrations of U-235 if the neutrons from fission are moderated to lower their speed, since the probability for fission with slow neutrons is greater. Can I own a nuclear weapon? Originally Answered: Is there any specific law outlawing private nuclear […]
