Does velocity increase with mass? The mass of an object does not change with speed; it changes only if we cut off or add a piece to the object. Can momentum be lost? That is, the momentum lost by object 1 is equal to the momentum gained by object 2. In most collisions between two […]

How does low pressure affect the body? Lower air pressure pushes less against the body, allowing tissues to expand. Expanded tissues can put pressure on joints and cause pain. What weather is low pressure associated with? Low-pressure systems are associated with clouds and precipitation that minimize temperature changes throughout the day, whereas high-pressure systems normally […]

How do you solve a spring pulley problem? Hint: To solve this type of problems, the first step is to find the mean position of the spring mass system i.e. the natural length of the spring is the position of equilibrium point. Second step is to displace the object from its mean position, the restoring […]

Can permafrost melting be reversed? The cold air stops the permafrost from thawing. Another way to stop damage from thawing permafrost is to thaw the ground first. This method makes the ground more stable to build on. Then there is no danger of the ground beneath the new structure refreezing, because the structure keeps the […]

How can I improve my health behavior? How Healthy Behaviors Support Mental Health Getting proper exercise. Eating nutritious foods. Practicing good sleep hygiene. Socializing with supportive friends and family. Taking medications as prescribed. Practicing mindfulness or meditation. Talking about your emotions. How do you modify behavior? Behavior modification relies on the following: Reinforcement (positive and […]

Are human involved in triggering natural disasters? So there’s little doubt that humans influence natural disasters over the long term. But can we also trigger sudden “natural” catastrophes? The answer is yes. From mud volcanoes to disappearing lakes, human actions can have all sorts of unforeseen environmental consequences. What are the effects of natural disaster […]

What does the law of inertia state? Law of inertia, also called Newton’s first law, postulate in physics that, if a body is at rest or moving at a constant speed in a straight line, it will remain at rest or keep moving in a straight line at constant speed unless it is acted upon […]

How is the shielding effect related to atomic radius? Shielding is when electrons in the inner electron shells of an atom can shield the outer electrons from the pull of the nucleus. The nucleus can pull the outer electrons in tighter when the attraction is strong and less tight when the attraction is weakened. This […]

What is the induced current in the loop? A current can be induced in a conducting loop if it is exposed to a changing magnetic field. In other words, if the applied magnetic field is increasing, the current in the wire will flow in such a way that the magnetic field that it generates around […]

What is tissue and function? Tissue is a group of cells that have similar structure and that function together as a unit. Primary types of body tissues include epithelial, connective, muscular, and nervous tissues. Epithelial tissues form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in […]
