How should Hector correct his diagram? How should Hector correct his diagram? He should make the arrow for “Path” curve downward. What happens to the force when the mass of one object is doubled? If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the […]
What is the best exercise for improving balance?
What is the best exercise for improving balance? Or try walking in a line, heel to toe, for a short distance. You can also try tai chi — a form of movement training that may improve balance and stability and reduce the incidence of falls. If you have severe balance problems or an orthopedic condition, […]
What determines why some traits are favorable?
What determines why some traits are favorable? Favorable traits are traits that promote an organism’s success in a particular environment. In this way, the external forces of nature determine, or “select” which traits (or even which types of organisms) will continue to exist in a population. Do most parasites kill their hosts? In contrast to […]
What is the most important precaution to take in order to ensure you are rescued in an emergency?
How many years did it take to form the first galaxy?
What happens if an enzyme is altered?
What happens if an enzyme is altered? If the enzyme changes shape, the active site may no longer bind to the appropriate substrate and the rate of reaction will decrease. Dramatic changes to the temperature and pH will eventually cause enzymes to denature. How does an enzyme speed up a reaction? Enzymes are biological catalysts. […]
Can variable names start with a capital letter?
Can variable names start with a capital letter? Variable names always begin with a lowercase letter. If a name consists of multiple words, the first letter of all words except the first is capitalized, for example, endOfLineMarker , totalBill . Although legal, variable names never contain the underscore (unless they are constants) or the dollar […]
Is electric potential zero when electric field is zero?
Is electric potential zero when electric field is zero? If the electric field is zero, then the potential has no gradient i.e.: the potential is equal across space. But potential is always measured relative to a baseline, so it can therefore be considered as zero. Where is the electric potential zero? The electric potential from […]
What is C in binding energy?
What is C in binding energy? 12 C. This is the mass of the carbon atom, i.e. the mass of the nucleus plus the six electrons in the neutral carbon atom. Let’s calculate its binding energy. Why heavy nuclei are unstable? The presence of too many protons and neutrons in heavier nuclei will upset the […]
What is meant by static pressure?
What is meant by static pressure? : the force per unit area that is exerted by a fluid upon a surface at rest relative to the fluid. What is another name for static pressure? Static pressure in fluid statics The term (hydro)static pressure is sometimes used in fluid statics to refer to the pressure of […]
