Is it OK to use WD40 on bike chain? Can I use WD-40 to lube my bicycle chain? No. You should never use WD40 as chain lubricant since WD-40 is NOT a true lubricant since it’s primary use is as a solvent or rust dissolver. How often should I oil my bicycle chain? The recommendation […]
Is salinity higher in deep water?
Is salinity higher in deep water? Typically, the salinity decreases from the surface ocean to deep waters is very small, from about 36 g/L (ppt) at the surface to 35 g/L (ppt) in the deep water, thus there is a very small density decrease with depth given a constant temperature. The salinity of seawater also […]
Why is apparent weight less than true weight?
Why is apparent weight less than true weight? A floating or immersed object is not accelerating upwards or downwards, so there can be no net force. In fact, buoyancy provides a supporting force exactly as the ground does. Objects also experience some buoyancy in air, so even in air the normal force (apparent weight) is […]
What color lenses are good for night driving?
What color lenses are good for night driving? Night driving glasses are available in many shades of yellow and amber. The darkest lenses filter out the most glare but also, the largest amount of light, making it hard to see in dim or dark conditions. Some wearers of night driving glasses report that they’re better […]
How many watts does it take to boil water?
What factors determine whether a collision between two reactant molecules will result in a reaction quizlet?
What factors determine whether a collision between two reactant molecules will result in a reaction quizlet? 14.51. (a) What factors determine whether a collision between two molecules will lead to a chemical reaction? The energy of collision and the orientation of the molecules when they collide determine whether a reaction will occur. What two factors […]
What is the temperature of the South Equatorial Current?
What is the temperature of the South Equatorial Current? The average temperature of the South Equatorial Current is about 26°-28°C near the surface and 22°-24°C at 100 m depth (Mayer and al., 1998). The annual cycle of temperature is relatively stable between March and September, the two seasonal extremes, with a variability of about 4°C. […]
What is the effect of hysteresis?
What is the effect of hysteresis? The magnetization of ferromagnetic substances due to a varying magnetic field lags behind the field. This effect is called hysteresis, and the term is used to describe any system in whose response depends not only on its current state, but also upon its past history. Is an example of […]
Does magic work on Superman?
Does magic work on Superman? The reason for this is simple – his powers occurred as a result of a natural phenomenon, rather than anything supernatural. This means that magic affects him the way it affects anyone else; he’s just as vulnerable to it as normal humans are. In fact, magic seems to have very […]
What are the two kinds of electrostatic charges?
What are the two kinds of electrostatic charges? Electric charges are of two general types: positive and negative. Two objects that have an excess of one type of charge exert a force of repulsion on each other when relatively close together. Where is the lower end of lightning conductor fixed and how? Lightning conductor consists […]
