Why is the master cylinder reservoir split into 2 separate units? This is to allow for fluid level changes as the disc pads wear. Inside the master cylinder is a machined bore that contains the master cylinder primary and secondary pistons. Both pistons are combined into a single, two part unit. What are the differences […]

How can you melt ice fast? In a bucket, combine a half-gallon of hot water, about six drops of dish soap, and 1/4 cup of rubbing alcohol. Once you pour the mixture onto your sidewalk or driveway, the snow and ice will begin to bubble up and melt. Just keep a shovel handy to scrape […]

What is the purpose of Galileo? About the mission While its aim was to study Jupiter and its mysterious moons, which it did with much success, NASA’s Galileo mission also became notable for discoveries during its journey to the gas giant. It was the first spacecraft to visit an asteroid — two in fact, Gaspra […]

What is the difference between the ground state and the excited state of an atom quizlet? The ground state is the lowest energy state the electron can occupy. When the electron absorbs energy, it can move to a higher-energy level, or excited state. What does it mean to say that an atom is in an […]

How do you explain ionic bonding? Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion. […]

Is a 100 year old person old and 1000 year old artifact ancient? Answer: the hundred year old person is not ancient since alot of people can move up to a hundred years while the thousand year old artifact is ancient since alot of artifacts break early or a while but some will manage to […]

What is the formula of effort distance? The effort distance (also sometimes called the “effort arm”) is shorter than the resistance distance. Mechanical advantage = |Fr/Fe | where | means “absolute value.” Mechanical advantage is always positive. Switch to a 100 gram mass. What is the efficiency of the machine? The efficiency of a machine […]

Why bandwidth of digital signal is infinite? A true square wave has a vertical line for its face. That is, an increase from Vmin to Vmax in zero seconds. Anything (except zero) divided by zero is infinity. In reality it takes time for the voltage to rise from Vmin to Vmax, and so there is […]

Why do ski jumpers not break their legs? The ski jumpers will intentionally abort their long flying stance to land sooner and also change how they land in order to get an easier landing so they do not hurt themselves. Landing on a flat surface the total force on the legs is almost entirely vertical […]

Can you see in mirrored glass at night? When can you see through mirrored window films? During daylight hours you will be able to see through mirrored window film from the inside out. If it’s brighter inside (usually at night when lights are on in the home) then it will be possible to see through […]
