Does a higher gear ratio mean more torque? A numerically higher axle ratio provides a mechanical advantage to send more of the engine’s available torque to the rear tires (and front tires, in a four-wheel drive vehicle), but you pay the price at the fuel pump. So, a truck with optional 3.73 gears will tow […]
What are the five significant stresses and factors into consideration for aircraft construction?
What are the five significant stresses and factors into consideration for aircraft construction? SPECIFIC ACTION OF STRESSES The fuselage of an aircraft is subject the fives types of stress—torsion, bending, tension, shear, and compression. Why is so important to repair aircraft damage immediately? The satisfactory performance of an aircraft requires continuous maintenance of aircraft structural […]
What happens to the volume of a gas when you double the number of moles of gas?
What happens to the volume of a gas when you double the number of moles of gas? Le Chatelier’s Principle states that: a) When a system at equilibrium is disturbed , a new equilibrium constant is established. What happens to the volume of gas when you double the number of moles of gas while keeping […]
What is the most common geological feature seen on moons?
What is the most common geological feature seen on moons? Craters are the most common surface features on many solid planets and moons—Mercury and our Moon are covered with craters. This portion of the Moon is covered by numerous circular holes. These are impact craters, each of which was formed when an asteroid or comet […]
How can you tell the difference between a longitudinal wave and a transverse wave?
How can you tell the difference between a longitudinal wave and a transverse wave? In the longitudinal wave, the medium moves left to right, while in thee transverse wave, the medium moves vertically up and down. Longitudinal waves have a compression and rarefaction, while the transverse wave has a crest and a trough. Longitudinal waves […]
What happens when two magnets are placed side by side?
What happens when two magnets are placed side by side? Opposite poles of a magnet attract each other, whereas like poles repel each other. However, when lined up with another north-seeking pole, the two magnets would push away from each other because their forces are not compatible. Is Venus a permanent magnet? Venus is a […]
Is there anything more powerful than gamma rays?
Is there anything more powerful than gamma rays? The measurement is exceedingly difficult since cosmic rays can outnumber gamma-rays at these energies by a factor of 10,000 to 1 or more! As the gamma-ray is making its way to our telescopes, it has to traverse through space, where there are photons and particles all around […]
What are two requirements for current flow?
What are two requirements for current flow? To produce an electric current, three things are needed: a supply of electric charges (electrons) which are free to flow, some form of push to move the charges through the circuit and a pathway to carry the charges. The pathway to carry the charges is usually a copper […]
What was Democritus wrong about?
What was Democritus wrong about? 2,500 years ago, Democritus suggested that all matter in the universe was made up of tiny, indivisible, solid objects he called “atomos.” However, other Greek philosophers disliked Democritus’ “atomos” theory because they felt it was illogical. Atoms cannot be subdivided, created, or destroyed. Are we made of atoms? About 99 […]
