Does amplitude increase at natural frequency? When you drive the ball at its natural frequency, the ball’s oscillations increase in amplitude with each oscillation for as long as you drive it. The phenomenon of driving a system with a frequency equal to its natural frequency is called resonance. A system being driven at its natural […]
What is the result of stream erosion?
What is the result of stream erosion? Erosion by Streams Flowing streams pick up and transport weathered materials by eroding sediments from their banks. Streams also carry ions and ionic compounds that dissolve easily in the water. Sediments are carried as the following loads: dissolved, suspended, and bed. What is the long term result of […]

Can a balloon make it to space?
Can a balloon make it to space? A helium-filled balloon can float very high up into the atmosphere, however, it cannot float up into outer space. The balloon can only rise up until the atmosphere surrounding it has the same weight as the helium in the balloon. This happens at about a height of 20 […]
Why is dancing so fun?
Why is dancing so fun? Dancing also improves spatial awareness, as well as raising the heart rate and causing a release of feel-good endorphins into the bloodstream. One more benefit is that it helps reduce levels of cortisol – a stress hormone. Dancing makes you feel good because it makes you feel so alive.” Does […]
Why is deletion mutation harmful?
Why is deletion mutation harmful? Because an insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered. What is the […]
What is enzyme and types?
What is enzyme and types? According to the International Union of Biochemists (I U B), enzymes are divided into six functional classes and are classified based on the type of reaction in which they are used to catalyze. The six kinds of enzymes are hydrolases, oxidoreductases, lyases, transferases, ligases and isomerases. How do you name […]

Is 100% UV protection the same as polarized?
Is 100% UV protection the same as polarized? Polarization and UV Protection Are Not One and the Same This is known as glare. Polarized lenses have a special filter that blocks intense reflected light for better visibility. Images seen through polarized lenses may appear a bit darker than normal, but objects should look clear and […]
What does a wave carry from place to place?
What does a wave carry from place to place? Waves carry energy from one place to another. Because waves carry energy, some waves are used for communication, eg radio and television waves and mobile telephone signals. For example, water waves have to travel in water. Sound waves need a solid, a liquid or a gas […]
