How does friction affect total mechanical energy? Mechanical energy is reduced due to friction and converted to heat. This is the reason why there is an increase in temperature in objects that move against each other. The role of friction in a closed system is to convert a part of the total energy to heat. […]
What motion is illustrated by a ball thrown horizontally?
What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]
What are the three main physical properties of sound waves?
What are the three main physical properties of sound waves? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. […]

What is the amount of matter called?
What is the amount of matter called? Mass is a measure of the amount of matter in a substance or an object. What gives us mass? The strong force and you The Higgs field gives mass to fundamental particles—the electrons, quarks and other building blocks that cannot be broken into smaller parts. The energy of […]
How do I know if my photo tube is bad?
How does the urinary and digestive system work together?
How does the urinary and digestive system work together? The urinary system works as a filter, removing toxins and wastes from your body through urine. It uses a series of tubes and ducts to pass this waste. These tubes are connected to your blood vessels and digestive system. How do the digestive system and the […]
How high or low a sound seems to a listener is its?
How high or low a sound seems to a listener is its? How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for […]
How much light is there in the universe?
How much light is there in the universe? According to calculations, the current comoving distance—proper distance, which takes into account that the universe has expanded since the light was emitted—to particles from which the cosmic microwave background radiation (CMBR) was emitted, which represents the radius of the visible universe, is about 14.0 billion … How […]
What is a disadvantage of using nuclear power?
What is a disadvantage of using nuclear power? Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste. What is the cheapest form of electricity? solar […]
