Does spring constant depend on gravity? Gravity has nothing to do with the spring constant. It can only effect the net force on the spring depending on the orientation of the spring. If the spring is oriented horizontally, gravity has no effect. Does spring constant change with compression? The proportional constant k is called the […]
Can fossils be found anywhere?
Can fossils be found anywhere? For example, many fossils form when plant and animal remains are buried by mud, sand, or soil. This helps to preserve the remains long enough for them to form fossils. Still, fossils can be found just about anywhere. From the tops of mountains to the depths of the seas, fossils […]
What does hypothesis mean in simple terms?
What does hypothesis mean in simple terms? A hypothesis is a suggested solution for an unexplained occurrence that does not fit into current accepted scientific theory. The basic idea of a hypothesis is that there is no pre-determined outcome. What is the best definition for the word prediction? A prediction is what someone thinks will […]
What is the highest sea level in history?
What is the highest sea level in history? The current sea level is about 130 metres higher than the historical minimum. Historically low levels were reached during the Last Glacial Maximum (LGM), about 20,000 years ago. The last time the sea level was higher than today was during the Eemian, about 130,000 years ago. Will […]
When carbon reacts with a small amount of oxygen?
When carbon reacts with a small amount of oxygen? When carbon is oxidized in a small amount of oxygen, the principle product formed is carbon monoxide (CO), when the oxidation occurs in a higher concentration of oxygen, the principle product formed is carbon dioxide (CO2). What happens when carbon reacts with excess of oxygen? Carbon […]
Is biome a ecosystem?
Is biome a ecosystem? A biome is a large region of the world that has similar plants, animals and other organisms that are adapted to the terrain and weather of that region. An ecosystem is the interaction of plants and animals with nonliving things and each other. Is ecosystem bigger than community? The population, which […]
What is meant by components of velocity?
What is meant by components of velocity? Determining the Components of a Velocity Vector The two parts of a vector are known as components and describe the influence of that vector in a single direction. If a projectile is launched at an angle to the horizontal, then the initial velocity of the projectile has both […]
How does frequency affect interference?
How does frequency affect interference? A higher frequency corresponds to a shorter wavelength. Waves of shorter wavelength spread out (diffract) less after passing through the slits, and the short wavelength leads to a smaller angle at which constructive interference (one wavelength path difference between the two waves) will occur. What is interference effect? Interference, in […]
Is a guitar string a standing wave?
Is a guitar string a standing wave? A guitar string sound consists of standing waves: the fundamental and overtones. The fundamental wavelengh is twice the length of the vibrating part of the string. What type of wave does a guitar make? Longitudinal Waves What is the frequency of low E on a guitar? 82 Hz […]
