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 […]
What are the positive effects of a volcano?
What are the positive effects of a volcano? Volcanoes can provide people with many benefits such as: volcanic rock and ash provide fertile land which results in a higher crop yield for farmers. tourists are attracted to the volcano, which increases money to the local economy. geothermal energy can be harnessed, which provides free electricity […]
Can you differentiate tangential velocity and tangential acceleration?
Can you differentiate tangential velocity and tangential acceleration? If the tangential velocity is not changing directions, then the object is not moving in a circle. Tangential acceleration results from the change in magnitude of the tangential velocity of an object. An object can move in a circle and not have any tangential acceleration. How do […]
How much time is a parsec?
How much time is a parsec? It is defined as 360×60×60/2π astronomical units (AU), which is equivalent to about 19.17 trillion miles, or about 3.262 light-years. The Star Wars parsec appears to be equivalent to the real-world measurement: The Essential Atlas says a parsec is 3.26 light-years. How many parsecs are in the universe? The […]
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 difference between solar time and solar day?
What is the difference between solar time and solar day? The sidereal day is measured with respect to the stars, while the solar day is the length of time measured from noon to noon. By noon, we mean the time when the Sun passes the celestial meridian, reaching its maximum height in the sky. How […]
What is the relationship between temperature and kinetic energy answers?
What is the relationship between temperature and kinetic energy answers? Kinetic energy is directly proportional to the temperature applied. Basically with increase in temperature the vibration / collision of molecules increase hence kinetic energy increases. What is the relationship between the kinetic energy of molecules in an object? Explanation: The kinetic energy of the molecules […]
Does it matter where you put the dots on a Lewis structure?
Does it matter where you put the dots on a Lewis structure? In almost all cases, chemical bonds are formed by interactions of valence electrons in atoms. To facilitate our understanding of how valence electrons interact, a simple way of representing those valence electrons would be useful. Again, it does not matter on which sides […]
Is damped oscillation?
Is damped oscillation? An oscillator is anything that has a rhythmic periodic response. A damped oscillation means an oscillation that fades away with time. Examples include a swinging pendulum, a weight on a spring, and also a resistor – inductor – capacitor (RLC) circuit. What causes damped oscillation? a decrease in intensity of oscillations with […]
Does photoelectric current depend on frequency?
Does photoelectric current depend on frequency? Photoelectric effect can be explained as: it takes a specific energy to launch an electron from a metal surface. This energy is the work function which relies upon the metal. Electrons can pick up energy by collaborating with photons. Current is not dependent on the frequency of photons. What […]
