How do heavier elements formed in stellar nucleosynthesis? Mar. 18, 2019 — Heavy elements are produced during stellar explosion or on the surfaces of neutron stars through the capture of hydrogen nuclei (protons). What is r in the r process? In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set […]

In which glass of water did the salt dissolve faster? Salt does dissolve quicker in room temperature water than in cold water. In fact, you can take that even further, and say that any solid substance that can dissolve in water, will dissolve quicker in hot water than room temperature water. What are the two […]

What is the difference between chyme and bile? Chyme is different from bile because chyme is actually mixed with bile to lower its pH. Chyme is found in the stomach (it is the partially digested food) and the bile can be located in the liver. It helps to digest the food. What nutrients are absorbed […]

Why is 45 degrees maximum range? The sine function reaches its largest output value, 1, with an input angle of 90 degrees, so we can see that for the longest-range punts 2θ = 90 degrees and, therefore, θ = 45 degrees. A projectile, in other words, travels the farthest when it is launched at an […]

Which chemical equation is unbalanced? According to the law of conservation of, the number of atoms in the products of a chemical reaction must be balanced with the number of atoms in the reactants. The chemical equation for the formation of ammonia is unbalanced. Which is an example of chemical change quizlet? Define a chemical […]

How do you know if an electron will be ejected? The number of electrons ejected can be determined by measuring the current between the wire and plate. In equation form, the photon energyis E = hf, where E is the energy of a photon of frequency f and h is Planck’s constant. What is difference […]

Why is it called a shield volcano? Illustrated Volcano Glossary Shield volcanoes are volcanoes that mainly erupt fluid (usually basaltic) lava flows that are able to travel over long distances and thus construct over time broad, gentle slopes. They are called shield volcanoes, because they resemble the shape of a warriors’shield. How dangerous is a […]

How do you calculate cooling capacity of a heat exchanger? Using the energy equation of Q = ṁ x Cp x ΔT we can calculate the cooling capacity. We add 273.15K to the celcius to convert it to units of Kelvin. The Specific heat capacity (Cp) is measured in units of kJ per kg per […]

Does anyone know anyone? ‘Anybody’ is a third person singular form and takes -s in the present simple tense. That’s why the question form requires -s and ‘Does anybody’ is correct. The same would apply to ‘Does anyone’, ‘Does anything’ etc. What is the difference of do and are? We use does and is with […]

What is mechanical energy give two examples? A moving car possesses mechanical energy due to its motion (kinetic energy). A moving baseball possesses mechanical energy due to both its high speed (kinetic energy) and its vertical position above the ground (gravitational potential energy). How many types of mechanical energy explain it? two types Does a […]
