What was the most common weather? On Earth, the common weather phenomena include wind, cloud, rain, snow, fog and dust storms. Less common events include natural disasters such as tornadoes, hurricanes, typhoons and ice storms. Almost all familiar weather phenomena occur in the troposphere (the lower part of the atmosphere). Does weather affect what we […]

When an electron is removed the atom gets a? If an atom or molecule gains an electron, it becomes negatively charged (an anion), and if it loses an electron, it becomes positively charged (a cation). What is required to remove a second electron? 2nd ionization energy – The energy required to remove a second electron […]

What is the strongest fundamental force? strong nuclear force What are the 4 fundamental forces from weakest to strongest? Actually, gravity is the weakest of the four fundamental forces. Ordered from strongest to weakest, the forces are 1) the strong nuclear force, 2) the electromagnetic force, 3) the weak nuclear force, and 4) gravity. Is […]

Will an electron stay in an excited state without outside energy? Will an electron stay in an excited state without outside energy? An electron does not stay in an excited state for very long – it soon returns to the ground states. When it does so, a photon is emitted that has the same energy […]

What is mass defect formula? The mass defect can be calculated using equation Δm = [Z(mp + me) + (A – Z)mn] – matom, where: Δm = mass defect [atomic mass unit (amu)]; mp = mass of a proton (1.007277 amu); mn = mass of a neutron (1.008665 amu); me = mass of an electron […]

Is modulus a function? A modulus function is a function which gives the absolute value of a number or variable. It produces the magnitude of the number of variables. It is also termed as an absolute value function. The outcome of this function is always positive, no matter what input has been given to the […]

Who selects the floor leaders in each house? The Senate Republican and Democratic floor leaders are elected by the members of their party in the Senate at the beginning of each Congress. Depending on which party is in power, one serves as majority leader and the other as minority leader. The leaders serve as spokespersons […]

What is an example of inclusion? Inclusion is defined as the state of being included or being made a part of something. When a book covers many different ideas and subjects, it is an example of the inclusion of many ideas. When multiple people are all invited to be part of a group, this is […]

What replaces the electrons that are lost by energized photosystem I? The electron arrives at photosystem I and joins the P700 special pair of chlorophylls in the reaction center. The special pair’s missing electron is replaced by a new electron from PSII (arriving via the electron transport chain). NADPH formation. What supplies the electrons that […]

What is electricity and its types? Electricity is a concept that many are unfamiliar with. There are two main types of electricity, Static Electricity, generated by rubbing two or more objects causing to build up friction, Current Electricity, generated by the flow of electrical charge through a conductor across an electrical field. How is voltage […]
