Answer the following question given this paragraph: Figure 8.11 The sun emits energy in the form of electromagnetic radiation. This radiation exists at different wavelengths, each of which has its own characteristic energy. All electromagnetic radiation, including visible light, is characterized by its wavelength. Q: What form of radiation is the energy emitted by the sun? Choices: - seismic - magnetic - thermal - electromagnetic A:
electromagnetic

Answer the following question given this paragraph: At the beginning of the reaction, only the reactants A and B are present. Recall that over the course of a reaction, the reaction rate slows down. This is because the rate depends on the concentrations of one or more reactants. As the reactants are used up, their concentrations drop, thus decreasing the reaction rate. Q: What happens to the reaction rate over the course of a reaction? Choices: - reverses - stays the same - speeds up - slows down A:
(Answer)
slows down
Ques: Answer the following question given this paragraph: Q: The chloroplast integrates the two stages of what process? Choices: - breathing - defacation - polarization - photosynthesis A:
Ans: photosynthesis
(Q).
Answer the following question given this paragraph: The strong nuclear force is a force of attraction between fundamental particles called quarks, which have a type of charge called color charge. The strong nuclear force is transferred between quarks by fundamental force-carrying particles called gluons. Both protons and neutrons consist of quarks. The exchange of gluons holds quarks together within a proton or neutron. Excess, or residual, strong force holds together protons and neutrons in the nucleus. The strong nuclear force is strong enough to overcome the electromagnetic force of repulsion pushing protons apart. Both forces are represented in the Figure below . Q: What is the force of attraction between fundamental particles called quarks, called. Choices: - magnetism - gravity - weak nuclear force - strong nuclear force A:
(A).
strong nuclear force
Ques:Answer the following question given this paragraph: The mass lost in mass defect has gone into energy that is called binding energy. Q: The mass lost in mass defect has gone into energy called what? Choices: - momentum - enthalpy - kinetic energy - binding energy A:

Ans:binding energy
Question: Answer the following question given this paragraph: 28.2 Simultaneity And Time Dilation Two events are defined to be simultaneous if an observer measures them as occurring at the same time. They are not necessarily simultaneous to all observerssimultaneity is not absolute. Time dilation is the phenomenon of time passing slower for an observer who is moving relative to another observer. Observers moving at a relative velocity v do not measure the same elapsed time for an event. Proper time t 0 is the time measured by an observer at rest relative to the event being observed. Proper time is related to the time by an Earth-bound observer by the equation. Q: Two events are defined to be simultaneous if an observer measures them as occurring at what? Choices: - midnight - opposite times - different times - same time A:
Answer:
same time
