Answer the following question given this paragraph: Water is the solvent in solutions called acids and bases. To understand acids and bases, it is important to know more about pure water, in which nothing is dissolved. In pure water (such as distilled water), a tiny fraction of water molecules naturally breaks down, or dissociates, to form ions. An ion is an electrically charged atom or molecule. The dissociation of pure water into ions is represented by the chemical equation:. Q: Water is the solvent in solutions called acids and? A:
OPTIONS:
- proteins
- alkalines
- nutrients
- bases

Answer: bases

Question: Answer the following question given this paragraph: For decades scientists have had equipment that can measure earthquake magnitude. The earthquake magnitude is the energy released during the quake. Q: What term is used describe energy released during an earthquake? A:
OPTIONS:
- blast
- seismic load
- resonance
- magnitude
Answer: magnitude

input with options: Answer the following question given this paragraph: Early in the development of a human fetus, the skeleton is made entirely of cartilage. The relatively soft cartilage gradually changes to hard bone through ossification. This is a process in which mineral deposits replace cartilage in bone. At birth, several areas of cartilage remain, including the ends of the long bones in the arms and legs. This allows these bones to keep growing in length during childhood. Q: Early in the development of a human fetus, the skeleton is made entirely of what? A:
OPTIONS:
- bones
- anterior
- membrane
- cartilage
output: cartilage

Q: Answer the following question given this paragraph: Figure 27.11 The amplitudes of waves add. (a) Pure constructive interference is obtained when identical waves are in phase. (b) Pure destructive interference occurs when identical waves are exactly out of phase, or shifted by half a wavelength. Q: Pure constructive interference and pure destructive interference are distinguished by whether or not identical waves are what? A:

OPTIONS:
- before phase
- in equilibrium
- after phase
- in phase

A: in phase

input: OPTIONS:
- direction
- speed
- displacement
- velocity Now, answer this question: Answer the following question given this paragraph: Average acceleration is the rate of change of velocity, or the change in velocity per unit time. Q: Average acceleration is the rate of change of what? A:
A:
output: velocity

Question: Answer the following question given this paragraph: 24.4 Energy in Electromagnetic Waves Anyone who has used a microwave oven knows there is energy in electromagnetic waves. Sometimes this energy is obvious, such as in the warmth of the summer sun. Other times it is subtle, such as the unfelt energy of gamma rays, which can destroy living cells. Electromagnetic waves can bring energy into a system by virtue of their electric and magnetic fields. These fields can exert forces and move charges in the system and, thus, do work on them. If the frequency of the electromagnetic wave is the same as the natural frequencies of the system (such as microwaves at the resonant frequency of water molecules), the transfer of energy is much more efficient. Connections: Waves and Particles The behavior of electromagnetic radiation clearly exhibits wave characteristics. But we shall find in later modules that at high frequencies, electromagnetic radiation also exhibits particle characteristics. These particle characteristics will be used to explain more of the properties of the electromagnetic spectrum and to introduce the formal study of modern physics. Another startling discovery of modern physics is that particles, such as electrons and protons, exhibit wave characteristics. This simultaneous sharing of wave and particle properties for all submicroscopic entities is one of the great symmetries in nature. Q: If the frequency of the electromagnetic wave is the same as the natural frequencies of the system, the transfer of what is much more efficient? A:
OPTIONS:
- heat
- sound
- light
- energy
Answer:
energy
