Q: Answer the following question given this paragraph: The average particle energy needed to observe 19 GeV . (a) What unification of forces is estimated to be 10 is the rest mass in kilograms of a particle that has a rest mass 19 of 10 GeV/c 2 ? (b) How many times the mass of a hydrogen atom is this? 14. The peak intensity of the CMBR occurs at a wavelength of 1.1 mm. (a) What is the energy in eV of a 1.1-mm photon? (b) 9 There are approximately 10 photons for each massive 9 particle in deep space. Calculate the energy of 10 such photons. (c) If the average massive particle in space has a mass half that of a proton, what energy would be created by converting its mass to energy? (d) Does this imply that space is "matter dominated"? Explain briefly. (a) What Hubble constant corresponds to an approximate 10 age of the universe of 10 y? To get an approximate value, assume the expansion rate is constant and calculate the speed at which two galaxies must move apart to be separated by 1 Mly (present average galactic separation) in a time of 10 10 y. (b) Similarly, what Hubble constant corresponds to a 10 universe approximately 210 -y old? 16. Show that the velocity of a star orbiting its galaxy in a circular orbit is inversely proportional to the square root of its orbital radius, assuming the mass of the stars inside its orbit acts like a single mass at the center of the galaxy. You may use an equation from a previous chapter to support your conclusion, but you must justify its use and define all terms used. The core of a star collapses during a supernova, forming a neutron star. Angular momentum of the core is conserved, and so the neutron star spins rapidly. If the initial core radius 5 is 5.010 km and it collapses to 10.0 km, find the neutron star's angular velocity in revolutions per second, given the core's angular velocity was originally 1 revolution per 30.0 days. Using data from the previous problem, find the increase in rotational kinetic energy, given the core's mass is 1.3 times that of our Sun. Where does this increase in kinetic energy come from? 19....

Answer the following question given this paragraph: Different types of cells in the human body are specialized for specific jobs. Do you know the functions of any of the cell types shown here?. Q: In humans and other multicellular organisms, different types of what basic structures are specialized for specific jobs? A:
****
A: cells

Answer the following question given this paragraph: Beta () decay is a more complicated process. Unlike the -emission, which simply expels a particle, the -emission involves the transformation of a neutron in the nucleus to a proton and an electron. The electron is then ejected from the nucleus. In the process, the atomic number increases by one while the atomic weight stays the same. As is the case with -emissions, -emissions are often accompanied by -radiation. Q: How does the atomic number change during beta emission? A:
OPTIONS:
- stays the same
- increases by two
- decreases by one
- increases by one
increases by one

Answer the following question given this paragraph: The red liquid in this thermometer is alcohol. Alcohol expands uniformly over a wide range of temperatures. This makes it ideal for use in thermometers. Q: How does alcohol expand over a wide range of temperatures? A:
OPTIONS:
- variably
- exponentially
- erratically
- uniformly

Answer: uniformly

Question: Answer the following question given this paragraph: Water potential is a measure of the potential energy in water. Plant physiologists are not interested in the energy in any one particular aqueous system, but are very interested in water movement between two systems. In practical terms, therefore, water potential is the difference in potential energy between a given water sample and pure water (at atmospheric pressure and ambient temperature). Water potential is denoted by the Greek letter (psi) and is expressed in units of pressure (pressure is a form of energy) called megapascals (MPa). The potential of pure water (wpure H2O) is, by convenience of definition, designated a value of zero (even though pure water contains plenty of potential energy, that energy is ignored). Water potential values for the water in a plant root, stem, or leaf are therefore expressed relative to wpure H2O. The water potential in plant solutions is influenced by solute concentration, pressure, gravity, and factors called matrix effects. Water potential can be broken down into its individual components using the following equation:. Q: What is the measure of water potential? A:
OPTIONS:
- trials
- fluctuations
- spores
- megapascals
Answer: megapascals
