A neutron lives 900 s when at rest relative to an observer. How fast is the neutron moving relative to an observer who measures its life span to be 2065 s?
Since 1995, hundreds of extrasolar planets have been discovered. There is the exciting possibility that there is life on one or more of these planets. To support life similar to that on the Earth, the planet must have liquid water. For an Earth-like planet orbiting a star like the Sun, this requirement means that the planet must be within a habitable zone of 0.9 AU to 1.4 AU from the star. The semimajor axis of an extrasolar planet is inferred from its period. What range in periods corresponds to the habitable zone for an Earth-like Planet orbiting a Sun-like star?
How much energy does a 2.0 kg mass gain if its speed changes from 2.0 m/s to 4.0 m/s? ( a) 12
P = mgh for h ( potential energy = mass times gravity times height)
The sun produces energy by nuclear fusion reactions, in which matter is converted into energy. By measuring the amount of energy we receive from the sun, we know that it is producing energy at a rate of 3.8 * 1026 W. (a) How many kilograms of matter does the sun lose each second? Approximately how many tons of matter is this (1 ton = 2000 lb)? (b) At this rate, how long would it take the sun to use up all its mass?
The energy of a moving object is given by the equation of E= 12??212mv2 . What is the constant? What type of variation is this? If the energy is 16 joules and the mass is 1 kg (kilogram), what is the velocity?
Problem 1. Mass-Energy conversion in the Sun (Palen, et. al. 3rd Edition, Chapter 11, problems 38, 39) The Sun produces energy by converting mass m into energy E according to E = mc2 where c is the speed of light (c = 300,000 km/sec). Show that if the Sun produces 3.85 × 1026 joules (J) of energy per second, it must convert 4.3 billion kg of mass per second into energy. Note that 1 J/s is a watt (W), which may be more familiar to you. How much mass has the Sun lost over its lifetime (4.5 billion years)? The current mass of the Sun is 2 × 1030. What fraction of this mass has been converted into energy during the Sun’s lifetime?
The highest-energy cosmic ray ever detected had an energy of about 3.0 x 1020 eV. Assume that this cosmic ray was a proton.a. What was the proton’s speed as a fraction of c?b. If this proton started at the same time and place as a photon traveling at the speed of light, how far behind the photon would it be after traveling for 1 ly?
A light-year is the distance light travels in one year (at speed = 2.998 ? 108 ?⁄?) (a) How manymeters are there in 1.00 light-year? (b) An astronomical unit (AU) is the average distance from the Sunto Earth, 1.50 ? 108 ??. How many AU are there in 1.00 light-year?
