- Estimate the age of the universe (in Gyrs) at the time when radiation was emitted from an object with redshift z. For 1 < z < 3200, you can assume the Universe is matter dominated, in which case a ∝ t^2/3 and equation 5.102 should hold. Values: Assume H0 = 70 km/s/Mpc Ωm,0 = 0.3 z=3.6 Equation 5.102 is : a(t) = (3/2 (sqrtΩm,0 ) H0 t)^2/3How do I Identify this problem? What is the problem asking for? (Distance, time, speed, acceleration, energy, a comparison between two values?) - What are the units that the answer should be in? (a) Using data from Table 7.1, calculate the mass converted to energy by the fission of 1.00 kg of uranium. (b) What is the ratio of mass destroyed to the original mass, Δ?/??Provide the answers in 2 hours, and count as 2 questions if necessary.

HINT: 1 MeV = 1.6x10-13 JWe are going to make a simple approximation of the number of atoms in the universe. 1. Assume all the atoms in the universe are hydrogen. (In actual practice, over 75% of the atoms in the universe are hydrogen.) 2. Assume the sun is a typical star (made of pure hydrogen) has a density of 1.4 g/cm3 and is a sphere with a radius of 7.0*108m 3. Assume that there are 100 billion stars in our Milky Way galaxy that are identical to our sun. 4. Assume that there are 10 billion galaxies in the universe identical to our Milky Way galaxy.A 4.6 kg rocket is launched directly upward from Earth at 9.00 km/s (rE = 6.38 x 10^ 6m, mE = 5.98 x 10^24 kg, G =6.67 x 10^-11N. m2 /kg2)a) What altitude above Earth's surface does the rocket reach? b) What is the binding energy at that altitude?
- A particle has a charge of q = +4.6 µC and is located at the origin. As the drawing shows, an electric field of Ex = +236 N/C exists along the +x axis. A magnetic field also exists, and its x and y components are Bx = +1.4 T and By = +1.1 T. Calculate the force (magnitude and direction) exerted on the particle by each of the three fields when it is (a) stationary, (b) moving along the +x axis at a speed of 345 m/s, and (c) moving along the +z axis at a speed of 345 m/s. +Z ہے By Ex Bx +xSuppose that the universe were full of spherical objects, each of mass m and radius r . If the objects were distributed uniformly throughout the universe, what number density (#/m3) of spherical objects would be required to make the density equal to the critical density of our Universe? Values: m = 4 kg r = 0.0407 m Answer must be in scientific notation and include zero decimal places (1 sig fig --- e.g., 1234 should be written as 1*10^3)Find the kinetic energy of the objects in the scenarios.
