Assume that a viral DNA molecule is a 11-μm-long strand with a uniform 20-Å diameter. Assuming complete flexibility of the molecule, will it fit inside a viral head that is a 8×10−2-μm-diameter sphere? Part A)What is the volume of the viral head in cubic angstrom (Å3)? Hint: Recall that the volume of a sphere can be calculated using this formula: Volume= (4/3) x pi x r2, where r stands for radius of the sphere. Also note that 1Å=0.1 nm. Express...

) Distance from Earth to Moon is about 2.39×105 miles. Assuming that a spacecraft can take off from Earth, attain escape velocity (see part (C)) and directly get to the Moon and land, what would be the time taken for travel to the Moon? Apollo 11 astronauts reached Moon in 4 days, 6 hours and 45 minutes in July 1969. It is not really practical to go to Moon in one shot. One way is to get a craft to...

1. The moon orbits the earth at a distance of 3.85 times 10^8 m. Assume that this distance is between the centers of the earth and the moon and that the mass of the earth is 5.98 x 10^24 kg. Find the period for the moon's motion around the earth. Express the answer in days. 2. A 0.0296 kg ball is shot from the plunger of a pinball machine. Because of a centripetal force of 0.0485 N, the ball follows...

For each of the following, you’ll need to perform dimensional analyses. Show your work, use significant figures and show all conversion factors you use. You may need to use some of the conversion factors or equations below and you many need to look some up. 1 mole = 6.02x1023 atoms mass of a gold atom = 3.27 x 10-22 g radius of a gold atom = 174 picometers density of gold = 19.3 g/mL volume of a sphere = 4/3πr3...
