) 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...
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...
Jupiter is 300 times more massive than the Earth and 10 times the diameter of the Earth. An astronaut lands on a planet that is the mass of Jupiter but the same radius as the Earth. On this planet the force of gravity is: a) The same as on the surface of Jupiter b) Between that on the Earth and the surface of Jupiter c) The same as on the Earth d) A little bit higher than on the the...
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...
4. The radius of the earth is 6.37X10° meters. Determine the volume of the earth to the correct number of sig. figures. Assume the Earth is a sphere with volume 4 tr/3.
the volume of a sphere is given by v
The volume of a sphere is given by V = (4/3)pi r^3, where r is the radius. Compute the volume of a sphere with a radius of 925 pm. State your answer in units of m^3.
69. Solar Eclipse on Earth The sun has a Sun diameter of about 865,000 mi with a maxi- mum distance from Earth's surface of about Moon Earth 94,500,000 mi. The moon has a smaller diam- eter of 2159 mi. For a total solar eclipse to occur, the moon must pass between Earth and NOT TO SCALE Umbra the sun. The moon must also be close enough to Earth for the moon's umbra (shadow) to reach the surface of Earth. (Source:...
