(4) Suppose that the Arctic Circle is at latitude 65° north of the Equator. North of the e of the...
. Las Vegas is located at 36.1 north latitude and 115.2 west longitude. Rome, Italy is located at 41.9 north latitude and 12.5 east longitude. What is the length of the shortest path along the surface of the Earth that joins these two cities? The circumference of the Earth as 40,000 km
Suppose two highly precise, identical clocks are synchronized and one clock is placed on the North Pole and the other on the equator. After 310 years, how much will the clocks differ in time? Assume the Earth is a perfect sphere.
Earth's magnetic field at the equator is directed horizontally from south to north and has a strength of 0.310 gauss. Suppose copper wire with mass of 12g and length of 10m could be placed in the B-field without support. Determine the magnitude and direction of the minimum current required in the wire so it just floats above the surface of the Earth. (1 gauss= 10^-4T)
Reproducibility To reproduce an observation, you need to know all of the important circumstances of the observation. For example, consider the observation that the sun rises in the East and sets in the West every 24 hours Someone who repeats that observation in Murmansk, Russia, during midsummer will see the Sun circle the sky without ever completely setting at all. An important detail has been omitted: The observation must be made "in this part of the world in modern terms,...
Q) The boundary between the Pacific and the North American plate along the San Andreas fault is a _____ plate boundary, and the boundary between the Nazca Plate and the South American plate along the coast of Chile is a _____ plate boundary. transform; divergent convergent; transform transform; convergent convergent; divergent Q) In the rock cycle, ______rocks are created from magma, while _____rocks are created by applying heat or pressure to existing rocks and thus changing their mineral structure. metamorphic;...
At the equator, the earth’s field is essentially horizontal; near the north pole, it is nearly vertical. In between, the angle varies. As you move farther north, the dip angle, the angle of the earth’s field below horizontal, steadily increases. Green turtles seem to use this dip angle to determine their latitude. Suppose you are a researcher wanting to test this idea. You have gathered green turtle hatchlings from a beach where the magnetic field strength is 50 μT and...
Visitor from Con Ed from a galaxy far away have placed a large (black) ring of wire in the arctic circle around the geographic north pole of the earth. Now they are reducing the earth's magnetic field (but not changing its sign) to induce electric current in their large ring of wire. As seen from far above the north pole of the earth, is their current flowing CLOCKWISE or COUNTER-CLOCKWISE?
Suppose we synchronize two atomic clocks at a point at 45° south latitude, and then move one clock directly north to the earth's equator and the other directly south to the south pole, where they remain for some years in climate-controlled enclosures that keep them at the same temperature and humidity. We then reunite the clocks at the origin point and compare them again. Which (if either) has registered a shorter time between the synchronization and comparison events? A. The...
3. Suppose the Earth is rotated so that its north pole goes to 20° north, 10° west in the original longitude and latitude system and that the 25° west meridian points due south (in the original system). (a) What are the Euler angles describing this rotation? (b) Find the transformation matrix S describing the rotation.
5. (a) 4points Figure 2 below shows the annual average radiation budget as a function of latitude. Estimate the latitude Lc where the net radiation crosses over from positive to negative in the Northern Hemisphere. Also estimate the value of the net radiation at the North Pole. Use the two pieces of information to find the equation of a straight line that approximately describes the net radiation (in WIm2) as a function of latitude L between 10 N and the...
