Treat the Earth as if it were a perfect sphere of radiusR. Suppose that you are on the topof a tower of heighthabove the surface of the Earth. Show that distance along the Earth thatyou see from your vantage point to the horizon iss=√2Rh. Hint: Show thath/R=1cosθ−1,whereθis the subtended angle from your vantage point to the horizon and the arclength alongthe Earth iss=Rθ. Solveθby expanding these expressions as necessary.

The earth (of radius of 6371km) rotates on itself at a rate of one revolution every 24 hours and is titled by an angle of 23.5°. Let's assume that the earth is a perfect sphere, which allows us to consider a uniform circular motion 23.5 R equator Figure 1: Earth rotation Everybody on earth share the same time of rotation, but based on their location on the earth, they wil have different velocities. A person located in Hawaii, at an...
2. One assumption that Eratosthenes made was that the earth was a perfect sphere. What are 5 other assumptions critical to this calculation? Eratosthenes was a Greek mathematician who lived 276-194 BC. At summer solstice he waited until noon, when the sun was directly overhead in Aswan. He placed a gnomon (basically a stick) at the bottom of the well at 90° to the ground, and noticed that it cast no shadow. Then at the same time he had others...
just need part (a)
Assume that the earth is a perfect sphere of radius 3960 miles. By the heading, h(ã, P), of a directed, great circle arc a at the point P on the arc we mean the angle made with the "latitude" circle. You are to "file a flight plan" for a direct flight from Syracuse to Cape Town, South Africa. Assume that the map coordinates of Syracuse are 43°N, 76oW and the map coordinates of Cape Town are...

PRECALCULUS: VECTORS Directions: Suppose that you plan to take a trip to your dream destination. You would like to know the shortest distance between your starting point and your destination. When calculating distances on a plane, you need only consider two dimensions because you are on a flat surface. However, when finding distances between two points on Earth, you must take into the account the curvature of...
BOX 5.1 The Polar Coordinate Basis Consider ordinary polar coordinates r and 0 (see figure 5.3). Note that the distance between two points with the same r coordinate but separated by an infinitesimal step do in 0 is r do (by the definition of angle). So there are (at least) two ways to define a basis vector for the direction (which we define to be tangent to the r = constant curve): (1) we could define a basis vector es...
Sorry this problem has so many
parts--thank you in advance for your effort.
Conservative Forces It takes work to lift an object under the influence of the Earth's gravitational force. This increases the gravitational potential energy of the object. Lowering the ob- ject releases the gravitational potential energy that was stored when it was lifted. When you studied the gravitational force, you applied the term conservative to it because it allows the recovery of all of the stored energy. You...
if you could do these for me that's be great there
really easy I just want to make sure I did them right
Serena Williams Due January 16 at 9 a.m. The Global Positioning System allows for the location on Earth's surface to an accuracy of a few meters. Satellites orbit Earth at locations that are known accurately. They transmit a signal that conveys which satellite it is, its location, and the time the signal was sent. Suppose the ith...
Fields on the Page Estimate the maximum magnitudes of the electric and magnetic fields of the light that is incident on a page because of the visible light coming from your desk lamp. Treat the lightbulb as a point source of electromagnetic radiation that is 6% efficient at transforming energy coming in by electrical transmission to energy leaving by visible light. SOLUTION Conceptualize The filament in your lightbulb emits electromagnetic radiation. The brighter the light, the larger the magnitudes of...
Consider a cylindrical capacitor like that shown in Fig. 24.6. Let d = rb − ra be the spacing between the inner and outer conductors. (a) Let the radii of the two conductors be only slightly different, so that d << ra. Show that the result derived in Example 24.4 (Section 24.1) for the capacitance of a cylindrical capacitor then reduces to Eq. (24.2), the equation for the capacitance of a parallel-plate capacitor, with A being the surface area of...
