An object travels from the South Pole along the Prime Meridian to the equator. It mow moves from the equator to (0o, 56oE) and then to (28oS, 56oE). What total distance, in miles, did the object travel? Hint: At the equator 1o= 69.2 miles.

A projectile is launched due north from a point in colatitude
at an angle
to the horizontal, and aimed at a target whose distance is y
(small compared to Earth's radius R). Show that if no allowance is
made for the effects of the Coriolis force, the projectile will
miss its target by a distance
Evaluate this distance if
and y=40km. Why is it that the deviation is to the east near the
north pole, but to the west both...

Part A The earth's radius is about 4000 miles. Kampala, the capital of Uganda, and Singapore are both nearty on the equator. The distance between them is 5000 miles as measured along the earth's surface. The flight from Kampala to Singapore takes 9.2 hours. What is the plane's angular velocity relative to the earth's surface? Give your answer in h. Express your answer using two significant figures.

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)

A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if (a) its initial speed is 0.437 of the escape speed from Earth and (b) its initial kinetic energy is 0.437 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.)

A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if a) its initial speed is 0.365 of the escape speed from Earth and b) its initial kinetic energy is 0.365 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.) c) What is the least initial mechanical energy required at launch if the...

A projectile is shot directly away from Earth's surface. Neglect the rotation of the Earth. What multiple of Earth's radius RE gives the radial distance (from the Earth's center) the projectile reaches if (a) its initial speed is 0.662 of the escape speed from Earth and (b) its initial kinetic energy is 0.662 of the kinetic energy required to escape Earth? (Give your answers as unitless numbers.) (c) What is the least initial mechanical energy required at launch if the...

Canadian geese migrate essentially along a north-south direction for well over a thousand kilometers in some cases, traveling at speeds up to about 100 km/h. If one such bird is flying at 100 km/h relative to the air, but there is a 38.0 km/h wind blowing from west to east. A)At what angle relative to the north-south direction should this bird head so that it will be traveling directly southward relative to the ground? Express your answer in degrees. B)...

40 A projectile is shot directly away from Earth's surface. Neglect the rotation of Earth. What multiple of Earth's radius Rg gives the radial distance a projectile reaches if (a) its initial speed is 0.500 of the escape speed from Earth and (b) its initial kinetic en- ergy is 0.500 of the kinetic energy required to escape Earth? (c) What is the least initial mechanical energy required at launch if the projectile is to escape Earth?

North Celestial Pole Polaris celes South Celestial Pole ChapterPatt The stars look as if they are attached to a sphere that surrounds the earth, the Celestial Sphere. We now know that stars are really at different distances from the Earth, but we still use the Celestial Sphere model as a convenient map of the stars. The Celestial Sphere appears to rotate from East to West, carrying each star completely around in slightly less than 24 hours. The time for one...
