You are on Earth, approximated as a perfect sphere with radius R = 6371 km. (a) Imagine you are standing on North Pole, and draw a circle centered around you with a radius r. Express the circumference of the circle in terms of the circle radius r and the Earth radius R. (b) If you can measure distances with an error of ±1 meter, how large a circle would you have to draw on the Earth’s surface to convince yourself that the Earth is spherical rather than flat?

The Earth is approximately a large sphere. The Earth has a radius of 6.378 x 103km and an equatorial circumference of 4.007 x 104 km. Imagine that you wrapped a belt snugly around the equator. It would have a length of 4.007 x 104 km. Now imagine that you wanted to add some material to the belt so that when it encircled the Earth it would be 2.0 m above the surface at every point How much additional material would...

If the earth is a perfect sphere, spinning with angular velocity, Ω. You are standing on the surface of the earth, at the latitude of New York, and you drop a rock. If you draw a line from the rock to the center of the earth, it would intersect the ground at a point X. a) What are the forces on the rock, in your rotating reference frame, at the instant you let go of the rock, but before it...

Suppose the earth is a perfect sphere, spinning with its usual angular velocity, Ω. You are ~ standing on the surface of the earth, at 40 degrees N latitude, and you drop a rock. If you draw a line from the rock to the center of the earth, it would intersect the ground at a point X. (a) Write down the forces on the rock, in your rotating reference frame, at the instant you let go of the rock, but...

Assume the earth is a uniform sphere of mass M and radius R. As strange as it may sound, if one can dig a long tunnel from one side of the Earth straight through the center and exit the other end, any object falling into the tunnel will appear at the other end (i.e. the opposite side of the Earth) in just 2530 s (42.2 min). Call that time t. Let t be a function of G, M, and R,...

- You find a smooth, spherical crystal ball of radius R = 4 cm, and you wish to determine its index of refraction n. (Note, the crystal ball is transparent, made of a uniform material, and has no bubbles or defects inside.) When the sun is directly overhead, an image of the sun forms on the ground when the ball is a distance ℎ = 2.35 cm above the ground. For your work below, treat the sun as a point...
