To describe:
The straightest possible path on Earth Surface.

Answer to Problem 1EAP
Solution:
Straightest possible paths are followed by the explorers, while these “straight” lines are following the curved surface of the earth. Travelers are moving in opposite directions along paths.
Explanation of Solution
Introduction:
Considering the Earth’s surface and describing the straightest possible path.
Straightest possible paths are followed by the explorers, while these “straight” lines are following the curved surface of the earth. Travelers are moving in opposite directions along the paths. Paths are as straight as possible, and they will meet as they go around the earth, and this fact that we attribute to the curvature of the earth’s surface.
Conclusion:
Paths are as straight as possible, and they will meet as they go around the earth, and this fact that we attribute to the curvature of the earth’s surface.

- Consider a uniformly charged ring of radius R with total charge Q, centered at the origin inthe xy-plane. Find the electric field (as a vector) at a point on the z-axis at a distance z above thecenter of the ring. Assume the charge density is constant along the ring.arrow_forward3) If the slider block C is moving at 3m/s, determine the angular velocity of BC and the crank AB at the instant shown.

A motorboat traveling 6 m/s, West encounters a water current travelling 3.5 m/s, South. a) Draw a vector diagram showing the resultant velocity, then determine the resultant velocity of the motorboat. b) If the width of the river is 112 m wide, then how much time does it take for the boat to travel shore to shore? c) What distance downstream does the boat reach the opposite shore?arrow_forwardLake Erie contains roughly 4.00⋅10114.00⋅1011 m3 of water. Assume the density of this water is 1000. kg/m3 and the specific heat of water is 4186 J/kg˚C. It takes 2.31x10^19 J of energy to raise the temperature of that volume of water from 12.0 °C to 25.8 ˚C. An electric power plant can produce about 1110 MW. How many years would it take to supply this amount of energy by using the 1110 MW from an electric power plant?arrow_forward
