1. Imagine you are Alfred Wegener. Write a one- paragraph statement to summarize your work. Your summary must include descriptions on:
a. What your map shows about the Earth 225 million years ago (What does the map show?)
b. How the fossil evidence helped you to put the landmasses together (What was your process?)
c. Why the fossil evidence is good (Why do you think your map is a good one?)

Aperson standing in a canoe exerts a force of 700 n to throw an anchor over the side. find the acceleration of the canoe if the total mass of the canoe and the person is 100 kg?

The heliocentric and the geocentric models of the solar system included these central principles

Consider a uniformly charged ring in the xy plane, centered at the origin. the ring has radius a and positive charge qdistributed evenly along its circumference. a)what is the direction of the electric field at any point on the z axis? . b)what is the magnitude of the electric field along the positive z axis? use k in your answer, where k=14πϵ0. d)the ball will oscillate along the z axis between z=d and z=−d in simple harmonic motion. what will be the angular frequency ω of these oscillations? use the approximation d≪a to simplify your calculation; that is, assume that d2+a2≈a2. express your answer in terms of given charges, dimensions, and constants
