Factors affecting energy transfer Lesson 2.14-2.15

Question 9 options:

Larger waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.

SMALLER waves have extra spaces and areas to trap air, increasing the transfer of the wind's energy to the water.

Wind moving over a relatively flat water surface has less area to come in contact with the water, and this reduces energy transfer.

Wind moving over a relatively flat water surface has GREATER area to come in contact with the water, and this INCREASES energy transfer.

The roller coaster from problem #1 then tops a second hill at 15.0 m/s, how high is the second hill? 91.5 m 79.2 m 80.0 m 68.5 m

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
