20 points and brainliest for whoever gets it correct lara and tim took different routes to travel from point a to point c. lara took the route along a, b, and c. tim took the route along a, e, d, and c. their routes with distances and times are shown below. which person's average speed is greater? [ ] lara's, because her average speed is twice tim's average speed [ ] lara's, because her average speed is three times tim's average speed [ ] tim's, because his average speed is 0.6 miles/hour greater than lara's average speed [ ] tim's, because his average speed is 0.2 miles/hour greater than lara's average speed

Follow these directions and answer the questions. 1. set up the ripple tank as in previous investigations. 2. bend the rubber tube to form a "concave mirror" and place in the ripple tank. the water level must be below the top of the hose. 3. generate a few straight pulses with the dowel and observe the reflected waves. do the waves focus (come together) upon reflection? can you locate the place where the waves meet? 4. touch the water surface where the waves converged. what happens to the reflected wave? 5. move your finger twice that distance from the hose (2f = c of c, center of the curvature) and touch the water again. does the image (the reflected wave) appear in the same location (c of c)? you may have to experiment before you find the exact location. sometimes it is hard to visualize with the ripple tank because the waves move so quickly. likewise, it is impossible to "see" light waves because they have such small wavelengths and move at the speed of light. however, both are examples of transverse waves and behave in the same way when a parallel wave fronts hit a curved surface.

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.
