Using the map and the minimal knowledge that Liz has at this point, propose three different hypotheses regarding the sudden high mortality of marine iguanas and post them to this discussion board. 2. Read through other students’ hypotheses, choose the hypothesis that seems most likely to you and determine what evidence you would need to support (or refute) it. You will include this information in your activity worksheet.

Light from a sodium lamp passes through a diffraction grating that has 1000 slits per millimeter. the interference pattern is viewed on a screen 1.000 m behind the grating. the first (m = 1) two bright yellow fringes that are visible are 0.7288 m and 0.7300 m from the central maximum. what are the wavelengths of these two fringes?

Which statement is true? a) the work done to lift an object 6 meters is greater than the gravitational potential energy it gains. b) the work required to push an object is less than the work required to pull an object the same distance. c) the work required to raise an object to a height is equal to the gravitational potential energy the object gains. d) the work done against gravity to lift an object straight up is greater than the work required to roll it up a ramp.
