50 POINTS AND BRAINLEST A) In order for the bug to fly through the air, a force has to push the bug forward. Identify this force.

B) Explain how the bug is able to fly using Newton’s 3rd Law of Motion? (Hint: Think back to how a swimmer moves through the water.)

The bug was at rest on a tree when it saw the car and decided to fly toward it. If the bug has a mass of 0.05 kg and accelerates at 2 m/s2 , what’s the net force on the bug? SHOW YOUR WORK!!! Remember your units.

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.

Considering only the earth's rotation, determine how much later the asteroid would have had to arrive to put the explosion above helsinki at longitude 25˚ e? this would have obliterated the city.

Explain what will happen if decomposers were apsent from a forest ecoysystem.
