Can someone please please help me It is crash-test-dummy Ed's first day on the job. He (and his 50-kg mass) gets to try out the new 1,200-kg Porsche 911. Lucky Ed! He has to drive it into a brick wall. Unlucky Ed! But it's his job, so he does it.
The Porsche and Ed are moving 30 m/s when they collide with the wall, with an impulse time of 0.5 s.
1. What is the magnitude of their initial momentum? (4 points)
2. What is the magnitude of their final momentum? (3 points)
3. What is the magnitude of the impulse of the collision? (3 points)

please don't answer with a weird link, thanks

hello! if you would like i could share a research essay i did a month or two ago!

answer:

the water molecules are transferred from the roots to the stem or top parts of the tall tree because of important properties of water which are adhesion, cohesion and capillary action. cohesion is the property of water molecules keeps water molecules in a combined state by sharing of bonds between them at the atomic level. adhesion allows the interaction of water molecules with other substances or substrate. adhesion will cause the attachment of water molecules to the wall of the vessel (xylem) of the plant. capillary action occurs when the adhesive force to the vessel wall is stronger than the cohesive force between water molecules. capillary action mimics the transfer of water from a tube or pipe. in this way water utilizes its property to transfer water from down to top level of the plant.  

for example, no new evidence will demonstrate that the earth does not orbit around the sun (heliocentric theory), or that living things are not made of cells (cell theory), that matter is not composed of atoms, or that the surface of the earth is not divided into solid plates that have moved over geological timescales .
