What mass will a pumpkin have a force of 450 newton’s accelerates it to 110 m/s^2? include the correct units.

Plz dont type in wrong or just say something to get all my ponit if you do thing willl happen > : l in an environment can destroy entire ecosystems. these changes can occur quickly or over time. which environmental change occurs fastest? volcanic eruption regrowth of forest after volcanic eruption pond succession decomposition of a treeover time the trees in african have increased in length. many species have had to adapt to this change in order to survive. which of the following is a structural adaptation that has the african giraffe meet this change? question 11 options: the african giraffe has become a faster at running from its predators. the african giraffe's neck has increased in size over the years. the african giraffe have moved to another part of africa. the african giraffe has not adapted and struggles to survive. eve and sammy are discussing the affects of farming on the environment. eve states that farming does not harm our environment. she believes that it is only beneficial for the ecosystem and species living in it. sammy states that farming can have major impacts on the environment. he believes farming can cause habitat loss. who is correct? question 12 options: eve is correct because farming only leads to positive affects on ecosystems. sammy is correct because farming has major affects on the environment including soil erosion and flooding. eve is correct because farming does not lead to soil erosion and flooding. neither of them are correct. a power plant recently purchased land and will be building a large factory on wetlands in florida. which of these is not an environmental effect of destroying these wetlands? question 13 options: destroying the wetlands will create a loss of habitat for many species. destroying the wetlands will create flooding. destroying the wetlands will create species to relocate to a new area. destroying the wetlands will change the climate in this area.ever since non-native mussels were introduced into the great lakes, they have caused ecological problems. mussels are very efficient filter feeders. they are better at filtering algae from the water than native species are. which of the following would not result from mussel introduction? question 14 options: excessive growth of mussel populations decline in populations of native mussel species water becoming clearer because mussels eat more algae excessive growth of algae that kills other organismswhat would be an immediate effect of the construction of roads and parking lots on the transfer of energy from producers to consumers in an ecosystem? question 15 options: a decrease in the number of producers a decrease in the number of consumers an increase in the number of producers an increase in the number of consumers

Red’s momentum vector before the collision is green’s momentum vector after the collision. question 1 options: shorter than longer than equal to question 2 (1 point) saved since green bounces off red, this must be an collision. question 2 options: explosion inelastic elastic question 3 (1 point) saved red transfers of its momentum to green during the collision. question 3 options: little all most none question 4 (4 points) why does red transfer all its momentum to green? back up your answer with information from the simulation. write at least 2 sentences. question 4 options: skip toolbars for . more insert actions. more text actions. more paragraph style actions. question 5 (1 point) now make red much heavier than green. answer the questions below to describe how both red and green behave after the collision. you might want to play the sim multiple times. click on restart or return balls to start over. to see numbers, check the show values box (inside the green box). red during the collision because it transferred some momentum to green. question 5 options: sped up kept the same velocity slowed down question 6 (1 point) green sped up during the collision as it question 6 options: lost momentum to red maintained a constant momentum. gained momentum from red question 7 (1 point) after the collision . . question 7 options: red bounced off green and went to the left. green moved to the right. both green and red stopped as they have lost all momentum. red stopped and green moved to the right. both green and red moved to the right. question 8 (4 points) only some of red’s momentum was transferred to green. why did this occur? back up your answer with information from the simulation. write at least 2 sentences. question 8 options: skip toolbars for . more insert actions. more text actions. more paragraph style actions. question 9 (1 point) now make red much lighter than green. answer the questions below to describe how both red and green behave after the collision. you might want to play the sim multiple times. click on restart or return balls to start over. to see numbers, check the show values box (inside the green box). which is true about the collision? question 9 options: green slowed down after the collision therefore it must have lost momentum. green sped up after the collision therefore it must have lost momentum. green sped up after the collision therefore it must have gained momentum. green slowed down after the collision therefore it must have gained momentum. question 10 (1 point) since green gained momentum, red had to have momentum because you cannot create or destroy momentum. question 10 options: lost kept the same amount of gained question 11 (1 point) since green was so much and harder to move, it caused red to bounce back to the left giving red . question 11 options: lighter. . . . negative heavier . . . . negative lighter. . . . positive heavier . . . . positive question 12 (4 points) now, click on more data at the bottom of the sim. play with different numbers for the masses and starting velocities. you can even make the starting velocities negative! tell me one thing you discovered by adjusting the speeds and masses. write at least 2 sentences. be specific and use words like velocity, momentum, mass, increased, decreased, etc. question 12 options: skip toolbars for . more insert actions. more text actions. more paragraph style actions. part 2: inelastic collisions question 13 (1 point) click on the "less data" box at the bottom of the sim. in the green box, slide the elasticity meter all the way to inelastic so there is 0% elasticity: make the masses whatever size suits you. make sure that green starts out with a velocity of 0 m/s – if you didn’t change this in the last step, you don’t need to do anything. push play and observe! true or false: when red and green collide, they stick together. question 13 options: true false question 14 (1 point) the velocity of red & green after the collision is the velocity that red started off with. question 14 options: larger than smaller than equal to
