The main ring of the tevatron proton-antiproton collider at fermilab has a maximum beam energy of 1 tev. when it collides protons onto counter circulating antiprotons of the same beam energy, the center-of-mass energy vs 2 tev. if instead the tevatron collides antiprotons onto protons at rest, vs 43 gev, which is significantly less [3 points] what would the beam energy need to be for the fixed target collisions to reach the same center-of-mass energy as the symmetric tevatron collider? a. b. 3 points] what is the minimum proton beam energy required in order to produce an extra proton-antiproton pair in a fixed target collision with another proton?

Use the library or internet to research each planet. make a chart comparing the following: approximate surface temperature relative surface gravity compared to earth atmospheric gases water in any form: solid, gas, or liquid when you have completed your chart, use the information you have collected to answer the following questions: which is the hottest planet? which is the coldest planet? which planet's temperature is closest to that of earth? (note: water boils at 100°c/212°f. water freezes at 0°c/32°f) which planet has the greatest gravitational attraction? which planet has the least gravitational attraction? which planet's gravitational pull is closest to that of earth? do any of the planets have oxygen in their atmosphere? which planet's atmosphere most resembles that of earth? do any of the planets have flowing water? which planet's water resources (solid, gas, or liquid) might be close to the amount on earth? which planet most resembles earth in terms of all of the factors: temperature, gravity, atmosphere, and water? if earth became an uninhabitable planet, which planet do you think would be the next best to live on? explain your answer.
