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?

The charge on an electron is 1.60218 × 10−19 c and its mass is 9.10939 × 10−31 kg. how strong a magnetic field must be experienced by the electron if its path is a circle of radius 5.5 cm? answer in units of t.

The electric potential a distance r from a small charge is proportional to what power of the distance from the charge? a. r^-1 b. r c. r^-2 d. r^2

The chart shows the costs and shipping times for materials that a company needs to build a new product. which describes the best trade-off if the company needs to start building their product within the next two years? they should order the domestic materials because it is always best to choose the fastest shipping time. they should order the imported materials because it is always best to choose the lowest cost for materials. since the shipping time is longer, they should order the domestic materials because the additional cost is worth it to get the materials in time. even though the shipping time is longer, they should order the imported materials because they are less expensive and should arrive in plenty of time to build the product.
