The following question is lowing question, include units. optional! to receive full credit for the fol you muust show your work and your final answer must 5. (10 points (bonus)) the source of the sun's energy is a sequence of nuclear re- occur in its core. the first of these reactions involves the collision actions that or to protons, which fase together to form a single mucles that weighs les than the e two separate protons thus releasing energy. for this "nuclear fusion" process to occur, the two protons must first approach until their surfaces are essentially touching. (a) (6 points) assume both protons are moving with the same speod and they collide head-on. the radius of a proton is approximately 1.2 x io-s m, use thi is to estimate the minimum speed that will allow fusion to occur. (b) (4 points) you may recall from thermodynamics that the average trans- energy of a particle in a gas at temperature t is jkbt lational kinetic where kp is the boltzmann constant 1.4 x 10-23 j/k. what is the mini- mum temperature of a star where the proton-proton nuclear fusion above is occurring?

be subject to a force andchange its motion

it is a negative acceleration

russian is not my first language, so i'm afraid i can't write out an answer in russian, but hopefully you can find a way to do so. here's my best translation of the problem: you're given a plot of a particle's position in one-dimensional space over time, and you're asked to find either the total distance traveled by the particle after 6 seconds had elapsed, or the total displacement of the particle after 6 seconds.

if you want the total distance traveled, you would first need to determine the particle's velocity as a function of time, then integrate that over the 6-second interval. we know the position function is quadratic with roots at 0 and 6, so we have

where is unknown. because the position is parabolic, there is symmetry about the midpoint at , and we know that

so that the position function is

which means the velocity is

then the total distance traveled is

so the total distance traveled is 20 m.

on the other hand, if you want to find displacement: the particle starts at and ends at , so its displacement is 0.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it
