1) The particle moves along the positive X-axis, hence its velocity varies as V=α√𝑥, where α is
a positive constant. Assuming that at the moment t=0 the particle was located at the point
х=0, please find:
a) how does velocity and acceleration of the particle depend on time / (time dependence
of velocity and acceleration of the particle);
b) the average velocity of the particle during the time it runs the first S meters along its path.
2) A thin half-ring with the radius of R=20cm is uniformly charged with the charge of q=0,7
nC. Find the magnitude of the electric field strength at the center of curvature of this halfring.
3) For this 275-word assignment, you will write a summary of a mission to a terrestrial world
that has happened since 2000. To do this, you will need to do a little bit of research about a
