Physics and Natural Sciences Questions -

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 x=0, please find:

a) How does velocity and acceleration of the particle depend on time / (time dependence of velocity and acceleration of the particle?)

The average velocity of the particle during the time it runs the first S meters along its path.

2. Gas tank of the volume V is exhausted with the axial piston pump. It pumps ΔV of volume per one working cycle. After how many cycles does the pressure in the gas tank reduce by K times? Assume this is an isothermal process and a perfect gas.

3. 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 half-ring.
