What occurs when air moves from an area of high pressure to an area of lower pressure

How is the gravitational force related to the distance between two objects?

Ihave a density of 1.61g/cm^3 and a mass of 28g. find the missing value

Aparticle initially located at the origin has an acceleration of = 2.00ĵ m/s2 and an initial velocity of i = 8.00î m/s. find (a) the vector position of the particle at any time t (where t is measured in seconds), (b) the velocity of the particle at any time t, (c) the position of the particle at t = 7.00 s, and (d) the speed of the particle at t = 7.00
