Answer : chemical reaction
Mixing an acid with a base is a common chemical reaction.
Explanation:
Because There are 6.022x10^23 atoms per mole; therefore, (6.022x10^23×3)=18.066x10^23 atoms of titanium.
When we can get the Kinetic energy from this formula KE= 1/2 M V^2
and we can get the potential energy from this formula PE = M g H
we can set that the kinetic energy at the bottom of the fall equals the potential energy at the top so,
KE = PE
1/2 MV^2 = M g H
1/2 V^2 = g H
when V is the velocity, g is an acceleration of gravitational force and H is the height of the fall.
∴ v^2 = 2 * 9.8 * 8 = 156.8
∴ v= √156.8 = 12.5 m/s
