The average kinetic energy of the molecules that make up the solution also increases with increasing temperature. This increase in kinetic energy allows the solvent molecules to more effectively break apart the solute molecules that are held together by intermolecular attractions. </span></span></span></span>
It can't. Waves must have a medium to travel through
<h3><u>Answer;</u></h3>
B. 16.2 m/s
<h3><u>Explanation</u>;</h3>
Using the equation;
v = u + at; where v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken;
u = 21 m/s, a= -2.4 m/s^2 and t = 2 seconds
Therefore;
v = 21 + ((-2.4) × 2)
= 21 - 4.8
<u> = 16.2 m/s</u>
4.7km^2 * (1000m)^2
————
1km^2
(1000000m^2)
4.7km^2 * ———————
1 km^2
(4.7km^2)(1000000m^2)
————————————
(1km^2)
(4.7)(1000000m^2)
= 4700000 m^2
= 4.7 x 10^6 m^2
