Answer:Stirring.
Explanation:Stirring a solute into a solvent speeds up the rate of dissolving because it helps distribute the solute particles throughout the solvent. For example, when you add sugar to iced tea and then stir the tea, the sugar will dissolve faster.
Answer:
ω = 5.41 rad/s
Explanation:
Since the rod is rotating around its axis, angular momentum will play part in this question.
The conservation of angular momentum implies that

So, the initial angular momentum is

The final angular momentum includes the rod and the bullet together. So,

Hello there!
The formula for sodium sulfide is Na2S.
Hope this helps!
Answer:
45.09 m/s^2
Explanation:
from the question we were given the following parameters
mass = 931.9 kg
initial velocity (V1) = 0 m/s ( since it started from rest )
final velocity (V2) = 25.7 m/s
time (t) = 0.57 s
The average acceleration is given by:
a = ( V2 - V1 ) / t
therefore
a = (25.7 - 0) / 0.57 = 45.09 m/s^2
