True because in a solid particles dont move so it wouldn't be in a constant motion.
Answer:
Actual yield = 20.03g
Explanation:
% 
= 
Actual yield = % yield.(theoretical yield) / 100
Actual yield = 75.26.7/100
Actual yield = 20.025
For the answer to the question above, <span>ater weights 1000kg per meter cubed. the volume of the pool is part A is 5*4*3 = 60 meters cubed </span>
<span>60*1000 = 60 000kg. the force from this is m*g = 60 000 * 9.81 = 588kN </span>
<span>part B: </span>
<span>volume: 4*4*3 = 48 meters cubed </span>
<span>48 * 1000 = 48000kg </span>
<span>F = 9.81*48000 = 470kN
I hope this helps.</span>
