Longitudinal, because the sound can only travel at one direction
Molecules in the solid phase have the least amount of energy, while gas particles have the greatest amount of energy.
Scott needs to determine the density of a metallic rod. First, he should determine the mass of his sample on the laboratory balance. Second, he should measure the volume of his sample by water displacement. Finally, he can calculate the density by dividing mass/volume.
Hope this helped ;)
Answer:
a=4,32m/s^2
Explanation:
Fnet = F1 - F2
= 12-1.2
= 10.8N
m=2.5kg
Fnet =ma
10.8=2.5a then divide both sides by 2.5 to get acceleration
Acceleration = vf-vi /t
10-22/3=2.6m/s^2
