Volume = 30*30*30 = 27000 cm^3
density = 2.8 g/cm^3
mass = 27000*2.8 = 75600g = 75.6 kg
Force = mass*acceleration.
Therefore, a force has a magnitude and direction.
Answer:
Total: 200 meters, Displacement: 100 meters South
Explanation:
First, add up the meters traveled to get the total distance.
50m + 150m = 200m
Lastly, displacement is the shortest distance from the initial position to the final position. The person first walked 50 meters north but then traveled 150 meters south. Therefore, their displacement was 100 meters south.
50m - 150m = -100m
(Note: Directions are vectors. North and East are positive vectors while South and West are negative)
Particles stay the same unless there is a chemical change whether the matter is solid, liquid or gas. ... When substances change state there is no change in mass so if 100 g of ice is melted 100g of water are formed this will boil to form 100g of steam (this is called "conservation of mass").
Answer:
That something is called having a high viscosity.
Explanation:
The measure expressing a "resistance to flow" is called viscosity. Viscosity relates to internal friction forces in a fluid causing it to flow with more or less difficulty. Highly viscous stuff is perceived "thick" or "sticky."
