Answer:
The correct answer is - 0 m/s.
Explanation:
In this position-time graph or distance-time graph, there are three different part that shows three different velocities one in increasing as it moves from a lower position in relative to time and one is stationary and the third is decreasing.
'Straight lines' on a distance-time graph suggest that the movement of the object is constant. During 'Part B' of the journey the object travels 0m in 3s. It is stationary for 3 seconds so the velocity will be zero as well.
Answer:
Carbon dioxide (CO2) and water (H2O)
Easy:
1. 2K + Br2 — KBr
2. 4Sb + 3O2 — SB4 O6
Medium:
1. 2Na+2H2O — 2NaOH+H2
2. 2KNO3 — 3KNO2+O2
Hard:
1. 4NH3+5O2 — 4NO+6H2O
2. C2H5OH+3O2 — 2CO2+3H2O
Answer:
Diffusion is the movement of molecules from an area of high concentration of the molecules to an area with a lower concentration. For cell transport, diffusion is the movement of small molecules across the cell membrane. ... The kinetic energy of the molecules results in random motion, causing diffusion.
U really didn’t put any choices so idk
