Answer:
2. The density, of a substance is its mass per unit volume. The symbol most often used for density is ρ, although the Latin letter D can also be used. Mathematically, density is defined as mass divided by volume: {\displaystyle \rho ={\frac {m}{V}}} where ρ is the density, m is the mass, and V is the volume.
3. The SI unit of speed is m/s and the CGS is cm/s.
1m/s = 100cm/s
4. The density of water can also be affected by temperature. When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume. The warmer the water, the more space it takes up, and the lower its density. When comparing two samples of water with the same salinity, or mass, the water sample with the higher temperature will have a greater volume, and it will therefore be less dense.
5. Measuring jar, scale, vernier calipers are used to measure the volume of an object.

7. 1000cm³
8. 54km/h = 15m/s
9. 18m/s = 64.8km/hr
10. 36m/s = 2160m/min
