Density is a property of an object or substance that can be described through the correlation of the mass of an object over its volume.
Mathematically, density = mass / volume.
In description, the relationship of density and mass is positively correlated and with volume, inversely.
Since density and mass is positively correlated then if you increase the mass, the density of the object will also increase leaving density and volume the same.
Example:
Mass = 10 g changes to 20
Volume = 5 cm3
Density =?
1. D = m / v
2. D = 10 g / 5 cm3
3. D = 2 g / cm3
4. D = 20 g / 5 cm3
5. D = 4g/cm3
Answer:
d. less than the total current in the circuit
b. force, distance, time
The equation for Work = Force * Distance
The equation for Power = Work / Time = Force * Distance / Time
Answer:
8.33 meters/sec.
Explanation:
distance = 250 meters
time = 30 sec.
velocity = distance / time
= 250 meters
30 sec.
= 8.33 meters/sec.
