What's the momentum of a 3.5-kg boulder rolling downhill at 5 m/s? A. 17.5 km·m/s B. 70 kg·m/s C. 8.5 kg·m/s D. 14.3 kg·m/s
2 answers:
Answer : The correct option is, (A)
Solution : Given,
Mass of an object = 3.5 Kg
Velocity of an object = 5 m/s
Momentum : Momentum is equal to the product of mass of an object and the velocity of an object.
Formula used :
where,
p = momentum of an object
m = mass of an object
v = velocity of an object
Now put all the given values in this formula, we get the value of momentum of an object.
Therefore, the momentum of an object is,

Answer: Crystallization is a technique which chemists use to purify solid compounds. Crystals often form in nature when liquids cool and start to harden. Certain molecules in the liquid gather together as they attempt to become stable. They do this in a uniform and repeating pattern that forms the crystal. The process is based on the principles of solubility: compounds (solutes) tend to be more soluble in hot liquids (solvents) than they are in cold liquids. If a saturated hot solution is allowed to <u>cool</u>, the solute is no longer soluble in the solvent and forms crystals of pure compound. Impurities are excluded from the growing crystals and the pure solid crystals can be separated from the dissolved impurities by filtration.
For an example the salt we get from seawater can have many impurities in it. Hence, the process of crystallization is in use to remove these impurities.
