Properties of Salt
Crystals or white crystalline powder.
Transparent and colourless in crystalline form – rather like ice.
Crystallises in the isometric system, usually in the form of cubes.
Soluble in water (35.6g/100g at 0°C and 39.2g/100g at 100°).
Slightly soluble in alcohol, but insoluble in concentrated hydrochloric acid.

Answer:
21.932 kN
Explanation:
Given:
Angular velocity, ω = 1.00 × 10⁵ rev/min
Diameter of the turning rotor = 20.0 cm = 0.2 m
or
Radius, r = = 0.1 m
Mass of the sample = 2.00 g = 0.002 Kg
Now,
Force = mass × ω² × r
Here,
ω = 100000 rev/min
or
ω = rev/sec
or
ω = 1667.67 rev/sec
also,
ω = 1667.67 × 2π = 10471.97 radian/s
Therefore,
force = 0.002 × 10471.97 × 0.1
or
Force = 21932.43 N
or
Force = 21.932 kN
b) No the force would not be different as it does not depend on the axis of rotation as it can be observed in the formula
Force = mass × ω² × r

Answer:
c
Explanation:
Deforestation is a particular concern in tropical rain forests because these forests are home to much of the world's biodiversity. For example, in the Amazon around 17% of the forest has been lost in the last 50 years, mostly due to forest conversion for cattle ranching.
