Anhydrous salts absorb moisture from their surroundings when it gets cooled, hence the mass of the content would increase. It can be prevented if we allow the evaporating dish to cool in a dessicator. A dessicator is a glass or plastic container in which chemicals can be stored and allowed to cool. This container can be sealed. Dessicator would provide an environment free of moisture instead of keeping in atmospheric air having moisture content.
Answer:
v = 22.68 10⁻³ m / s
vₓ = 5.32 10⁻³ m / s
, v_{y} = 22.08 10⁻³ m / s
Explanation:
Velocity is defined by
v = Δs / Δt
let's calculate for each axis
X axis
vₓ = (3.07 - 1.33) / 327
vₓ = 5.32 10⁻³ m / s
Y axis
= (4.33 - (- 2.89)) / 327
v_{y} = 22.08 10⁻³ m / s
the magnitude of the velocity can be calculated using the Pythagoras theorem
v² = vₓ² + v_{y}²
v = √ (vₓ² + v_{y}²)
v = √ (5.32² + 22.05²) 10⁻³
v = 22.68 10⁻³ m / s
