Answer:

b. 0.6m/s, 0.7m/s, 0.61m/s, 0.62m/s

Explanation:

Precision of a measurement is the closeness of the experimental values to one another. Hence, experimental measurements are said to be precise if they are close to each other irrespective of how close they are to the accepted value. Precision can be determined by finding the range of each experimental value. The measurement with the LOWEST RANGE represents the MOST PRECISE.

Note: Range is the highest value - lowest value

Set A: 1.5 - 0.8 = 0.7

Set B: 0.7 - 0.6 = 0.1

Set C: 2.4 - 2.0 = 0.4

Set D: 3.1 - 2.9 = 0.2

Set B has the lowest range (0.1), hence, represent the most precise value.

What evidence would you observe if the law of conservation of mass is obeyed when mixing two solutions?​
Marianna [84]

Answer:

You should have noticed that the number of atoms in the reactants is the same as the number of atoms in the product. The number of atoms is conserved during the reaction. However, you will also see that the number of molecules in the reactants and products are not the same.

Irina-Kira [14]

Answer:

Explanation:

a = Δv/Δt = (v₁ - v₀) / (t₁ - t₀)

A a = (10 - 0) / (5 - 0) = 2 m/s²

B a = (10 - 10) / (15 - 5) = 0 m/s²

C a = (5 - 10) / (25 - 15) = - 0.5 m/s²
