Answer:
Acceleration
Explanation: Force is how much one thing is being applied so it is not that and inertia is something sitting still so therefore using process of elimination, it is acceleration.
Compounds Na₂SO₄ and NaCl are mixed together are we are asked to find the concentration of Na⁺ in the mixture
Na₂SO₄ ---> 2 Na⁺ + SO₄³⁻
1 mol of Na₂SO₄ gives out 2 mol of Na⁺ ions
the number of Na₂SO₄ moles added - 0.800 M/1000 * 100 ml
= 0.08 mol
therefore number of Na⁺ ions from Na₂SO₄ = 0.08 * 2 = 0.16 mol
NaCl ----> Na⁺ + Cl⁻
1 mol of NaCl gives 1 mol of Na⁺ ions
number of NaCl moles added = 1.20 M/1000 * 200 ml
= 0.24 mol
number of Na⁺ ions from NaCl = 0.24 mol
total number of Na⁺ ions in the mixture = 0.16 mol + 0.24 mol = 0.4 mol
as stated the volumes are additive,
therefore total volume = 100 ml + 200 ml = 300 ml
the concentration of Na⁺ ions = number of moles / volume
= 0.4 mol/ 0.3 dm³
concentration of Na⁺ = 1.33 mol/dm³

Seismic waves
Explanation:
Seismic waves are disturbances that transmits energy elastically and let's scientist have a glimpse of the interior of the earth.
These waves can pass through any component layer of the earth due to their unique properties.
There are four types of seismic waves but the two body waves are the most important in studying the earth's interior.
- Seismic p-waves can pass through any earth materials as they are longitudinal waves.
- Seismic s-waves are shear waves and can only pass through solids. liquids and gases cannot be sheared.
