Answer:
the force acting on Jennifer is 180 N
Explanation:
The computation of the force acting on Jennifer is shown below:
As we know that
Force = mass × acceleration
= 60 kg × 3 m/s
= 180 N
hence, the force acting on Jennifer is 180 N
We simply applied the above formula
Na₂CO₃(s) → 2Na⁺(aq) + CO₃²⁻(aq)
The sodium carbonate formed from a strong base and a weak acid. Hydrolysis is subjected to the anion of a weak acid.
CO₃²⁻ + H₂O ⇄ HCO₃⁻ + OH⁻
HCO₃⁻ + H₂O ⇄ H₂CO₃ + OH⁻
pH>7 alkaline solution
2Na⁺ + CO₃²⁻ + 2H₂O ⇄ 2Na⁺ + 2OH⁻ + H₂CO₃
The atomic number is the number of Protons on the nucleus of the atom, whereas the mass number of some isotope is the mass of the protons plus the mass of the neutrons. That's the difference between isotopes: number of neutrons.

I'm pretty sure the answer is Pyroclastic flow
The lowest point of a wave is called trough.
