Los hermanos Ana Victoria y José Leonardo están patinando en el hielo, con 25 y 20 kg respectivamente de masa, si Victoria empuj
andreyandreev [35.5K]

Utiliando las leyes de Newton encontraremos que la aceleración de Ana es -1.6 m/s^2.

La segunda ley de Newton dice que:

F = m*a

Fuerza es igual a masa por aceleración.

La tercera ley de Newton dice que cuando dos objetos interactuan, cadan objeto ejerce una fuerza de <u>igual magnitud pero opuesta direccion</u> en el otro.

Ahora veamos como aplicar esto.

Sabemos que la niña empuja al niño, asumamos que con una fuerza F.

Tendremos entonces la ecuación:

F = 20kg*(2m/s^2) = 40N

Y por la tercer ley de Newton, esta misma fuerza (pero en opuesta dirección) se aplica a la niña, entonces tendremos:

-40N = 25kg*a

-40N/25kg = a = -1.6 m/s²

La aceleración con la que retrosede la niña es -1.6 m/s²

Select all the species that are ions.<br><br> HCl<br> NaCl<br> NH4+<br> H2PO4-<br> CCl4<br> H3O+
nata0808 [166]

Answer:

NH₄⁺

H₂PO₄⁻

H₃O⁺

Explanation:

  • An ion is an atom or molecule with a net electric charge due to the loss or gain of one or more electrons.
  • Ion may be positively charged "cation" or negatively charged "anion".
  • Neutral molecule has a net charge of zero.

<em>So, the species that are ions are: </em>

NH₄⁺

H₂PO₄⁻

H₃O⁺

If two identical atoms are bonded together, what kind of molecule is formed?
AlekseyPX

Answer:

C. A linear, nonpolar molecule

Explanation:

Molecules which are alike usually have the same degree of pull which results in them sharing electrons. This sharing of electrons is known as the molecules exhibiting Covalent bonding between them.

The equal pull also results in the cancelling out of electrons and favoring non polar bonds due to the absence of free electrons which would have been able to interact with H2O in a polar binding system.
