Angioplasty is also called percutaneous coronary intervention (PCI). For angioplasty, a long, thin tube (catheter) is put into a blood vessel and guided to the blocked coronary artery. The catheter has a tiny balloon at its tip.

Que moralidad hay en una disolución de 35g de KCI diluidos en 250ml de agua
fredd [130]

Responder:

<h2>1.892mol / L </h2>

Explicación:

La molaridad se define como la relación del mol de una solución por litro de su solución.

Molaridad = Mole de soluto / solución (en litros)

La solución aquí es agua = 250 ml =  0.25L

El soluto es cloruro de potasio (KCl)

Para obtener el mol del soluto, usaremos la fórmula;

Mole del soluto = Masa de KCl / Masa molar de KCl

Masa dada de KCl = 35 g

Para la masa molar de KCl donde K = 39 g / mol y Cl = 35 g / mol

Masa molar de KCl = 39 + 35 = 74 g / mol

Mole del soluto = 35/74 = 0.473 mol

Molaridad = 0.473mol / 0.25L

Molaridad en la solución = 1.892mol / L

En que punto tendra mayor energua potencial y en que pu to tendra mayor enerdia cinetica​
netineya [11]
A
.
La energía cinética se define como:
⇒
mi
k
=
1
2 metro v2
Dado que la masa del péndulo no cambiará, la única forma de que cambie la energía cinética es que cambie la velocidad del péndulo. La energía cinética es máxima cuando la velocidad es máxima. Esto ocurre en la parte inferior del péndulo.
B
.
Si la energía cinética es más alta en la parte inferior del péndulo, entonces es donde la energía potencial es la más baja. Entonces, la energía potencial sería más alta cuando el péndulo esté en su punto más alto a cada lado de su movimiento donde está estacionario por un instante. Este es el punto donde toda la energía cinética se ha convertido en energía potencial (
mi
k
=
0
desde
v
=
0
).
