Essential Knowledge
It is essential that the student be able to distinguish between specialized structures that allow protists and fungi to obtain energy and explore their environment.
Protists
Protists are organisms that are classified into the Kingdom Protista. Although there is a lot of variety within the protists, they do share some common characteristics.
● Protists are usually single celled organisms.
● Live in moist environments.
● Vary in the ways they move and obtain energy.
Protists obtain their energy in several ways.
● Animal-like protists ingest or absorb food after capturing or trapping it.
● Plant-like protists produce food through photosynthesis.
● Fungus-like protists obtain their food by external digestion either as decomposers or as parasites.
● Some protists have both autotrophic and heterotrophic characteristi
Answer:
El peso de la persona B es la mitad del peso de la persona A.
Explanation:
El peso de la persona B puede calcularse con la siguiente ecuación:
(1)
En donde:
: es la masa de la persona B
g: es la gravedad
Dado que la persona B tiene la mitad de la masa de la persona A, tenemos:
(2)
En donde:
: es la masa de la persona A
Al introducir la ecuación (2) en (1) nos queda:
(3)
Sabemos que el peso de la persona A está dado por:
(4)
Entonces, al introducir la ecuación (4) en (3) tenemos:
Por lo tanto, el peso de la persona B es la mitad del peso de la persona A.

Apply the law of conservation of momentum for this situation. The law states that the momentum of a system is constant (in absence of external forces acting on it).
The 'system' in this case are the two skaters. There is no external force on the skaters. Suppose the skaters are initially standing still. The momentum in the system is 0. This value will need to remain constant, even after the mutual push (which is a set of forces from <em>inside</em> the system). So we know that
(total momentum before) = (total momentum after)
Indexing the masses and velocities by the first letter of the skaters' names:

From the last row, you can see that the skaters will have momentum of same magnitude but opposite direction, after the push off. That answers the first question: neither will have a greater momentum (both will have one of same magnitude).
Since Ricardo is heavier, from the above equality it follows that

In words, Paula has the greater speed, after the push-off.
