En la siguiente expresión matemáticas w=mg el peso w con relación a se relaciona con la masa m en una proporción
1 answer:
Answer:
a) Directamente proporcional
Explanation:
El peso se puede definir como la fuerza que actúa sobre un cuerpo o un objeto como resultado de la gravedad.
Matemáticamente, el peso de un objeto viene dado por la fórmula;
Donde;
m es la masa del objeto.
g es la aceleración debida a la gravedad.
De la expresión matemática, podemos deducir que el valor del peso de un objeto es directamente proporcional a la masa del objeto.
Por lo tanto, un aumento en la masa de un objeto provocaría un aumento en el peso del objeto y viceversa.

The force balance of the system is given by
The spring constant for that spring is .
Answer:
Approximately .
Explanation:
The change in the gravitational potential energy of the pendulum is directly related to the change in its height.
Refer to the sketch attached. The pendulum is initially at . Its highest point is at
. The length of segment
gives the change in its height.
The lengths of and
are simply the length of the string,
. To find the length of
, start by calculating the length of
.
forms a leg in the right triangle
. Besides, it is adjacent to the
angle
. Its length would be:
.
The length of would thus be
.
The change in gravitational potential energy can be found with the equation
. In this equation,
is the mass of the object,
near the surface of the earth, and
is the change in the object's height.
In this case, and
. Therefore:
.
