Answer:

a = 3.776\,\frac{m}{s^{2}} (hacia arriba).

Explanation:

La dirección y magnitud de la aceleración se determina a partir de la siguiente ecuación de equilibrio:

\Sigma F = T - m\cdot g = m\cdot a

La expresión de la aceleración es:

a = \frac{T}{m} - g

a = \frac{163\,N}{12\,kg}-9.807\,\frac{m}{s^{2}}

a = 3.776\,\frac{m}{s^{2}}

La cubeta es acelerada hacia arriba.

Heavier elements require higher temperatures to fuse. After stars run out of hydrogen in their cores, they leave the main sequen
Kruka [31]

Answer:

A. Add mass to the Sun.

Explanation:

A. Add mass to the Sun.

Adding mass will make to take more time for the hydrogen to run out and hence, enough temperature will be developed to fuse helium atom into other heavier elements, and eventually get hot enough to fuse the helium in their cores into carbon.

The only hypothetical solution is that we need to add Mass to the Sun.

A force AB of length 100m and weight 600N has its centre of gravity 4.0 m from the end, and lies on horizontal ground calculate
Stells [14]

Answer:

F = 24 N

Explanation:

In this exercise we have a bar l = 100 m with a center of gravity x = 4 m, which force is needed to lift it from the other end

Let's use the rotational equilibrium relationship, where we consider the counterclockwise rotations as positive and fix the reference system at the point closest to the center of gravity

           ∑ τ = 0

           F l -x W = 0

           F = \frac{x}{l} \  W

let's calculate

          F = \frac{4}{100}4/100 600

          F = 24 N
