Answer:

The correct option is the last option.

Explanation:

Generally, when trying to create a mechanical advantage of a lever for an apparatus or a machine, <u>the load is usually moved closer to the fulcrum</u>. Hence, if a lever has a total length of 12 meters and the fulcrum is placed at 6 meters (the center), the best way (based on the previous statement) to double the mechanical advantage of the lever is <u>to move the fulcrum 4 meters toward the side on which the force is applied</u>. The correct option is the last option.

Calculate the density of Saturn. Show your work. How does it compare with the density of water? Explain how this can be.

stepladder [879]

Answer:

The density of Saturn is 686.81 kg/m³.

Explanation:

Mass of Saturn, $m=5.68\times 10^{26}\ kg$

Volume of Saturn, $V=8.27\times 10^{23}\ m^3$

Density of Saturn is given by its mass divided by its volume i.e.

$d=\dfrac{m}{V}$

$d=\dfrac{5.68\times 10^{26}}{8.27\times 10^{23}}$

$d=686.81\ kg/m^3$

So, the density of Saturn is 686.81 kg/m³.

The density of water is 1000 kg/m³. It is clear that the density of Saturn is less than water.

Si tomamos como referencia el recipiente uno y se aplican 5 gramos de tinta y el agua se moviera a una velocidad de 10m/s cual s

tigry1 [53]

Answer:

Kinetic energy = 0.25 J

Explanation:

The question is "If we take container one as a reference and apply 5 grams of ink and the water moves at a speed of 10m / s, what would the kinetic energy of the solution be?"

We have,

Mass of ink, m = 5 grams = 0.005 kg

Speed of water, v = 10 m/s

We need to find the kinetic energy of the solution of water and ink. Kinetic energy is associated with the motion of an object. Its formula is given by :

$K=\dfrac{1}{2}mv^2\\\\K=\dfrac{1}{2}\times 0.005\times (10)^2\\\\K=0.25\ J$

So, the kinetic energy of the solution is 0.25 Joules.
