The density of an object is defined as its mass divided by its volume. suppose the mass and volume of a rock are measured to be 8 g and 2.8325 cm3.

2824.36011 kg/m³

Explanation:

The missing statement is: determine the rocks density in kg/m³

- Data

mass of the rock, m = 8 g

volume of the rock, V = 2.8325 cm³

- Unit conversions

1000 g are equivalent to 1 kg, then 8 g are equivalent to:

1000 g / 8 g = 1 kg / x kg

x = 8/1000 = 0.008 kg

1,000,000 cm³ are equivalent to 1 m³, then 2.8325 cm³ are equivalent to:

1,000,000 cm³ / 2.8325 cm³ = 1 m³ / x m³

x = 2.8325/1,000,000 = 0.0000028325 m³

- Density calculation

Density = m/V

Density = 0.008/0.0000028325

Density = 2824.36011 kg/m³

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.

hi,

what occurs during a solar eclipse?

there are small tides across earth.

the moon is between earth and the sun.

p.s. im not sure if the first answer is correct because during a solar ecliphse there are spring tides and i dont know if they are the same.
