When describing the velocity of an object, you must specify the both the speed and the direction.

That’s because <em>velocity is a vector</em>: it has both magnitude (speed) and direction.

If you say that a object is travelling southwest at 70 km/s, you are giving its velocity.

If you say that it is travelling at 70 km/s, you are giving its speed.

vlada-n [284]

Answer:

6.66 mL

Explanation:

The increase in the volume is due to the addition of the iron whose volume can be calculated as:

Using,

Density = Mass / Volume

Given that:

Density of Iron = 7.87 g/cm³

Mass of iron = 52.4 g

Thus, volume is:

Volume = Mass / Density = 52.4 / 7.87 cm³ = 6.66 cm³

Also, 1 cm³ = 1 mL

<u>The rise in the volume = 6.66 mL</u>
