Write with proper signs

Answer 1

Answer:

As submarine is at a depth of 512 metres below sea level is represented by -512 meters

Answer 2

Answer:

The depth is $-512m$.

Step-by-step explanation:

We are given that submarine is at a depth of $512m$ below sea level.

We need to write this depth with proper sign conventions.

A submarine is a watercraft which is capable independent operation underwater.

It is different from a submersible. Submersible has more limited underwater capability.

If the height is above sea level, we use positive sign.

If height is below sea level, we use negative sign.

Here, it is at depth and below sea level, we will use negative sign.

So, depth is $-512m$.
