It will be .02 m/s because when we convert m to km its 1000 m = 1 km or 1 m = .001 km
Hope this helps!
It takes 29.5 days for a new moon to occur approximately after a full moon.
I apologise if this is confusing, if it doesn’t make sense just comment and I’ll try to explain it better. :)
Let’s seperate the four directions into two categories: north + south, and east + west.
John’s movements in regards to a north/south direction over the course of the entire placement:
8 north, 8 south (6 + 2 steps = 8 steps south)
In total, John moved both north and south 8 times each.
8 - 8 = 0, therefore canceling out any north/south movement. At this stage, John has not moved from his starting position.
John’s movement in regards to east/west:
6 west, 3 east.
Since he has not moved an equal amount of steps west and east means he HAS moved from his starting point.
In order to find John’s displacement, we must take his east steps from his west steps.
6 - 3 = 3
This means John’s displacement from his starting point is 3 steps west.

Explanation:
<u>Density
</u>
The density of a substance is the mass per unit volume. The density varies with temperature and pressure.
The formula to calculate the density of a substance of mass (m) and volume (V) is:
The cube has a mass of m=3.75 g and a volume of V=3 ml, thus the density is:
Since 1 kg=1000 mg and 1 lt = 1000 ml, the density has the same value but with different units:
