A wooden block measuring 50 cm by 100 cm by 200 cm has a mass of 8000 g.

photoshop1234 [79]

The density of the block is mathematically given as

$\phi=8e-4$

<h3>Density of block</h3>

Question Parameters:

50 cm by 100 cm by 200 cm has a mass of 8000 g.

Generally the equation for the density is mathematically given as

$phi=\frac{m}{v}$

Where

v= 50 cm * 100 cm * 200 cm

v=1000000cm

v=10000m

Therefore

$phi=\frac{m}{v}\\\\phi=\frac{8}{10000}$

phi=8e-4

An object moves along the grid through the points A, B, C, D, E, and Fas shown below.

sveticcg [70]

Answer:

Total distance = 6.5 km

Explanation:

Let the distance be denoted by the vectors drawn from A, B, C, D, E, and F.

Then the distance covered can be calculated by adding the vectors in the direction given.

Total distance = 3km + 1km+ 1.5km+ 0.5km+ 0.5km

Total distance = 6.5 km

If we were to find the displacement ( shortest distance) then the head to tail rule would be applied using the vectors.
