I need help on this question, please.

frez [133]

Answer:

|X| = 72 cm

Explanation:

We need to find the magnitude of vector X.

Vector Y = 21 cm

Vector Z = 75 cm

We know that, the magnitude of resultant vector is given by :

$Z={X^2+Y^2} \\\\X^2=Z^2-Y^2\\\\X^2=(75)^2-(21)^2\\\\X=72\ cm$

So, the value of magnitude of vector X is 72 cm

Abox has a mass of 14.4 kg. The length is 4 m longthe width is 1 m and the height is 5 m. What is the density of the box?

valkas [14]

Answer:

0.72 kg per cubic m

Explanation:

Mass = 14.4 kg

Volume = lbh = 4*1*5 = 20 cubic m

$\because \: density \\ \\ = \frac{mass}{volume} \\ \\ = \frac{14.4}{20} \\ \\ = 0.72 \: kg {m}^{ - 3}$
