Question

A box has the dimensions 10cm×12cm×14cm A fly staring at one corner ends up at a diametrically opposite corner .find the magnitude of its displacement
a.36 cm
b.26 cm
c.20cm
d.16cm
​

Answer 1

Answer

◆ ▬▬▬▬▬▬ ❴✪❵ ▬▬▬▬▬▬ ◆

The magnitude of displacement ,

$d \: = \sqrt{ {l}^{2} } + {b}^{2} + {h}^{2} \\ l \: = 10 \: m \\ b \: = 12 \: m \\ h \: = 14 \: m \\ d = \sqrt{ {(10)}^{2} } + {((12)}^{2} + {(4)}^{2} ) \\ - \sqrt{100 + 110 + 186} \\ = \sqrt{340 + 100 } \\ \sqrt{440} = \sqrt[2]{110} \\ d = 20$

mark as a brain least plzzz
