Question

bird moves in such a way that it has a
displacement of 12 m towards east, 5 m
wwards north and 9 m vertically upwards.
Find the magnitude of its displacement.
1) 55m 2 ) 5/10 m
3) 5.5m
4) 5m​

Answer 1

Answer:

5*Root(10)

Explanation:

Apply Pythagoras Theorem

Answer 2

AnSweR:

By Pythogras Theorem,

$→\;{\sf{(AN)² = (AE)²+(EN)²}}$

$→\;{\sf{(AN)² = (12)²+(5)²}}$

$→\;{\sf{(AN)² = 144+25}}$

$→\;{\sf{AN = \sqrt{169}}}$

$→\;{\sf{AN = \sqrt{13²}}}$

$◕➜\;{\red{\bf{AN = 13cm}}}$
