7 0

Answer:

Leaves were generally lost as a water conservation measure so that transpiration would not drain the cactus of water in its desert environment. Stems grew into large reservoirs to hold any water brought into the cactus.

Calculate the net force on the Fx and Fy of 20 N 17 N 45.50 250

marysya [2.9K]

Answer:

$F_{net}$ is 26.25 N

Explanation:

Given that: $F_{x}$ = 20 N, $F_{y}$ = 17 N.

This implies that the two forces are acting at right angle to each other. Thus applying the Pythagoras theorem, we have;

$F_{net}$ = $\sqrt{F_{x} ^{2} + F_{y} ^{2} }$

= $\sqrt{(20)^{2} + (17)^{2} }$

= $\sqrt{400 + 289}$

$F_{net}$ = $\sqrt{689}$

= 26.2488

$F_{net}$ = 26.25 N

The net force is 26.25 N.
