A block on an inclined plane experiences a force due to gravity of 300 N straight down. If the slope is inclined at 67. 8° to the horizontal;

(a) what is the component of the force due to gravity perpendicular and parallel to the slope? and
(b) at what angle would the perpendicular and parallel components of the force due to gravity be equal?

Correct (a) F|| = 277.8 N  and F⊥ = 113.4 N  (b) α = 45°

Explanation:

Given :

Fg = 300 N  and angle α = 67.8°

Let be perpendicular component be F⊥ and parallel component F||

(a)

F|| = Fg · sinα = 300 · sin 67.8° = 300 · 0.926 = 277.8 N

F|| = 277.8 N

F⊥ = Fg · cosα =  300 · cos 67.8° = 300 · 0.378 = 113.4 N

F⊥ = 113.4 N

(b)

Perpendicular and parallel components will be equal at angle

α = 45°

F⊥ = F|| = Fg · sinα = Fg · cosα =  300 · √2/2 =  212.13 N

scorpions are,

c.arachnids

  scorpions are animals in the order scorpiones, under the class arachnida, which makes them a distant cousin of spiders

happy to

pls mark as brainliest.

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
