Answer all the question I have this due in 30 mins

Answer 1:

Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.

Answer 2:

Inclined planes are important parts of our lives! Have you ever slide down a slide? Or walked up the stairs in your house to your bedroom? You are using an inclined plane!

Answer 3:

An inclined plane, also known as a ramp, is a flat supporting surface tilted at an angle, with one end higher than the other, used as an aid for raising or lowering a load.[1][2][3] The inclined plane is one of the six classical simple machines defined by Renaissance scientists. Inclined planes are widely used to move heavy loads over vertical obstacles; examples vary from a ramp used to load goods into a truck, to a person walking up a pedestrian ramp, to an automobile or railroad train climbing a grade.[3]

Answer 4:

An inclined plane makes it easier to raise something heavy, like a rock. Instead of lifting the rock straight up, you can raise it from its original location with less force by pushing it up a ramp. ... In a steep ramp, it will be harder to push the rock but you won't need to push it as far.

Answer 5:

ladder.

sidewalk curb ramp.

slanted roof.

slide.

ramps, sloping roads, chisels, hatchets, plows, air hammers, carpenter's planes and wedges.

1 They are both a form of a triangle

2 A because The triangles going up in your pushing something so then it goes down a deep slope

3 B because the triangle slanted and rolling up something slanted is easier because it's not as much at work

Explanation:

one person pulls 90n one way and the other has 100n pulling the other way.

so the net force = 90 - 100 = -10n,

or the ans can be 10n if the picture shows -90n and 100n instead.
