Why is it more comfortable to fall onto a big pillow than onto a wooden floor ?

1 answer:

6 0

I believe the answer to this question is C. The pillow distributes the decelerating force over a greater amount of time .

sudden stops are damaging, not the fall itself.

When falling on a mat it will take longer since a smaller force=longer falling time

when falling on a wooden floor it will take shorter since a larger force=smaller falling time

Hence, if the sudden fall is what causes impact and discomfort, and a smaller force equals longer falling time, and a larger force equals shorter falling time and smaller falling time equals less impact, then, C. must be the answer.

Answer:

Explanation:

She's correct but doesn't mean the wagon cannot put into motion. The force that she applied on the wagon, according to Newton's 2nd law, would have generated an acceleration, which translates into motion. The reaction force the wagon applies on her due to Newton's 3rd law, would not hinder its own motion.

Aristotle supported which of these views?

katrin2010 [14]

The answer is A. The Sun and all the planets revolve around Earth.

Aristotle believed that the Earth was the centre of the solar system, and the Sun and the planets orbited around it. He believed that the universe was composed of Earth-like bodies, which were at rest, and of heavenly bodies, which were in perpetual motion.

creativ13 [48]

Answer:

a) b) d)

Explanation:

The question is incomplete. The Complete question might be

In an inertial frame of reference, a series of experiments is conducted. In each experiment, two or three forces are applied to an object. The magnitudes of these forces are given. No other forces are acting on the object. In which cases may the object possibly remain at rest? The forces applied are as follows: Check all that apply.

a)2 N; 2 N

b) 200 N; 200 N

c) 200 N; 201 N

d) 2 N; 2 N; 4 N

e) 2 N; 2 N; 2 N

f) 2 N; 2 N; 3 N

g) 2 N; 2 N; 5 N

h ) 200 N; 200 N; 5 N

For th object to remain at rest, sum of all forces must be equal to zero. Use minus sign to show opposing forces

a) 2+(-2)=0 here minus sign is to show the opposing firection of force

b) 200+(-200)=0

c) 200+(-201) $\neq$ 0

d) 2+2+(-4)=0

e) 2+2+(-2) $\neq$ 0

f) 2+2+(-3) $\neq$ 0; 2+(-2)+3 $\neq$ 0

g) 2+2+(-5) $\neq$ 0; 2+(-2)+5 $\neq$ 0

h)200 + 200 +(-5) $\neq$ 0; 200+(-200)+5 $\neq$ 0
