Answer:

D. Newton's Third Law of Motion

Explanation:

Newton's law of gravity is definitely not applicable to your hands. So we can cross this bad boy out

Newton's First Law is F=MA (force equals mass times acceleration). This is basically the root of most physics but it isn't the reason for your hand being red after hitting a wall.

Newton's Second law deals with velocities and forces, so even though you are apply a force your are not changing the velocity of the wall much.

Newton's Third Law basically says that for whatever force you apply to an object, that object will apply an equal and opposite force back to you. This is why your hand gets red. When you slap the wall with all your strength, the wall hits your hand back with the same amount of force. The 2nd law can also be seen when you're trying to push a desk and it won't budge. You are pushing on it, but the desk is pushing back. (there are multiple other factors applicable like friction but we physicists like to ignore them :) )

I hope this helps!

In a bedridden patient recovering from a badly fractured femur, disuse atrophy in the thigh muscles is caused by _________.

Brut [27]

In a bedridden patient recovering from a badly fractured femur, disuse atrophy in the thigh muscles is caused by decreased synthesis of muscle proteins and/or increased breakdown of muscle proteins. Muscle tissue grows and heals in response to stress. Without the stress of exercise and normal daily activities, muscle tissue degenerates

Difference between sold and liquid

Tcecarenko [31]

Explanation:

Solids have closely packed particles and vibrate about a fixed position, they also have a fixed volume.

liquid have close particles but which are able to move with a bit of kinetic energy, for this reason they have no fixed volume but take the volume of the container or vessel

Which graph represents the solution set of the system of inequalities? {−2x+y≤4y>x+2

Jet001 [13]

Answer:

The fourth graph is the answer

Explanation:

We have inequalities

$-2x+y\leq 4$ $\rightarrow y\leq 2x+4$

$y>x+2$

For the first inequality all points at or below the graph of y are solutions, and for the second inequality all the points above the graph of y are the solutions. So, the solution to these inequalities are points that are above the graph of $y>x+2$ and below the graph of $y\leq 2x+4$ . The shaded region in the fourth graph satisfies these conditions.

Looking at other choices, we see that the first two graphs do not even represent the graphs of our inequalities, and the third graph does represent the inequalities but shades the wrong region.

P.S: the graph of the inequality $y>x+2$ is dashed because $y$ is "greater than" and not "equal to" $x+2$ , so this indicates that the values on the line $y=x+2$ are not included. And the graph of the inequality $y\leq 2x+4$ is a solid line because $y$ is "less than or equal to" $2x+4$ , so we are including the values on the line $y=2x+4$ , and that's why it's solid.
