Answer:
For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects.
Explanation:
Every force sent into an object will sent a force in return.
If you smack a table, you can feel the table "push back"
Answer:
1728.42857143 m/s²
0.00155883061577 s
259.264285715 m/s²
0.0103922041051 s
The child will get injured if he/she falls on a hardwood floor
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration
g = Acceleration due to gravity = 9.81 m/s²


Magnitude of deceleration is 1728.42857143 m/s²

Time taken is 0.00155883061577 s

Magnitude of deceleration is 259.264285715 m/s²

Time taken is 0.0103922041051 s
It is likely that the child will get injured if he/she falls on a hardwood floor.
It is less likely that the child will get injured if he/she falls on a carpeted floor.
Answer:

Explanation:
From the question we are told that
Magnitude 1 
Magnitude 1 
Generally the Pythagoras equation for the magnitudes is mathematically given as



Therefore resultant magnitude is

<span>vibrations that travel through the air or another medium and can be heard when they reach a person's or animal's ear.</span>
Assuming that the table has 4 legs. the upward force is equal to the downwardd force. the downward force of the table is the weight of the table. so the upward force is also the weight of the table but in opposite direction, so the upward force in on one leg is 1/4 of the weight of the table
