The best demonstration that applies to Newton's Third Law of motion would be D) When you walk your foot pushes down on the ground while the ground pushes back on your foot.
------------------
Newton's Third Law states that for every action, there is an equal and opposite reaction. This is actually explains that forces come in pairs and forces are an interaction between two objects. As per the correct option given in the question explains Newton’s Third Law.
------------------
When you walk your foot (say object A) pushes down on the ground while the ground (say object Q) pushes back on your foot with the same force but in the opposite direction.
The density of an object is the ratio of its mass over the volume. This translates to the amount of substance present in a certain space and can mathematically be expressed as,
density = mass / volume
In this item, we are given that the object of mass 1.41 kg is able to displace 0.314 L of liquid. The volume of water displaced is also the volume of the object. Hence,
density = 1.41 kg / 0.314 L = 4.49 kg/L
Then, we convert the calculated volume of g/mL.
density = (4.49 kg/L)(1 L / 1000 mL)(1000 g/1 kg)
<em> density = 4.49 g/mL</em>
It's C, angle of incidence is equal to angle of reflection
Answer:
the answer is b sorry if its wrong
Explanation:
<span>Use the cosine rule to solve for the distance the wind pushed them to the east and because this all happened in an hour, you can say they travelled this distance per hour.
+-130 km due east which means the wind speed was +-130km/h.
So for example i used a^2=b^2+c^2-2bc(cos75) b will be the distance they travelled and c= 135cos75=35km now all you do is substitute in and you will get your distance that the wind pushed them to the east and because it was an hour of travel the distance as said before will be per hour. </span>
