Answer:
Action and Reaction
Explanation:
For every force, there is one of equal and opposite also. Think of it this way. When you try to push on a wall, you are applying a force. However, that wall is also pushing back on you with that same force. You can also see this when you high five someone. You can slap as hard as you want to their stationary hand, but due to the 3rd law, you're both going to be left with red hands do to the amount of force applied.
Answer:
An object with negative acceleration could be speeding up, and an object with positive acceleration could be slowing down. ... Consider the fact that acceleration is a vector that points in the same direction as the change in velocity.
Explanation:
Answer:
gas < liquid < solid
Explanation:
As we know that density is defined as ratio of mass and volume of the object.
So here if all the molecules of the given matter is packed very close to each other then it can be said that density is high.
So here we know that solids are packed tightly to each other such that force of attraction between them is good then this is said to be high density while in gases the molecules have weak force between them so the packing of the molecules are not too good.
So here we can say that the correct order of density from least to highest is given as
gas < liquid < solid
It is the second one, it is longitude and moving up and down so its B.
