Answer:
You may know that both velocity and acceleration have something to do with how fast an object moves. You’re right, but what’s the difference between these two terms in physics? Keep reading for more information about velocity, acceleration, and how to tell them apart.
Explanation:
The frequency of the wave is the frequency of that sine function ... 2,000π ... but that's the <u>angular </u>frequency, in radians per second.
To convert angular frequency to Hz, we have to divide by 2π.
So the frequency of this wave is <em>1,000 Hz. </em>
4 main components are: Nitrogen, Oxygen, Argon and water vapour
(A) The oxygen atom becomes strongly negative.
Explanation:
When a very electronegative atom like oxygen bonds to an atom with a lower electronegativity, like lithium, the oxygen atom becomes strongly negative and the lithium becomes strongly positive.
The attraction between these oppositely charged ions results in the formation ionic bond.
- An ionic bond is an interatomic bond in which a highly electronegative atom is bonded to less electronegative one.
- The electronegative nature of the oxgyen allows is to gain the electrons lost by weakly electronegative lthium.
- Most metals have low electronegativity.
- They then both will form ions.
- The attraction between the oppositely charged ions results in an ionic/electrovalent bonding.

Answer:
The change in momentum is 
Explanation:
From the question we are told that
The time taken for the stone to stop is 
The net force on the rock is 
The impulse of the rock can be mathematically represented as
Substituting values
Now impulse is defined as the rate at which momentum change
Hence the change in momentum 
of the rock is equal to the impulse of the rock
So
