In the absence of an external force, a moving object will move with a constant velocity in a straight line.
This is according to Newton's first law of motion that states: An object continues to be in its state of rest or uniform motion and in the same direction not unless acted upon by an external force to change that state.
Answer: Well the answer is KE = 5.625E-7 i just don't know the units for it...
Hope this helps....... Stay safe and have a Merry Christmas!!!!!!!!!! :D
There are no true statements on the list you attached.
Answer:
Ionic or electrovalent bond
Explanation:
The electronegativity of an atom determines to what extent an atom would attract an electron towards it. So, they can form combine.
The nature of chemical bonding depends upon the difference between the electronegativity of the combining atoms.
When the electronegativity difference is
< 0.4 - forms non-polar covalent bonds
between 0.4 and 1.7 - polar covalent bonds
> 1.7 - ionic bond
Hence, when there is a large difference between the electronegativity of atoms, it forms ionic bonds.
Answer:
The distance separating the two particles when the moving particle is momentarily stopped is 0.947 m
Explanation:
Given that,
First charge = 40 μC
Second charge = 80 μC
Distance between the two particles = 2.0 m
Kinetic energy = 16 J
We need to calculate the distance separating the two particles when the moving particle is momentarily stopped
Using conservation of energy
Put the value into the formula
Hence, The distance separating the two particles when the moving particle is momentarily stopped is 0.947 m
