Answer:
I don't really understand the question but fire water air and like earth but you said 3
Explanation:
The electric force between two point charges is given by:
F = (1/(4πε₀))Qq/r²
F is the electric force, Q and q are the two charges, and r is the distance between the charges.
F is proportional to the inverse square of r. That means if you increase r by a factor k, then F will decrease by a factor k².
Choice E.
Answer:
Explanation:
From the question we are told that:
Mass 1 
Speed 1 
Mass 2 
Generally the equation for momentum is mathematically given by
Where
Therefore
Answer:
The wooden floor exerts a greater force to give the same impulse as a padded mat.
Explanation:
-The wooden floor exerts a greater force for the same impulse as the padded mat.
-Unlike the wooded floor, the padded mat absorbs some of the energy when you fall. This in turn makes it exert less force on the body during the fall.
-Hence, you are less hurt when you fall on the padded floor.
