Answer:
The answer to your question is because of the force of friction between the ball and the ground.
Explanation:
Exactly, Newton's first law states that every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impress on it.
After analyzing Martin's experiment we could conclude that Newton's first law of motion is wrong but we must remember that between a body and the surface there is a force of friction that causes that the object comes to stop.
We can not see this force but it is there.
Answer:
I believe it's qualitative and continuous.
Explanation:
Group 2A of the Periodic table contains the Alkaline Earth matals. Those elements are: Beryllium ( Be ), Magnesium ( Mg ), Calcium ( Ca ), Strontium ( Sr ), Barium ( Ba ) and Radium ( Ra ). Beryllium is the lightest member of the group 2A. Ionic radius increases moving down the group ans decreases from left to right across the period of elements. In the group 2A ionic radius increases from Beryllium ( 59 pm - picometers ) to Radium ( 163 pm ). Answer: Beryllium<span> has the lowers ionic radius. </span>
