Answer:
I think its object 1
Explanation:
Because the object that has more weight has a greater momentum and the lightest object that has a less momentum will be easier to change because its lighter.
 
        
             
        
        
        
Answer:
 adapted from NOVA, a team of historians, engineers, and trade experts recreate a medieval throwing machine called a trebuchet. To launch a projectile, a trebuchet utilizes the transfer of gravitational potential energy into kinetic energy. A massive counterweight at one end of a lever falls because of gravity, causing the other end of the lever to rise and release a projectile from a sling. As part of their design process, the engineers use models to help evaluate how well their designs will work.

Answer:
1–
Explanation:
The fluorine is the element with biggest electronegativity in the periodic table, so it usually always take an electron and gets charge 1–
 
        
             
        
        
        
Answer:
The charge stored in the capacitor will stay the same. However, the electric potential across the two plates will increase. (Assuming that the permittivity of the space between the two plates stays the same.)
Explanation:
The two plates of this capacitor are no longer connected to each other. As a result, there's no way for the charge on one plate to move to the other.  , the amount of charge stored in this capacitor, will stay the same.
, the amount of charge stored in this capacitor, will stay the same.
The formula  relates the electric potential across a capacitor to:
 relates the electric potential across a capacitor to:
 , the charge stored in the capacitor, and , the charge stored in the capacitor, and
 , the capacitance of this capacitor. , the capacitance of this capacitor.
While  stays the same, moving the two plates apart could affect the potential
 stays the same, moving the two plates apart could affect the potential  by changing the capacitance
 by changing the capacitance  of this capacitor. The formula for the capacitance of a parallel-plate capacitor is:
 of this capacitor. The formula for the capacitance of a parallel-plate capacitor is:
 ,
, 
where
 is the permittivity of the material between the two plates. is the permittivity of the material between the two plates.
 is the area of each of the two plates. is the area of each of the two plates.
 is the distance between the two plates. is the distance between the two plates.
Assume that the two plates are separated with vacuum. Moving the two plates apart will not affect the value of  . Neither will that change the area of the two plates.
. Neither will that change the area of the two plates. 
However, as  (the distance between the two plates) increases, the value of
 (the distance between the two plates) increases, the value of  will become smaller. In other words, moving the two plates of a parallel-plate capacitor apart would reduce its capacitance.
 will become smaller. In other words, moving the two plates of a parallel-plate capacitor apart would reduce its capacitance.
On the other hand, the formula  can be rewritten as:
 can be rewritten as:
 .
.
The value of  (charge stored in this capacitor) stays the same. As the value of
 (charge stored in this capacitor) stays the same. As the value of  becomes smaller, the value of the fraction will become larger. Hence, the electric potential across this capacitor will become larger as the two plates are moved away from one another.
 becomes smaller, the value of the fraction will become larger. Hence, the electric potential across this capacitor will become larger as the two plates are moved away from one another.
