Given the diagram provided, we can confirm that the object will accelerate in a downward direction.
<h3>Why will it accelerate downwards?</h3>
The free-body diagram shows us the forces that are acting on this object. Through this diagram, we can see that the forces on the left and right of the object are balanced, meaning that there will not have movement in either of these directions.
The diagram shows that the downward force being applied is not balanced by an opposite force, so the object will accelerate in this direction.
Therefore, we can confirm that object will accelerate in a downward direction due to its downward force not being balanced by an opposing force.

Answer:
E the electric field remains unchanged.
Explanation:
potential difference between the plates of a capacitor
V = Q / C Where Q is charge on the capacitor and C is capacity of capacitor
Here Q is unchanged.
C the capacity has value equal to ε A / d
Here d is distance between plates. when it is halved, capacitance C becomes double.
V = Q /C , When C becomes double V becomes half
E = V/d , E is electric field between plates having separation of d.
When V becomes half and d also becomes half , there is no change in the value of E.
Hence E the electric field remains unchanged.
Answer:
Explanation:
element usual oxidation state exceptions
Group 2 metals always +2
Oxygen usually -2 except in peroxides and F2O (see below)
Hydrogen usually +1 except in metal hydrides where it is -1
Fluorine always -1
