<span>B. Compression causes upward vertical movement.</span>
Answer:
Explanation:
Let's use the kinematic equation
s = ut + ½at²
Where
s = distance fallen
u = initial velocity
t = time taken
a = acceleration
Here the hammer is dropped so a = g = gravitational acceleration
u = 0 because the hammer is dropped.
So by substituting you get,
1000 = 0 + ½×10×t²
t² = 200
t = 14.14 s
Answer:
From the relation above we can conclude that the as the distance between the two plate increases the electric field strength decreases
Explanation:
I cannot find any attached photo, but we can proceed anyways theoretically.
The electric field strength (E) at any point in an electric field is the force experienced by a unit positive charge (Q) at that point
i.e

But the force F

But the electric field intensity due to a point charge Q at a distance r meters away is given by

<em>From the relation above we can conclude that the as the distance between the two plate increases the electric field strength decreases</em>
