They'll vibrate at their characteristic resonant frequency. That depends on the material the object is made of and its shape.
<h3><em>If two objects with the same charge are brought towards each other the force produced will be repulsive, it will push them apart. If two objects with opposite charges are brought towards each other the force will be attractive, it will pull them towards each other.</em></h3><h3><em>hope it helps.... thank you....</em></h3>
Answer:
The rock's speed after 5 seconds is 98 m/s.
Explanation:
A rock is dropped off a cliff.
It had an initial velocity of 0 m/s. And now it is moving downwards under the influence of gravitational force with the gravitational acceleration of 9.8 m/s².
Speed after 5 seconds = V
We know that acceleration = average speed/time
In our case,
g = ((0+V)/2)/5
9.8*5 = V/2
=> V = 2*9.8*5
V = 98 m/s

Let your initial displacement from your home to the store be
Dd

1 and your displacement from the store to your friend’s house
be Dd

2.
Given: Dd

1 = 200 m [N]; Dd
>
2 = 600 m [S]
Required: Dd

T
Analysis: Dd

2
Solution: Figure 6 shows the given vectors, with the tip of Dd

1
joined to the tail of Dd

T is drawn in red,
from the tail of Dd

T is [S].
Dd

T measures 4 cm in length in Figure 6, so using the scale of
1 cm : 100 m, the actual magnitude of Dd

T is 400 m.
Statement: Relative to your starting point at your home, your
total displacement is 400 m [S].
