Answer:
8F_i = 3F_f
Explanation:
When two identical spheres are touched to each other, they equally share the total charge. Therefore, When neutral C is first touch to A, they share the initial charge of A equally.
Let us denote that the initial charge of A and B are Q. Then after C is touched to A, their respective charges are Q/2.
Then, C is touched to B, and they share the total charge of Q + Q/2 = 3Q/2. Their respective charges afterwards is 3Q/4 each.
The electrostatic force, Fi, in the initial configuration can be calculated as follows.
<h3><u>Given</u><u>:</u><u>-</u></h3>
- Initial velocity,u = 23 m/s
- Acceleration,a = 1.8 m/s²
<h3><u>To</u><u> </u><u>be</u><u> </u><u>calculated:-</u><u> </u></h3>
Calculate the final velocity,v .
<h3><u>Solution:-</u><u> </u></h3>
As we know that,
Acceleration = v - u / t
⇒ 1.8 = v - 23 / 6.8
⇒ 1.8 × 6.8 = v - 23
⇒ 12.24 = v - 23
⇒ v = 12.24 + 23
⇒ v = 35.24 m/s
Thus,the final velocity of a car is 32.24 meters per seconds.
I know
the answer do you want me to help you?
The equation of motion of a particle is given by,
s =
Let velocity of particle is denoted by v.
The velocity of the particle is given by,
velocity (v) =
v =
v =
v =
Thus, Velocity of particle is given by,
v =
Let acceleration of the particle is denoted by a.
The acceleration of particle is given by,
Acceleration =
a =
a =
a = 12t - 16
Thus, acceleration of the particle is given by,
a = 12t - 16
I believe the answer is 'A'
