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.

Answer:
cantidad de impulso de movimiento. La cantidad de movimiento de un objeto se define como el producto de su masa por su velocidad. Cuando dos objetos chocan, la cantidad de movimiento de cada uno varía, pero la cantidad de movimiento total del sistema permanece constante, al menos con una buena aproximación.
De nada
Answer:Sometime decreases and sometime increases.
Explanation:
Given
Projectile is launched at
so horizontal velocity=ucos35
vertical velocity=usin35
since gravity acts in the vertical direction, therefore, it affects only the vertical component of the projectile.
So Vertical velocity first decrease up to maximum height and then starts to increase.
Answer:
450
Explanation:
total magnification = eyepiece lens x objective lens
10 x 45 = 450
