<span>The particles in a gas are apart and moving fast, so the forces of attraction are too weak to have a noticeable effect.</span>
They are the same. If this is all happening on Earth, then the ball's acceleration is 9.8 m/s^2 in either case. That's the acceleration of gravity around here.
Answer:
The magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force. ( ¹/₄ F)
Explanation:
The electrostatic force between two charges is given by Coulomb's law;

where;
Q₁ and Q₂ are the magnitude of the charges
r is the distance between the charges
k is Coulomb's constant
Since the charges are identical;
Q₁ = Q
Q₂ = Q
the electrostatic force experienced by each charge is given by;

When each of the spheres has lost half of its initial charge;
Q₁ = Q/2
Q₂ = Q/2

Therefore, the magnitude of electrostatic force on each charge is quarter of the magnitude of initial electrostatic force.
An electron cloud is a visual model of the most probable locations of electrons in a atom. The cloud is denser where you will probably find a electron.
Answer:
d. 32.0 rad
Explanation:
The angular speed, denoted by ω can be calculated thus;
ω = θ /t
Where;
ω = angular speed in radians/sec
θ = angle in radians
t = time in seconds
∆ω = final ω - initial ω
ω = 12.00 rad/s - 4.00 rad/s
ω = 8.00 rad/s
Hence, using ω = θ/t
8.00 = θ/4
θ = 32.00rad
