Answer:
The cars would both move in the direction with the greatest momentum. We know the truck would have the greatest momentum due to having the greatest mass. Plus, factors which affects momentum are mass and velocity.
Thus, the car would move forward towards the direction of momentum of the truck. Both will continue to move at the same velocity.
E.g. truck hits the back of a stationary car, both will move forward, to the right & travelling at the same speed, but lower than the initial velocity of the truck. Now the total the total momentum before the collision is the same as the total momentum after the collision; as a result, momentum has been conserved.

Answer:
The magnitude of the surface charge density on either plate is approximately 5.41 × 10⁻⁸ C/(m²)
Explanation:
The magnitude of the charge on each of the conducting plates = Equal
The orientation of the charges on each plate = Opposite charges
The magnitude of the point charge placed between the plates = +3.60 nC
The force acting on the point charge, q = 22.0 μN
Therefore, we have;
F = E × q
E = F/q = 22.0 μN/+3.60nC = 6,111.1111 V/m
We have;
Where;
ρ = The surface charge density
ε₀ = Absolute permittivity ≈ 8.85 × 10⁻¹² C²/(N·m²)
Therefore, we have;
ρ = E × ε₀ = 6,111.1111 V/m × 8.85 × 10⁻¹² C²/(N·m²) = 5.40833332 × 10⁻⁸ C/(m²)
∴ The magnitude of the surface charge density on either plate, ρ ≈ 5.41 × 10⁻⁸ C/(m²).
Answer:
The gravity of the sun and the planets works together with the inertia to create the orbits and keep them consistent. The gravity pulls the sun and the planets together, while keeping them apart. The inertia provides the tendency to maintain speed and keep moving. The planets want to keep moving in a straight line because of the physics of inertia. However, the gravitational pull wants to change the motion to pull the planets into the core of the sun. Together, this creates a rounded orbit as a form of compromise between the two forces.
