From what is known about collisions, picture 1 is an inelastic collision while picture 2 is an elastic collision.
<h3>What is elastic collision?</h3>
Elastic collision is a type of collision in which both the momentum and kinetic energy of the bodies are conserved.
- In elastic collision, the two bodies do not stick together.
<h3>What is inelastic collision?</h3>
Inelastic collision is a type of collision in which only the momentum is conserved but kinetic energy decreases
- In inelastic collision, the two bodies stick together.
Therefore, picture 1 is an inelastic collision while picture 2 is an elastic collision.

Answer:
About 32.6°
Explanation:
The tangent of the desired angle is the ratio of distance from the wall to height up the wall:
tan(angle of incidence) = (22.7 cm)/(35.5 cm) ≈ 0.63944
angle of incidence = arctan(0.63944) ≈ 32.6°
_____
The angle of incidence is measured from the normal to the mirror.
In order to escape the gravitational pull of our planet, any object must have an escape velocity of 7 km/s or more, anything lower than that will be slowed down by the pull of gravity, and will eventually returned to the surface of our planet. It is independent of mass, any lighter or heavier object must attain the required escaped velocity to reach space.
<span>To begin, the formula for finding frequency when wavelength is known is "f = c / w" when c is the constant velocity (3 * 10^8 m/s). To convert the wavelength into a common form (m/s), it will have to be multiplied by 10^-2. This leaves the equation as "f = 3.0 * 10^8 / (2.4 * 10^-5 * 10^-2), or 2.4 * 10^-7. This gives 1.25 * 10^15 m/s as the frequency.</span>
False. Mercury and Venus are known for having no natural satellites/moons. The absence of moons already prove that not all planets have moons larger than Pluto's Charon.
