A). Kepler's first law of planetary motion ... "Each planet moves
in an elliptical orbit, with the Sun at one focus of the ellipse."
B). Heliocentric motion ... motion in an orbit around the Sun.
C). Eccentricity ... what makes an ellipse different from a circle.
The eccentricity of a circle is zero.
The eccentricity of the Earth's orbit is very small.
The eccentricity of a comet's orbit is big.
D). Retrograde motion ... the apparent, temporary, backward
motion of a planet on its path through the stars.

Answer:
C. A glass of lemonade starting to freeze in a warm room.
Explanation:
This is because there is no source of cold to properly freeze the lemonade, freezing happens when a cold source starts to slow down the movement of atoms. So if there's nothing there to freeze it, it can't freeze.
Alternatively, there are some materials that harden when not subjected to heat, but that's not freezing. It's just cooling.
Answer:
0.667 m/s
Explanation:
Given that,
Mass of a rubber bullet, m₁ = 20 g = 0.02 kg
Initial speed of rubber bullet, u₁ = 60 m/s
Mass of the wood block, m₂ = 3 kg
Initial speed of the wooden block, u₂ = 0
A rubber bullet hits the stationary wood block. The rubber bullet ricochets off the wood block with a velocity of 40.0 m/s in the opposite direction.
Final speed of rubber bullet, v₁ = -40 m/s
Using the conservation of momentum. It will remains conserved. Let v₂ is the velocity of the wood block.
So, the velocity of the wood block is 0.667 m/s.
So if the cyclist travels on average 128 km each day, then it will take
