The answer is X. I hope this helped
Answer:
The correct option is;
Sun, planets, moons, asteroids, comets
Explanation:
The Solar System consists of the system of celestial bodies bound gravitationally to the Sun, which includes the 8 regular planets, 2 dwarf planets, 796, 354 known minor planets, 4,143 comets, moons, which are natural satellites, an asteroid belt, which consists of a belt of rock and metal containing celestial bodies moving in a belt round the Sun
The velocity of the wood board which is resting on very smooth ice in the middle of a frozen lake relative to this ice is 0.905 m/s
- What is conservation of momentum:
It states the amount of momentum remains constant
Momentum of a moving body is the product of mass times velocity.
Formula for momentum:
When the two objects collides, then the initial collision of the two body is equal to the final collision of two bodies by the law of conservation of momentum.
here,
mass of wood, m=58.5 kg
mass of boy, M=41.7 kg
velocity of the boy V=1.27 m/s
Thus,
The conservation of momentum,
m*v = M*V
substituting the value,
(58.5*v) = 1.27* 41.7
v = 52.95 / 58.5
v = 0.905 m/s
Thus, the velocity of the wood board which is resting on very smooth ice in the middle of a frozen lake relative to this ice is 0.905 m/s.
