Nitrogen forms many chemical compounds, such as amino acids, ammonia, nitric acid and cyanide.
Answer:
True
Explanation:
The Sun rotates in the counterclockwise (CCW) direction when seen from its north pole. Since, the planets revolve around the Sun because of its gravity, the revolution of all the planets and their moons as seen from the north of the Sun is in CCW direction.
In fact most of the solar system bodies rotate in the same direction that is CCW. Some major exceptions to this are Venus and Uranus.
Almost all the planets and moons were made from the planetary disk around the Sun. Thus, they lie nearly in the same plane.
The answer would be 22.50cal
Answer:
The two forces acting on a boat or some other floating object are buoyancy and gravity
The momentum of block B after the collision is -50 kg m/s.
Explanation:
We can solve this problem by using the principle of conservation of momentum. In fact, the total momentum of the system before and after the collision must be conserved, so we can write:
where:
is the momentum of block A before the collision
is the momentum of block B before the collision
is the momentum of block A after the collision
is the momentum of block B after the collision
Solving for , we find:
So, the momentum of block B after the collision is -50 kg m/s.
