Answer:
East
Explanation:
Given Newton's third law of motion; "Action and reaction are equal and opposite", when a student jumps off a sled toward the west after it stops at the bottom of an icy hill, the sled will move in the East direction.
This is because, the force exerted on the sled is a reaction force and is opposite in direction to the force that thrusts the boy westward though equal in magnitude with the former.
The answer should be compound
Answer is: the collision theory.
The collision theory states that a certain fraction of the collisions (successful collisions) cause significant chemical change.
The successful collisions must have enough energy (activation energy), on this diagram that energy is represented with arrow up.
Chemical bonds are broken (between blue and red-black molecules) and new bonds are formed (between blue-red and blue-black molecules), as it is represented on diagram.
Answer:
No
Explanation:
No, this is an addition reaction
HC≡CH + 2H-H ----> H3C - CH3
The segment of the myocardial conduction framework that has the quickest rate of unconstrained depolarization is the S-A node.Depolarization goes through particular conduction pathways from the S-A hub to the A-V hub. This atrial depolarization happens at a most extreme rate of 0.3 m/sec
