Na chemical reaction, activation energy increases the of the reactants. this outcome causes the particles to collide, which results in the of new products.

Ariver current has a velocity of 5km/h relative to the shore, and a boat moves in the same direction as the current at 5 km/h relative to the river. how can the velocity of the boat relative to the shore be calculated?
