Answer:
Explanation:
First displacement of the particle is given as
= 11 m at 82 degree with positive X axis
so we can say
resultant displacement of the particle after second displacement is given as
r = 8.7 m at 135 degree with positive X axis
so we can say
now we know that
now we have
so we will have
so angle of the second displacement is given as
The metric unit is the Newton (N), or the
Explanation:
by inches to centimeter u can convert to meters

Answer:
The reaction only takes place if the reactants are in contact, then the surface exposed is very important because as the exposed surface of the reactants increases, the reaction velocity also increases. If the lumps are not broken up, a big amount of baking soda would be only available to react after the surrounding soda has already reacted.
