Answer: Option (b) is the correct answer.

Explanation:

Acceleration means the rate of change of velocity of an object. Negative acceleration means a decrease in the velocity of an object. Positive acceleration means an increase in the velocity of an object.

When a car slows down for a stop sign then it is an example of negative acceleration as the speed of car is decreasing on seeing the stop signal.

Speed is the magnitude of velocity vector. Therefore, speed can never be negative.

Thus, we can conclude that a car slowing down for a stop sign is an example of negative acceleration.

In a titration, 45.0 mL of KOH is neutralized by 75.0 mL of 0.30M HBr. How much KOH is in 1.0 liter of the KOH solution ?

photoshop1234 [79]

KOH + HBr ---> KBr + H2O

0,3 moles of HBr ---in-------1000ml
x moles of HBr-------in------75ml
x = 0,0225 moles of HBr

according to the reaction: 1 mole of KOH = 1 mole of HBr
so
0,0225 moles of HBr = 0,0225 moles of KOH

0,0225 mole of KOH------in-----45ml
x moles of KOH -----------in------1000ml
x = 0,5 moles of KOH

answer: 0,5 mol/dm³ KOH (molarity)
