The picture on the left represents the reactants in the equation and the picture on the right represents the products. Does this
reaction follow the law of conservation of matter?
• No,there are different kinds of atoms are present in the products as in the reactants.
•No, because there are new products than the reactants.
•No, because there are not the same number of molecules in the product side as in the reactant side.
•yes, the same number and kind of atoms are present in the products as in the reactants.

Answer:
33.6371 m
Explanation:
t = Time taken
u = Initial velocity = 20.3 m/s
v = Final velocity
s = Displacement
a = Acceleration = -7 m/s²
Distance traveled in the 0.207 seconds
Distance = Speed × Time
⇒Distance = 20.3×0.207 = 4.2021 m
Equation of motion
Distance traveled by the car while braking is 29.435 m
Total distance measured from the point where the driver first notices the red light is 29.435+4.2021 = 33.6371 m
