The velocity of the car would be 100 kilometer per hour.
∆y is change in y (velocity) and ∆x is change in x (time)
So from the graph we see that ∆y is zero and ∆x is also zero (value is changing with same ratio)
∆y/∆x= slope = 0
The answer is D. A more reactive metal replaces a less reactive metal in a chemical reaction.
Answer:
180 degrees
Explanation:
if the waves are in phase this means that their frequency is doubled or amplitude is doubled
