Deciliter = 1/10 of a liter
Milliliter = 1/1000 of a liter
So, there are 100 milliliters in one deciliter
The question is asking for "time".
Even if you didn't know anything about waves, you could look down this list and see that 'peak', 'amplitude', and 'frequency' are not times, so none of those can be the answer to the question. It must be <em>"period"</em>.
Answer:
B) Its horizontal velocity component is the same as it was just as it was launched
Explanation:
From dynamic we know that free falling objects had two components of velocity
The only acceleration that takes place in this case is gravity in the y-component of velocity
Since a=0 and 
that means that the velocity at the y-component changes with time but the horizontal component remain the same
This means that the horizontal velocity is not 0 but is <u><em>the same as it was just as it was launched</em></u>
