' B ' is the only choice on the list that tells you a definite place, where you could go to pick up the object or meet somebody.
But in order to use it, you also have to know where the origin of coordinates is ... the point (0, 0) .
__________
No, I'm wrong about that. You have to know where SOME other point is, but that doesn't have to be (0, 0).
X = v0+ 1/2 a t^2
X= 0+1/2(12 m/s^2 ) ( 7 s)^ 2
X= 6 m/s^2 ( 49 s^2)
X= 294 m
Answer:
c. 7.5 m/s south
Explanation:
<u>Given the following data;</u>
Velocity of duck = 10m/s due South
Velocity of wind = 2.5m/s
To find the resultant velocity;
Since we know that the duck is flying against a gust of wind, we would have to subtract the velocity of the gust of wind from that of the duck.
This ultimately implies that, the gust of wind (headwind) would decrease the resulting velocity of the duck because it approaches the duck from the front.
Resultant velocity, /V/ = 10 - 2.5
Resultant velocity, /V/ = 7.5m/s South.
<em>Therefore, the resultant velocity of the duck is 7.5m/s south. </em>
Answer:
B .Limited types of data Insufficient data
Explanation:
To analyse and making decision from big data we have following thing
- Sufficient data
- data analyst
- Accurate data
- data Privacy
- data storage
So, limited data or data that cannot be copied is not and obstacle in data handling. hence option B Limited types of data Insufficient data is correct.
Answer:
The set of coefficients that would correctly balanced the equation
NaCl → Na + Cl2 is the option D
(2,2,1)
Explanation:
In this reaction sodium chloride splits into sodium and chlorine.
For balancing the equation we should have number of atom of the element in the left hand side equal to the number of atom of the same element in the right-hand side.
so here in left hand side only one sodium and one chlorine is given and in the right-hand side one sodium and two chlorine is given.
So for the balancing the equation both the side should be same.
So we will write the balanced equation as
2NaCl → 2Na + Cl2
So, right now it is balanced that is two sodium and two chlorine on the left hand side as well as the right hand side.
Hence the coefficients are
2, 2, 1
