Answer:
1) H. magnitude, 2) D. coordinates, 3) G. distance.
Explanation:
1) A vector has, by definition, both <em>magnitude</em> and direction. (Reason: Scalars have only magnitude)
2) Once you have selected a coordinate system, you can express a two-dimensional vector using a pair of quantities known collectively as <em>coordinates</em>. (Reason: Coordinates are ordered pairs)
3) Speed differs from velocity in the same way that <em>distance</em> differs from displacement. (Reason: The distance is the magnitude of displacement)
There is no thing here I can answer so imma just say all of the above because I have no idea what else to say so thx for the points
Answer:
![F_{net} = 6.879\times 10^{- 7}\ N](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%206.879%5Ctimes%2010%5E%7B-%207%7D%5C%20N)
Solution:
As per the question:
Mass of first object, m = 120 kg
Mass of second object, m' = 420 kg
Mass of the third object, M = 69.0 kg
Distance between the m and m', d = 0.380 m
Now,
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m:
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m':
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m and m':
![F_{net} = F + F'](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20F%20%2B%20F%27)
![F_{net} = 1.529\times 10^{- 7} + 5.35\times 10^{- 7} = 6.879\times 10^{- 7}\ N](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%201.529%5Ctimes%2010%5E%7B-%207%7D%20%2B%205.35%5Ctimes%2010%5E%7B-%207%7D%20%3D%206.879%5Ctimes%2010%5E%7B-%207%7D%5C%20N)
It’s D. An enlargement (hope this helps!)
