Answer:
7 units, north
Explanation:
This is a problem of vector subtraction. We have:
- Vector A: magnitude 2 units, direction to the north
- Vector B: magnitude 5 units, direction to the south
If we take the north as positive direction, we can write
Since we want to find (vector subtraction), we have to change the sign of B, so we find:
And the positive sign means the direction is north.
True, <span>a material with high specific heat needs a lot of heat energy for its temp. to go up.</span>
Force = (mass) x (acceleration)
Mass = 2000 grams = 2 kilograms
Force = (2 kg) x (8.3 m/s²)
Force = <em>16.6 Newtons</em>
