Answer:
Distance covered 28 km
displacement is 22.8 km North-East
Explanation:
Distance shows how far apart objects or points are from each other. The distance he covered is the sum of all the distance travelled. Therefore:
Distance covered = 12 km + 6 km + 10 km = 28 km
Displacement is a vector quantity (has direction). It is the overall change in position.
The total distance traveled north = 12 km + 10 km = 22 km
The distance traveled east = 6 km
The displacement (d) is:
d² = 22² + 6² = 484 + 36
d² = 520
d = √520 = 22.8 km
Therefore the displacement is 22.8 km North-East

Answer:
A force of 75 N placed at 0.7 m on the meter stick.
Explanation:
The weight of the box is equal to:
The net torque is equal to zero and is equal to:
For a force with a value of 75 N that is placed at 0.70 m on the meter stick, it would produce a torque of 15 N m
If you replace that values in the equation:
