In all cases, except case 1 the forces are unbalanced, and therefore, the net force is different from 0.
<h3>How forces act?</h3>
In physics, forces are balanced if opposite forces have the same magnitude, for example:
- If two people are pulling a rope with a 5N force the forces are balanced and the rope will not move.
Based on this, from the diagrams presented only diagram 1 has balanced forces because this is the only case in which opposite forces have the same magnitude.
<h3>Let's calculate the net force in each case or the total sum of forces. </h3>
To do this, consider that forces pointing upwards and to the right are positive.
Case 1
- Net force: 10 N + 10 N - 10 N - 10 N = 0 N
Case 2
- Net force: 10N + 15 N - 10 N - 10 N = 5 N
- The direction of this object is to the right because the strongest force goes in that direction.
Case 3
- Net force: 17 N + 17 N - 10 N - 12 N = 12 N
- The direction of this object is to the right and upwards because these are the two strongest forces.
Case 4
- Net force: 17N + 10 N - 10N - 12 N = 5 N
- This object will move upwards because this is the strongest force.

they're called tides caused by the moon. the answer is tides
Absorb and transport solar energy
Answer:
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.
