The normal force would be the opposing and equal force to gravity ... that is why the box isn't floating or going through the ground ... this is Newton's third law of motion
Explanation:
Social learning is a hypothesis of learning cycle and social conduct which suggests that new practices can be procured by noticing and copying others. This impacts children because they do things they do not want to.
The only equation you need is the Δy = v₀t + 1/2at², and in this case, v₀t = 0 because the swimmers are starting from rest. Therefore, Δy = 1/2at², and that is 1/2 x (10m/s²) x (1.5)² = 11.25m.
With sigfigs it is 11m.
Gravitational potential energy = mass (kg) x gravitational field strength (N/kg) x height (m)
Therefore,
3 x 0.45 x 10 = 13.5J <- it's joules because it's energy
