We use the kinematic equation,
Here, s is the distance traveled by elevator u is the initial velocity and t is time.
As elevator accelerates uniformly from rest to a speed of 2.5 m/s in 12 s, so

Thus, the distance the elevator travels during 12 s time is
The chart is quantitative and the beakers are qualitative.
Quantitative things always include numbers or data.
Qualitative things are based on observation.
ANY DENSE OBJECT
A mathematical equation for density is: Density = mass/volume or D = m/v. If something has a large mass compared to its volume, it has a high density. This is like a set of weights which can be small but heavy. But if an object has a small mass compared to its volume it has a lower density.
Pls give me a brainliest if this helps thx
