Answer:
I think its hypogeal sorry if im wrong
Data given
Initial Velocity = 0 m/s
Change in distance x = 60m
Change in time = 3.5s
Acceleration due to gravity = -9.81 m/s^2
Required
Final Velocity (vf) = ?
Solution
According to first equation of motion
Vf = Vi+gt
Put the values, we will get
Vf = 0 + (-9.81) (3.5)
-34.3 m/s (Answer)
Answer:
i think ability to reproduce
The correct option is (D) the attraction between water molecules.
The attraction between water molecules cause surface tension.
<h3>What causes the water molecules' surface tension?</h3>
- Cohesive interactions between the liquid's molecule's cause the surface tension to develop. The molecules at the center of the liquid are surrounded by other molecules on both sides.
- The net force is zero because molecules are tugging on one another equally in all directions. In contrast to the majority of the liquid, the liquid molecules at the interface only have half as many nearby molecules.
- This results in a net inward pull toward the liquid and a stronger association of the molecule with the molecules on either side of it. The force preventing the surface from breaking is surface tension.
