Answer:
2.13 s
Explanation:
Hi!
At t = 0s the rocket is at rest in its platform, so the intial speed is zero. I f the acceleration is A, then the height Y, and the speed V are:
We nedd to find time T during which the rocket engine provides upward acceleration. We know that:
With these 2 equations we can find A and T (dropping units for simplicity):
The sequence that correctly lists earthquake waves from strongest to weakest is : ( C ) P waves -- S waves-- Surface waves
<h3 /><h3>Types of earthquake waves </h3>
P waves are the strongest waves because they move more rapidly inside the incompressible earth core sending its energy at a hazardous rate, while the S waves are slower and produces vertical movement of the earth surface.
The weakest waves are the S waves which sweeps across the outer surface of the earth and they are also the slowest of all the waves.
Hence we can conclude that the sequence that correctly lists earthquake waves from strongest to weakest is P waves -- S waves-- Surface waves

Answer:
Explanation:
The total energy at all times is equal to the sum of kinetic and potential energy.
Eu = Ep + Ek
If an object has reached a finite height point and is stationary, then the potential energy is maximum (100 J) and the kinetic energy is equals to zero.
If the same object started to fall before the impact on the ground itself, the kinetic energy is maximum (100 J) and the potential energy is minimum ie zero.
