(150 meters) / (18 seconds) = 8.33 meters per second
The potential energy of any object depends on its mass as well as its height off the ground.
Potential energy = mass x gravity x height.
We don't have enough information to compare the potential energies of these two objects because we don't know their masses.
Explanation:
When a person is standing still, the forces acting on them (weight force pulling down and normal force pushing up) are equal and opposite, so the net force is balanced. So the person will continue to be at rest, unless the net force becomes unbalanced.
When a person falls with a parachute, the forces acting on them (weight force pulling down and air resistance pushing up) are equal and opposite, so the net force is balanced. So the person will continue to fall at the same speed until the net force becomes unbalanced.
S = d/t, s = 120, d = 2000, t = ?
Input the values,
120 = 2000/t
Make t the subject of the formula by cross multiplying, Therefore,
120t = 2000
Divide both sides by 120
t = 16.7hrs to 1 decimal place.
If you're asked to convert it, you can.
Answer:
The correct answer is detritic rocks.
Explanation:
Sedimentary rocks are rocks formed by the accumulation of sediments, particles of various sizes that are transported by water, ice or wind, which are subjected to physical and chemical processes, resulting in consolidated materials.
Sedimentary rocks formed from the accumulation of mineral deposits and rocks from erosion and deposited by gravity are called detritic rocks.
Have a nice day!
