y Laplace in this formula?
Ise the formula given by Laplace to explain why the speed of sound in a air
i) is independent of pressure
ii) increase with temperature.

explanation:

object 2 because all the other ones are wrong

measure their densities same density, same sub

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
