The formula used to find potential energy is <em>P.E. = M * G * H</em> (P.E. is potential energy, M is mass, G is gravitational pull, and H is height). So the answer to your question is <em>5 * 9.8 * 2</em>, which equals 98.
Answer:
Ice is water in solid phase, in this phase, the particles are very close together and relatively in fixed positions.
As the temperature starts to increase (thermal energy), also does the kinetic energy of the particles (so we have a change from thermal energy to kinetic energy), so they start to move "more", and the position of the particles starts to be less "fixed". There is a point where the particles have enough energy, and this point is where the phase of the water changes from solid to liquid phase (the fusion point). After this point the water can not hold his shape, and takes the shape of the container where it is.
Answer:
Explanation:
Mass of the helium gas filled inside the volume of balloon is given as
now total mass of balloon + helium inside balloon is given as
now we know that total weight of balloon + cargo = buoyancy force on the balloon
so we will have
A
Excitation to a higher energy state requires energy which is absorbed from the electromagnetic waves applied.
