Pushing a wheelbarrow uphill requires more energy because you are working against gravity. Gravity pulls the wheelbarrow back down, so you need to exert a greater force to overcome this resistance and move the wheelbarrow upward. On ground level, you are not working against gravity to the same extent, so less energy is required.

What is the energy required to excite an electron from the ground state to an excited state with an energy level of 13.6 eV?
The energy required to excite an electron from the ground state to an excited state with an energy level of 13.6 eV is 13.6 electron volts.
What is the potential energy at the ground?
The potential energy at ground level is typically zero, as the reference point for potential energy calculations is often set at ground level. This means that any object at ground level would have zero potential energy due to its height above the ground.
What is the state when all electrons of an atom are in the lowest possible energy levels?
whenever they are in there most stable state , then they are at their lowest energy level. as u provide energy , they get excited and then upgrade to further energy level . and due to loss of energy , they regain earlier positions.
Can the gravitaional potential energy of an object be negative?
Yes. Any object that is above a reference level has positive potential energy; anything below that reference level has negative potential energy. For example, if the chosen reference level is the ground level, anything below the ground level has negative potential energy. Please note that the choice of reference level is arbitrary. What matters is the DIFFERENCE in potential energy between two positions - and that doesn't change, whether you choose (for example) the ground level, or some other level, as a reference level.
What level that contains the least amount of available energy is composed of?
The ground state, which is the lowest energy level of an atom, contains the least amount of available energy. Electrons in the ground state have the lowest possible energy and are closest to the nucleus.

What form of energy does an elevator have?
If it is above a chosen reference level (e.g., ground level), it has potential energy. While it is moving, it has kinetic energy.
What level that contains the least amount of available energy is composed of?
The ground state, which is the lowest energy level of an atom, contains the least amount of available energy. Electrons in the ground state have the lowest possible energy and are closest to the nucleus.
How can you tell that a high diver has gravitational potential energy?
If an object is above ground level, it has positive gravitational potential energy. (This assumes you define ground level to be zero - actually, you can define any level to be zero.)
What is the highest energy level in an atom of strontium in its ground state?
In its ground state, an atom of strontium has the electron configuration of [Kr] 5s². The highest energy level is n=5, which corresponds to the outermost electrons in the 5s subshell. Thus, the highest energy level in a ground state strontium atom is 5.
Besides the earth what things have a gravitational pull?
Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.Any object that is above the reference level (usually taken as ground level) has potential energy, according to the formula PE = mgh.
What is the energy required to move an electron up an energy level called?
Ionisation energy, or alternatively quantum energy.
How much energy is required to ionize a hydrogen atom containing an electron in the n4 level?
The energy required to ionize a hydrogen atom with an electron in the n4 level is 0.85 electron volts.
