-- Energy is never created or destroyed.

-- No energy is added to the pendulum during its swing.

-- If we ignore air resistance and friction, then no energy is lost
from the pendulum during its swing.

-- Therefore the total energy of the pendulum must be constant.

-- Any potential energy lost at any point in the swing
must show up as kinetic energy.  If it had 484J at the top,
then it'll have 484J at the bottom.

Morgarella [4.7K]

Answer: 9.9%

Explanation: efficiency = (work output /work input) × 100

Note that, 1 kilocalorie = 4184 joules, hence 22kcal = 22× 4184 = 92048 joules.

Work output = 9200 j and work input = 92048 j

Efficiency = (9200/92048) × 100 = 0.099 × 100 = 9.9%

What is the relationship between the atoms of elements,its isotopes and its ions
klasskru [66]
An element refers to a collection of atoms having the same number of protons and electrons (an atomic number). In each element there is a different atomic number due to a different amount of protons in the nucleus.

An isotope is a variation of an element that contains a different number of neutrons, therefore adding weight to the atom.

An ion is a charged atom, and its charge shows how many electrons it needs to gain or lose in order to become stable.
