An electric kettle. The input energy is 10 Joules. The useful output energy is heat 9Joules. Wasted energy is sound 1 Joules.​

Answers

Answer:

Efficiency = 90 %

Wasted energy = 10 %

Explanation:

Since we have the input energy and useful output energy of the electric kettle, the only thing we are required to calculate here is its efficiency. This is gotten from

E = useful output energy/input energy × 100

E = 9/10 × 100 = 90 %

The percentage of wasted energy is

W = wasted energy/input energy × 100

W = 1/10 × 100

W = 10 %

All nuclear energy results in the rapid release of energy, such as in atomic bombs. a. True
b. False

Answers

It is true that all nuclear energy results inthe rapid release of energy, such as in atomic bombs. A process wherein the atom’s nucleusis further divided into two nuclei, that is, fission products, is callednuclear fission. This happens when the nuclei of radioactive elements (e.g.Uranium or Plutonium isotopes) are able to attract neutrons. Because theseisotopes’ nuclei are unstable, an addition to their energy causes them todivide into new pieces of neutron. In nuclear reactors, fission occurs when thepower plant gathers heat from a steam in a physical process. Nuclear reactorsare designed to sustain nuclear chain reactions.

Answer:

FALSE

Explanation:

verified answer***

Nuclear energy is released from an atom through one of two processes: nuclear fusion or nuclear fission. In nuclear fusion, energy is released when the nuclei of atoms are combined or fused together. But isn't rapidly release
