Reactivity is the ability to react with other substances/(the answer is reactivity)
Explanation:
A concave mirror can form real, inverted images of various sizes and virtual, erect and enlarged images whereas a concave lens forms only virtual, errect and diminished images.
Answer:
Cat with 6 kg sitting on a 30 meter hill has greater potential energy.
Explanation:
gravitational potential energy (J) = mass (kg) × gravitational field × height (m)
<h3 /><h3><u>Note</u>:</h3>
gravitational field in Earth is 10 N/kg = <u>fixed unit</u>
<h3 /><h3><u>Given</u>:</h3>
1st Cat: 4 kg
2nd Cat: 6 kg
Both of their height is 30 meters.
<h3><u>Solve for g.p.e</u>:</h3>
1st cat = mgh = 4 × 10 × 30 = 1200 Joules
2nd cat = mgh = 6 × 10 × 30 = 1800 Joules
<span>It is true that all nuclear energy results in
the rapid release of energy, such as in atomic bombs. <span>A process wherein the atom’s nucleus
is further divided into two nuclei, that is, fission products, is called
nuclear fission. This happens when the nuclei of radioactive elements (e.g.
Uranium or Plutonium isotopes) are able to attract neutrons. Because these
isotopes’ nuclei are unstable, an addition to their energy causes them to
divide into new pieces of neutron. In nuclear reactors, fission occurs when the
power plant gathers heat from a steam in a physical process. Nuclear reactors
are designed to sustain nuclear chain reactions.</span></span>
