Answer:
Kinetic Energy and Potential Energy
Explanation:
When an object is in motion(ie.moving), it has kinetic energy. Energy stored in an object due to position and state, is called potential energy.
A. True. The ozone layer is very critical to our health.
Salad is biotic, it is made from plants and plants are alive.
biotic means alive
abiotic means not alive
Answer:
Not affected.
Explanation:
Kinetic energy of the dominoes not affected if the first domino did not hit the second one because no kinetic energy is lost due to no collision. If the first domino hit the second one, its kinetic energy decreases and changes in other form of energy such as heat and sound energy etc. But when there is no collision occur, then there is no change in the kinetic energy of dominoes.
Answer:
5
Explanation:
mass number=no of protons +no of neutron
mass number-atomic number=no of neutron
12-7=5
