Answer:
A. Elements with intermediate numbers of valence electrons are the last chemically stable.
Explanation:
Kinetic energy is the energy of the motion.
This is because the kinetic energy can be calculated by using the formula,
K.E.=1/2 mv^2
where, v is the velocity of moving body i.e. the body is in motion.
Physics is known as the fundamentals of science, as all the branches of science, whether it is biology, chemistry, ecology, botany, environmental science, geology, geography, and more all follow the laws of physics, such as laws of thermodynamics, etc. Chemistry is existent because of physics due to the Conservation of mass. Once you get to a much deeper level of science, you will notice that all the fields of science start to blend together and all add up to one huge painting!
Answer:
Explanation:
As the final Kinetic energy is zero or less than initial kinetic energy, the collision must be inelastic.
In Inelastic collision both the bodies must stick together as final velocity is zero for both the bodies.
To conserve the momentum, momentum associated before the collision of first must be equal and opposite to the momentum associated with the second ball.
i.e.
I think you would be using a topographic Map, So the answer should be A
