Electrons in an iron atom (or in any atom) cannot settle all together into the lowest energy state because of Pauli exclusion principle: this principle states that two or more identical fermions (and so, electrons included) cannot occupy the same quantum state of a system at the same time.

The transportation industry is no stranger to the manipulation of everyday physics. Cars and trains utilize the wheel, which provides a smooth, steady motion.

The ears hear sounds which occur through the movement of air molecules, and the chemistry that drives all of biology depends on the physics of energy and molecules. Every day, for example, plants absorb sunlight, water, and carbon dioxide, creating glucose and releasing oxygen as a byproduct.

Inessa [10]

Answer:

v₁ = -0.8087 m / s

Explanation:

To solve this problem we can use the conservation of momentum, for this we define a system formed by the man, the skateboard and the brick, therefore the force during the separation is internal and the momentum is conserved

Initial instant. When they are united

p₀ = 0

Final moment. After throwing the brick

$p_{f}$ = (m_man + m_skate) v1 + m_brick v2
