Where is the Temperature bud?
He would have potential, he hasn’t gone down the mountain yet so he remains potential
Answer:
3 kg
Explanation:
Momentum before = momentum after
m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂
After jumping on the skateboard, the student and the skateboard have the same velocity, so v₁ = v₂.
m₁u₁ + m₂u₂ = (m₁ + m₂) v
(47.4 kg) (4.2 m/s) + m (0 m/s) = (47.4 kg + m) (3.95 m/s)
m = 3 kg
Answer:
B. They are the electrons that interact with other atoms.
Explanation:
Valence electrons are the electrons in the outermost shell of an atom. These electrons are used by atoms to form bonds with other atoms during chemical bonding.
- So, the basis by which atoms interacts with one another is through the valence electrons.
- Without the valence electrons, atomic combination to form compounds would not be possible.
- Valence electrons are the most loosely held electrons and they have the lowest ionization energy.
