Answer:
answer is option C
Explanation:
i.e.
energy required to make the molecules collide so that reaction can occur.
The motivation behind why the vertical stature of the stairs is the main thing measured is that it uncovers to us how much gravity is up against the individual and their weight, so we require this data to decide how much vitality and power we have to get up the stairs.
<h2>
Answer: C. Kinetic energy</h2>
Explanation:
Heat is energy in transit, in fact it is a transfer of thermal energy from one body to another.
So, when a metal is heated is because we have two bodies with different temperatures and thermal energy is transferred from one body to another, implying a high speed and kinetic energy in the particles involved (electrons in this case).
This is because the kinetic energy of a particle is that energy it possesses due to its movement, and according to the first principle of thermodynamics, there is a relationship between heat and movement, since the metal is composed of particles that are in motion (to a certain extent).
In this way, with the increase of the temperature of the metal, there is an increase of the kinetic energy of its free electrons with a gain of velocity (movement), therefore a gain in kinetic energy.
Answer:
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
Explanation:
The system formed by the masses is isolated so its angular momentum is conserved
initial instant, which throws the mass with angular velocity o and radius ro
L₀ = I w₀
final instant. When the mass has a radius r and an angular velocity w
L_f = I_f w
Lo = l_f
I₀ w₀ = I_f w_f
let's analyze this result
* angular momentum throughout the lar process is conserved throughout the entire process
* the angular velocity decreases as the radius of the pizza increases
