A. Nebula . Is The Answer !
Answer:
K
Explanation:
The Heisenberg uncertainty principle is
Δx Δp ≥ h' / 2
h’ =
The kinetic energy of a particle is
K = ½ m v²
p = mv
v =
substitute
K =
from the uncertainty principle,
Δp =
we substitute
K =
Answer:
Explanation:Newton.s law of cooling states that the rate of cooling of an object is proportional to the difference between its own temperatures and temperature of its surroundings. Mathematically,
where is the heat transfer
is heat transfer coefficient
is the heat transfer surface area
is the temperature of the object's surface
is the temperature of the surroundings
