Well simple the warm water then replaces the cold current that sinks to the ocean floor.

What is the smallest unit of a substance that keeps all of the physical and chemical properties of that substance?
Molecules is the smallest unit of a substance that keeps all of the physical and chemical properties of that substance. It is a group of atoms bounded together, and it can participate in a chemical reaction/
Hope I helped (:
Have a great day!
Answer:
601 nm
Explanation:
Energy of photon having wavelength of λ nm
= 
eV
Energy of 249 nm photon
=
=4.996 eV
Similarly energy of 425nm photon
=
=2.927 eV
Difference = 2.069 eV.
This energy will give rise to another photon whose wavelength will be
λ = 
= 601 nm.
Answer:
The time taken for the train to cross the bridge is 9.01 s
Explanation:
Given;
length of the train, L₁ = 90 m
length of the bridge, L₂ = 0.06 m
speed of the train, v = 10 m/s
Total distance to be traveled, = L₁ + L₂
= 90 m + 0.06 m
= 90.06 m
Time of motion = Distance / speed
Time of motion = 90.06 / 10
Time of motion = 9.006 s ≅ 9.01 s
Therefore, the time taken for the train to cross the bridge is 9.01 s
