Answer:
Explanation:
Information we have:
velocities:
initial velocity: 
(starts from rest)
final velocity: 
time: 
Since we need the answer in 
, we nees to convert the speed to meters per second:
We find the acceleration with the following formula:
substituting the known values:
the acceleration is 10.07
<h2>Answer: protons and neutrons.
</h2>
The atomic nuclei of almost all elements consist of protons and neutrons.
The nucleus of an atom has very small dimensions. However, it <u>occupies its central part and concentrates more than 99% of its total mass.
</u>
It is in the nucleus that the protons (positive charge) and neutrons (neutral charge) are found.

Answer:
Δu=1300kJ/kg
Explanation:
Energy at the initial state
Is saturated vapor at initial pressure we have
Process 2-3 is a constant volume process
The overall in internal energy
Δu=u₁-u₃
We replace the values in equation
Δu=u₁-u₃
Δu=1300kJ/kg
Answer:
See Explanation
Explanation:
The principle of conservation of energy states that; energy can neither be created nor destroyed but is converted from one form to another.
In view of this principle, Ella can not be correct when she says that a lot of energy has disappeared. The use of the term "disappeared" connotes the idea that the energy no longer exists which does not happen.
Hence, energy can not "disappear" from hot water rather the energy in the water may be transferred to the surroundings.
