<u>Answer:</u> The average kinetic energy of helium atoms is 
<u>Explanation:</u>
To calculate the average kinetic energy of the atom, we use the equation:
where,
K = average kinetic energy = ?
k = Boltzmann constant = 
T = temperature = 
Putting values in above equation, we get:
Hence, the average kinetic energy of helium atoms is
1: Weather has a somewhat unpredictable pattern.
2: They can misinterpret the pattern of weather that looks like snow.
3: If they predict it early then the weather can change making there interpretation wrong.
Hope that helps a little bit. Please don’t report me I tried.
Answer:
28 J
Explanation:
Mechanical energy is the sum of kinetic and potential energy in an object that is used to do work. In other words, it is energy in an object due to its motion or position, or both.
In physics, mechanical energy (Emech) is the energy associated with the motion and position of an object usually in some force field.
Therefore:
ME = KE + PE = 25 + 3 = 28 J
Explanation:
Distance = Total path length = 35m + 35m = 70m
Displacement = Final - Initial position = 0m
