Answer:
v = √ k e²/m r
Explanation:
From the classical point of view the force between the nucleus and the electron is electrostatic
F = q E
q = e
we apply Newton's second law
F = m a
where the centripetal accelerations
a = v² / R
we substitute
e E = m v² / r
v² = ( e/m E r)
the electrioc field is
E = k q/r²
v² = e/m k e/r
v = √ k e²/m r
The heat is exchanged when two different temperature objects come in contact. The energy gained by an ice block is 2.3 Joules.
<h3>What is temperature?</h3>
Temperature is the degree of hotness and coldness of the object.
A 7g block of ice was added to a coffee cup full of 103.4 grams of water. The water had an initial temperature T₁ = 24.5 C and a final temperature T₂ = 19.2 C after all the ice had melted.
Heat lost by water = Heat gained by ice
Qgain = ms(T₂ -T₁ )
Substituting the value for mass of water m =103.4 g= 0.1034 kg , specific heat of water s = 4.18 kJ/kg and temperature values, we get
Qgain = 0.1034 x 4.18 x (24.5 - 19.2)
Qgain = 2.3 Joules
Thus, the energy gained by an ice block is 2.3 Joules.
