<h2>
Answer:When electrons absorb or emit quantized units of energy in the form of photons.</h2>
Explanation:
When a electron is collided with a photon with exactly the same energy it would require to get to any of the farther orbits,electron transition takes place to an orbit depending on the energy of the photon.
When electrons emit exactly the same amount energy that is difference between the current energy level and the new level,then the electron makes a transition to the new level.
Answer:
5.71 N/m
Explanation:
From the question given above, the following data were obtained:
Extention (e) = 3.5 m
Force (F) = 20 N
Spring constant (K) =?
From Hooke's law,
F = Ke
Where :
F => is the force applied
e => is the extention caused by the force
K => is the spring constant
With the above formula, we can obtain the spring constant of the spring as follow:
Extention (e) = 3.5 m
Force (F) = 20 N
Spring constant (K) =?
F = Ke
20 = K × 3.5
Divide both side by 3.5
K = 20 / 3.5
K = 5.71 N/m
Thus, the spring constant of the spring is 5.71 N/m
Answer:
a) 60 N
b) 860 N
Explanation:
Given that,
= 100 kg
= 20 kg
= 8.0
= 3.0
a) By Newton's Law,
∑
∑
Hence,
b) By Newton's Law
∑
Hence,
Net force acting on 100 kg mass,
