They enable us to dig deeper into the electron configurations by making us focus on electrons' quantum nature
Answer:
The ball has kinetic energy
the kinetic energy is 945 J
Explanation:
The answer is B. good luck :)
Infrared contains the least energy and ultraviolet contains the most energy. The energy of a wave is inversely proportional to its
A string with linear density 0.500 g/m.
Tension 20.0 N.
The maximum speed 
The energy contained in a section of string 3.00 m long as a function of
.
We are given following data for string with linear density held under tension :
μ = 0.5 
= 0.5 x 10⁻³ 
T = 20 N
If string is L = 3m long, total energy as a function of
is given by:
E = 1/2 x μ x L x ω² x A²
= 1/2 x μ x L x 
= 7.5 x 10⁻⁴ 
So, The total energy as a function of
= 7.5 x 10⁻⁴
