Answer:
Detection of x-rays from a binary star undergoing mass exchange, where mass of component star can be determined.
:
change in potential energy , ∆Ep = 156.8Joules
Explanation:
Given;
Mass of object , m = 2.0 kg
Heights ; h₂ = 5.0m
h₁ = - 3.0m
To obtain
the change in potential energy, ∆Ep = ?
But,
∆Ep = mg∆h
Where;
m is the mass of the object (kg)
∆h = h₂ - h₁ is the change in height (m)
g is the acceleration due to gravity ( 9.80 m/s²)
Therefore,
the change in potential energy, ∆Ep = 2.0 × 9.80 × ( 5 - (- 3))
=156.8 joules
Each one of the elements in group 13 has three electrons in the outer shell of their nuclear structure
I believe the correct answer is false. The behaviors that light exhibits are reflection, refraction, diffraction but not polarization, and dispersion. Light<span> behaves as a wave - it undergoes reflection, refraction, and diffraction just like any wave would. Hope this answers the question.</span>
