Answer:
Explanation:
Assume the stone consists of basalt, which has a density of 3.0 g/cm³.
Answer: (2) > (1) > (3) > (4)
Explanation:
(1) a +1 charge and a -1 charge separated by 200 pm:
The potential energy in this case will be,
(2) a +1 charge and a +1 charge separated by 100 pm:
The potential energy in this case will be,
(3) a +1 charge and a -1 charge separated by 100 pm:
The potential energy in this case will be,
(4) a +2 charge and a -1 charge separated by 100 pm:
The potential energy in this case will be,
So, the order from <u>highest</u> potential energy <u>to lowest</u> potential energy is:
(2) > (1) > (3) > (4)
Only if a force acts upon it, it can move.
Answer:
θ = (7π / 3) rad
Explanation:
given,
displacement of simple harmonic motion along x-axis
equation is given as
x = 5 sin (π t + π/3 )
general equation of simple harmonic motion
x = A sin θ
θ is the phase angle
θ = π t + π/3
at t = 2 s
Phase of the motion at t =2 s is θ = (7π / 3) rad
