Option B
Neptune, Uranus, Saturn, Jupiter, Mars, Earth, Venus, Mercury correctly describes the usual order of planets inward toward the sun
<u>Explanation:</u>
Our solar system continues much considerably than the eight planets that revolve around the Sun. The position of the planets in the solar system, commencing inward to the sun is the accompanying: Neptune, Uranus, Saturn, Jupiter, Mars, Earth, Venus, Mercury.
Most next to the Sun, simply rocky material could resist the heat. For this logic, the first four planets: Mercury, Venus, Earth, and Mars are terrestrial planets. The four large outer worlds — Jupiter, Saturn, Uranus, and Neptune: because of their enormous size corresponding to the terrestrial planets. They're also frequently composed of gases like hydrogen, helium, and ammonia preferably than of rocky surfaces.
Answer:
the required value is 
Explanation:
Given that,
mass, m = 1kg
spring constant k = 21N/M
damping force = 

By Newtons second law ,
The diffrential equation of motion with damping is given by

substitute the value of m =1kg, k = 21N/M, and 


suppose the equation of the form
,
and the auxilliary equation is given by

The general solution for the above differential equation is

Derivate with respect to t

(a)
since time is 0 then mass is one meter below
so x(0) = 1
Also it start from rest , that implies , velocity is 0 and time is 0

substitute the initial condition


Solve the above equation to get C₁ and C₂

substitute for C₁ and C₂ in general solution

Thus the required value is 
The first one is electrical energy
Answer:



- Our final answer is 15 kg .
