The astronomer who discovered the dwarf planet Eris suggests there might be another object far beyond the Kupier belt. If this P
PolarNik [594]

These objects would be classified as extreme trans Neptunian object (ETNO).

Explanation:

ETNO’s are the objects lying beyond the planet Neptune and orbiting the Sun. They follow a highly eccentric path which is tilted. ETNO has been grouped into three major according to their respective perihelia.  

Within this region (beyond Neptune’s orbit), a hypothetical planet has been discovered. It was discovered following its gravitational effect on the other objects of Kuiper Belt (region beyond the orbit of the Neptune- the last planet of our Solar system)

The Planet is assumed to be around 2 times the Earth’s size and around 10 times heavier than Earth.

As part of your daily workout, you lie on your back and push with your feet against a platform attached to two stiff springs arr
zmey [24]

Answer:

F =1490.9 N

Explanation:

given,

work done = 82 J

compression length = 0.220 m

for parallel combination

k_{eq}= k_1+k_2

         = 2 k

work done

w = \dfrac{1}{2}k_{eq}x^2

k_{eq} = \dfrac{2W}{x^2}

k_{eq} = \dfrac{2\times 82}{0.22^2}

k_{eq} =3388.43 N/m

force =

F = kx

F = 3388.43 ×0.22

F =745.45 N

the additional work done

final potential energy = \dfrac{1}{2}k_{eq}(2x)^2

                                    = 4 W = 328 J

the additional work = 328 - 82 = 255 J

maximum force

F = k × 2x

F = 2×745.45

F =1490.9 N
