Answer:
Option D
Explanation:
Jupiter is made almost totally from hydrogen and some hydrogen compounds. It may have a solid hydrogen core, then a liquid hydrogen layer, then a gaseous layer.
It is not known if Jupiter has a solid surface, or even a liquid surface. We measure Jupiter's diameter from the top of its gas layer.
The core is often described as rocky, but its detailed composition is unknown, as are the properties of materials at the temperatures and pressures.
The presence of a core during at least part of Jupiter's history is suggested by models of planetary formation that require the formation of a rocky or icy core massive enough to collect its bulk of hydrogen and helium from the protosolar nebula. Assuming it did exist, it may have shrunk as convection currents of hot liquid metallic hydrogen mixed with the molten core and carried its contents to higher levels in the planetary interior. A core may now be entirely absent, as gravitational measurements are not yet precise enough to rule that possibility out entirely.
Answer:
Answer in below and plz mark me as brainlist plz
Explanation:
The rate of change of momentum =tm(v−u) Rate of change of momentum = force applied. Force∝tm(v−u) Velocity is the rate of change of displacement and acceleration is the rate of change of velocity. Impulse is a change in momentum
Explanation:
The energy stored in an elastic objects as a result of deformation is called elastic potential energy. The energy stored in a spring is given by :
Where
k = spring constant
x = compression or stretching in an spring
While gravitational potential energy is given by :
PE = mgh
where
m = mass
g = acceleration due to gravity
h = height from ground
So, the factor affecting elastic potential energy but not gravitational potential energy is " spring constant ".
Answer: Solar Day
Explanation: As explained above, a Solar Day is the time it takes to the earth to rotate between to Solar Position. This time is taken as reference to calculate the day, so this times equals to 24 hours.}
However the Sideral Day is the time on which the Eart rotates between two consecutives position on a distant star. The Sideral day is shorter because both Earth Rotanting Movements are counter-clockwise.
The Earth moves around the sun and around his own axis. Because of this, the earth after doing a full rotation, needs to compensate a extra degree to face the sun at the same spot, so the movement is longer.
