Now suppose that the Earth had the same mass and radius as it currently does, but all of the mass was concentrated into a thin (
KiRa [710]

Answer:

The force of gravity at the shell will be extremely great on me due to the huge mass collapsed into the small radius.

<em>At the center of the shell, the gravitational forces all around should cancel out, giving me a feeling of weightlessness; which will be a lesser force compared to that felt while standing on the shell.</em>

<em></em>

Explanation:

For the collapsed earth:

mass = 5.972 × 10^24 kg

radius = 1 ft

according to Newton's gravitation law, the force of gravity due to two body with mass is given as

Fg = GMm/R^{2}

Where Fg is the gravitational force between the two bodies.

G is the gravitational constant

M is the mass of the earth

m is my own mass

R is the distance between me and the center of the earths in each case

For the case where I stand on the shell:

radius R will be 1 ft

Fg = GMm/1^{2}

Fg = GMm

For the case where I stand stand inside the shell, lets say I'm positioned at the center of the shell. The force of gravity due to my mass will be balanced out by all other masses around due to the shell of the hollow earth. This cancelling will produce a weightless feeling on me.

Which statement best defines inertia? An object's motion is unaffected by any external forces acting upon it. An object responds
svetoff [14.1K]

Answer:

An object responds to a force by tending to move in the direction of that force

Explanation:

The inertia of a body can be defined with the help of Newton's second law

          F = m a

Where F is the applied force, a is the acceleration of the body and m is the mass

the force and the acceleration are vectors that point in the same direction and m is a scalar constant that relates the two vectors, this scalar constant is called masses and it measures the resistance of the bodies to the change of motion.

From the previous statement we see that the statement that best describes inertia is:

An object responds to force by tending to move in the direction of the force.
