Answer:

Please find the answer in the explanation

Explanation:

Given that Force affects the body and results in different changes.

The grid that has the words related to the effects of force are :

a) Force could be a push or a pull.

c) Force has magnitude as well as direction.

e) Force acting on an object may cause a change in its state of motion or a change in its shape.

f) A force can act on an object with or without being in contact with it.

$E_i-E_f=-17.94 \times 10^9 \mathrm{~J}-\left(-18.30 \times 10^9 \mathrm{~J}\right)=3.60 \times 10^8 \mathrm{~J}$.

The most effective forces on the object are the backward force of air resistance relatively very small in magnitude, and the force of gravity. Because the spiral path of the satellite is not perpendicular to the gravitational force, one element of the gravitational force pulls forward. at the satellite to do fantastic work & make its speed increase.

<h3>What is called gravitational force?</h3>

Gravity, additionally referred to as gravitation, is a force that exists amongst all material gadgets withinside the universe. For any objects or particles having nonzero mass, the force of gravity tends to draw them in the direction of each other. Gravity operates on objects of all sizes, from subatomic particles to clusters of galaxies.

Airida [17]

Answer:

the resulting angular speed after she pulls her hand inwards in (rad/s)  is  27.02 rad/s

Explanation:

Given that :

the initial angular speed \omega_1 = 1.9 \ \ rev/s

Initial rotational inertia I_1 = 12.00 \ \ kg.m^2

Final angular speed \omega_2 = ???

Final rotational inertia I_2 = 5.3 \ \ kg.m^2

According to conservation of momentum :

Initial momentum = final momentum

I_1 \omega_1 = I_2 \omega_2

\omega_2 = \frac{I_1 \omega_1}{I_2}

\omega_2 = \frac{12.00*1.9}{5.3}

\omega_2 = 4,3 rev/s

To rad/s ; we have:

1  \   rev/s = 2 \pi \ \  rad/s

\omega_2 = 4.3 * 2 \pi \ \  rad/s

\omega_2 = 27.02  \ \ rad/s

Therefore the resulting angular speed after she pulls her hand inwards in (rad/s) = 27.02 rad/s
