A:we<em><u> can</u></em><em><u> </u></em><em><u> see birds, drones, airplanes all because of gravity. If you want to get bigger, we can see our Sun and planets revolve because of gravity, orbital mechanics and light.</u></em>

B:With<em><u> less gravity, it is harder to keep your body strong. If the Earth's gravity is lost, all items held to the Earth's surface by gravity would float away. That includes the atmosphere, water, people, cars and animals. If an object were secured strongly to the Earth, it would probably remain attached.</u></em>

<em><u>Hope</u></em><em><u> </u></em><em><u>it</u></em><em><u> </u></em><em><u>will</u></em><em><u> </u></em><em><u>be</u></em><em><u> </u></em><em><u>helpful</u></em><em><u> </u></em><em><u>to</u></em><em><u> </u></em><em><u>you</u></em><em><u>.</u></em><em><u>.</u></em>

Mark all that apply. The action and reaction forces referred to in Newton's third law: are opposite in direction act upon differ
PSYCHO15rus [73]

The action and reaction forces referred to in Newton's third law are <u>opposite in direction and act upon different objects.</u>

In science, more specifically in the science classical mechanics, Newton's laws are principles that show the forces that act upon objects in motion. The first law speaks of momentum, the second of acceleration, and the third law states that for every action, there is an<u> equal and yet opposite </u>reaction.

Newton's third law may be confusing at first glance, but what it means is that the action and reaction forces are opposite in direction and act upon different objects, meaning that when one object applies force to another, the second will in-turn apply the same force back, whichever object is most resistant to these forces will be the one that moves the other.

Fantom [35]

Answer: 77.0J

Explanation:

The magnetic field is given as 4.40T

Since the volume is not given, we assume that the volume is 10.0cm³

We need to find the magnetic field energy in this volume.

The energy density is:

u = B²/2u•

u• is given as 4π × 10^-7 T.m/A

Using this formula we substitute

u = B²/2u• = (4.40 T)²/ 2(4π × 10^-7 T.m/A) = 7.704 × 10^6 J/m³

The energy is equal to the energy density multiply by the volume. You get;

U= uV = (7.704 × 10^6 J/m³) × (10.0 × 10^6m³) = 77.0J
