Answer:

The word that fills the blank is:

Even though earth has less mass than the sun, the moon orbits earth because it much nearer to it.

Explanation:

Two very important factors intervene to be affected by the gravity of a body:

body mass.
The distance from the celestial body.

Although the sun has a distance many times greater than Earth (1,989 × 10 ^ 30 kg and 5,972 × 10 ^ 24 kg respectively), the moon orbits the Earth since the distance between these two is 384,400 km, a distance very small when compared to the distance to the sun which is approximately 149.6 million km.

Even though the Earth has less mass than the Sun, the moon orbits Earth because it’s much nearer to it.

Explanation :

The fact is that the Moon orbits both the Sun and the Earth. On looking at the orbit of the Moon, it orbits in the same manner the way Earth does, but in a Spiro graph pattern along with orbiting the Earth with a small wobble to it.

Since the Sun has greater distance from the Moon as compared to the Earth (around 400 times), the gravity of Earth draws better impact on the Moon.

The escape velocity of the Moon is about 1.2 km/s at the distance from the Earth which is not sufficient to get ripped away from the Earth.

Hence, the moon orbits the Earth along with orbiting the Sun together with the Earth, but seems as if it only orbits the Moon.

Name the four fundamental (basic) forces.

lorasvet [3.4K]

From what I have been told, the four basic forces regarding physics are the strong or powerful force, a gravitational force, an electromagnetic force, and a weak force. The strong force binds nuclei. Weak forces take care of nuclear decay. Electromagnetic forces exists when two or more objects have an electric charge like a magnet or positive and negative, negative and positive And gravitational forces is just gravity. What holds us down.

What are the 3 base units of measurement ?

Artist 52 [7]

In the SI (International, metric) system of measurement, they are the Kilogram of mass, the Meter of length, and the Second of time.

With mass, length, and time, you can combine them in enough ways to measure ALMOST everything that can be measured in the physical world, like speed, velocity, acceleration, momentum, area, volume, force, energy, pressure, etc.

'Almost'. You still need a few more to wrap things up. The other quantities (and their SI units) are: Electric charge (the Coulomb), temperature (the Kelvin), amount of a substance (the Mol), and luminous intensity (the Candela). You can't build these with only mass, length, and time.

According to the solar nebular theory, a supernova triggered the collapse of a nebula, which began the formation of clumps of ga

tekilochka [14]

The answer would be sun and planets. The reason is because when there was pressure in the nebula collapse it became hotter and created a star also know as the sun which also created planets with it.

Explanation:

The work of the electric force does not depend on the trajectory or the path taken. Regardless of trajectory a and b we have the following
