Question

a model shows that the moon has grown since twice its size yet it remains in the same place in one to two sentences explain how this would impact the gravity between Earth and the Moon

Answer 1

If the moon has grown twice its size while remaining in the same place, it would suggest that the mass of the moon has significantly increased. Consequently, the gravitational force between the Earth and the Moon would become stronger.

Answer 2

a student wants to draw a scale model of the solar system in 3 to 4 sentences, or bullet points explain what steps should be taken to create this model

Answer 3

1. Determine the scale: Choose a scale that allows you to accurately represent the sizes and distances between planets and the Sun. For example, if you use a 1:100 scale, then 1 cm on the model would represent 100 cm (or 1 meter) in reality.

2. Select a suitable object for the Sun: Find a large spherical object like a basketball or a beach ball to represent the Sun. Ensure that its size corresponds to the chosen scale.

3. Create planet representations: Choose various objects (marbles, beads, or small balls) to represent each planet. Adjust their sizes according to the scale chosen, keeping in mind the relative sizes of planets.

4. Position the planets: Place the Sun at the center and position the planet models at appropriate distances from it. Use accurate measurements or refer to online resources for the correct average distances between planets.

Note: Depending on the scale and the accuracy desired for the model, additional steps may be involved, such as including moons, asteroids, or dwarf planets.

Answer 4

nvm answer that in 3 to 4 sentences

Answer 5

To create a scale model of the solar system, choose an appropriate scale and select objects to represent the Sun and each planet. Position the Sun at the center and place the planet models at accurate distances from it. Ensure the sizes of the objects correspond to the scale chosen to accurately represent the sizes and distances of the celestial bodies.

Answer 6

in 3 to 4 sentences explain the evidence that supports the idea that water may have come onto earth by comets

Answer 7

The presence of deuterium, a heavier isotope of hydrogen, in the Earth's oceans supports the idea of comets bringing water to our planet. The ratio of deuterium to ordinary hydrogen found in comets matches that of Earth's oceans. Furthermore, studies of the comet 67P/Churyumov-Gerasimenko by the Rosetta spacecraft detected water vapor, ice, and organic molecules, reinforcing the theory that comets carry water. Finally, the isotopic composition of Earth's water, as compared to other bodies in the solar system, suggests a common origin with comets.
