A model shows that the moon has grown to twice its size, yet it has remained in the same place. In one to two sentences, explain how this would impact the gravity between Earth and the moon.
?
If the moon has grown in size, the gravity between Earth and the moon would become stronger due to the increase in mass.
A student wants to draw a scale model of the solar system. In three to four sentences or bullet points, explain what steps should be taken to create this model.(4 points)
1. Determine a suitable scale: Decide on a scale that will allow the student to represent the large distances between the planets accurately. For example, 1 centimeter might represent 1 million kilometers.
2. Research the dimensions and distances: Look up the size of each planet (in terms of diameter) and its average distance from the sun. Use this information to calculate the scaled-down measurements for the model.
3. Create representations of the planets: Use materials like foam balls or clay to represent each planet in the solar system. Ensure that the size of each planet is accurately scaled down based on the chosen scale.
4. Arrange the planets according to their scaled-down distances: Place the representations of the planets in the model according to their scaled-down distances from the sun. Make sure to leave enough space between the planets to accurately represent the vast distances in space.
