1 The Earth's Moon has considerably less mass than the Earth itself. Not only is the Moon smaller than the Earth but it is only about 60 percent as dense as Earth. Thus the gravitational attraction on the Moon is much less than it is here on Earth and a person weighs less on the Moon
2 The strength of the gravitational force between two objects depends on two factors mass and distance. the force of gravity the masses exert on each other. If one of the masses is doubled the force of gravity between the objects is doubled increases, the force of gravity decreases.
3 If the mass of one of the objects is doubled, then the force of gravity between them is doubled. If the separation distance between any two objects is tripled (increased by a factor of 3), then the force of gravitational attraction is decreased by a factor of 9 (3 raised to the second power).
4 idk about this one
Carbon dioxide and oxygen
Answer:
During photosynthesis, oxygen and hydrogen ions are formed from the splitting of water. To replace the electron, a molecule of water is split. This splitting releases the electron and results in the forming o oxygen and hydrogen ions. The hydrogen ions then get pumped into the inner thykaloid space and can be used to make ATP.
Explanation:
Hope this helps!
Answer:
B. the variable that is changed and being tested
Answer:
The first step in the Scientific Method is to make objective observations. These observations are based on specific events that have already happened and can be verified by others as true or false. Step 2. Form a hypothesis.
