The formula for the force of gravity has ( M₁ · M₂ / D² ) in it.
After the changes, the new force will have ( 0.5M₁ · 0.5M₂ / (0.5D)² ) .
We can separate the new numbers from the original force, like this:
( 0.5M₁ · 0.5M₂ / (0.5D)² )
= ( 0.5 · 0.5 / (0.5)² ) times ( M₁ · M₂ / D² )
The first factor boils down to ' 1 '. So, those changes would
leave the strength of the force unchanged.
That's what I think.
Answer: I believe it is, "New evidence was discovered that made scientists revise their ideas"
Explanation: I don't think that people can travel under the plates :D
Answer:
B. 17m/s
Explanation:
This question contains a graph that illustrates the relationship between the speed of a car over time. The graph shows that one can make an inference of the amount of time it takes for the car to cover a particular speed and vice versa.
In this case, after 3 seconds, the speed of the car will be 17 m/s. This inference was got by tracing the position of 3s in the x-axis to the value on the y-axis. Doing this, the best inference for the speed of the car after 3 seconds is 17m/s.
Answer:
Hydrogen bond.
Explanation:
It is an intermolecular bonding interaction between two molecules of different electronegative values or bonding between lone pairs of electron rich molecules.
Hydrogen-bonding forms in liquid water as the hydrogen atoms of one water molecule are then attracted towards the oxygen atom of a neighboring water molecule resulting in a general proton shared by two lone electron pairs.
