There is no "why", because that's not what happens. The truth is
exactly the opposite.
Whatever the weight of a solid object is in air, that weight will appear
to be LESS when the object is immersed in water.
The object is lifted by a force equal to the weight of the fluid it displaces.
It displaces the same amount of air or water, and any amount of water
weighs more than the same amount of air. So the force that lifts the
object in water is greater than the force that lifts it in air, and the object
appears to weigh less in the water.
Answer:
Explanation:
Given:
mass of first particle, 
mass of second particle, 
mass of third particle, 
coordinate position of first particle in meters, 
coordinate position of second particle in meters, 
coordinate position of third particle in meters, 
<u>Now, gravitational force on particle 3 due to particle 1:</u>
towards positive Y axis.
<u>gravitational force on particle 3 due to particle 2:</u>
towards positive X axis.
<u>Now the net force</u>
<em>For angle in counterclockwise direction from the +x-axis</em>
Answer:
The student is getting different info bc the students probable keeping track of the distance instead of the displacement.

Explanation:
Thats what I would go with but I didn't read the article so I don't know what context was used. Good luck! :)
Well we know it has to be greater than 300,000 km/s since we can't see it.
We can't calculate it any closer than that using the given information.
