The acceleration of gravity is inversely proportional to
the square of the distance from Earth's center.
The acceleration of gravity is 9.8 m/s² on the Earth's surface ...
6380 km from the center.
If the acceleration of gravity at 'h' is 4.9 m/s² ... 1/2 of what it is
on the surface, then the distance from the center is
(6380 x √2) = 9,023 km (rounded) ,
and 'h' is the distance above the surface
= (9,023 - 6,380) = 2,643 km (rounded) .
Answer:
What inferences can you make about the melting points of the different substances and the motion of their particles, based on the data? (ignore that needed it here so i could see it better.)
Explanation:
Butter has a lower melting point than the cheese and the wax. The motion of the cheese were a little separated while the butter articles have more space in between. The wax had the closest particles.
I dont know if that makes sense?
Nope, color change can also occur during a physical change.
The lemon trees will always be the same so they are the constants. The independent variable is the water amount because it is changing. The dependent variable is the amount of lemons because it is the variable being tested. (If we change the amount of water how many lemons will be produced?)
<h3>
Answer:</h3>
35 meters
<h3>
Explanation:</h3>
<u>Data given;</u>
- Velocity of an object = 5 m/s
- Time taken = 7 s
We are required to calculate how far the object traveled.
Velocity = Displacement ÷ time
Displacement = Velocity × time
= 5 m/s × 7 s
= 35 m
Therefore; the object traveled 35 meters
