1) the mass of an object gives gravity, the more massive an object is the more gravity it has on the things around it
2)the earth's mass is so much greater than our own that we feel it's gravity stronger than say the moon which has a smaller mass than the earth
3) mass and how far away you are from the object
4)as mass increases so does gravity (sorry I do not remeber the equation but there are some specific ones for different situations between two massive objects)
5) when distance increases, gravity decreases (again I do not remeber by how much)
M₁ x V₁ = M₂ x V₂
2.5 x V₁ = 0.50 x 100.0
2.5 x V₁= 50
V₁ = 50 / 2.5
V₁= 20 mL
hope this helps!
Thank you so much for the free points;)
Answer:
mitochondria is responsible for energy
Answer:
Explanation:
a) When the iron rod is heated, it expands (gets larger). That's the key to this whole procedure. It doesn't expand much -- depending on what temperature the iron rod is heated up to.
When the rod looks like it has expanded as much as it can, the rod is tightened as much as it can be tightened before damage is done. When the rod cools, it contracts (gets smaller). That brings the walls closer together or it stops the walls from bulging.
Very interesting question. I've never seen this. Thanks for asking.
