Multiple organisms fight for the same recourses
Answer:
5000 J
Explanation:
Given that,
Weight of Danny Diver, F = 500 N
He steps off a diving board 10 m above the water
We need to find the kinetic energy of the water with which it hits. Let its is K. It is given by :
E = mgh
Where g is acceleration due to gravity
So, he hits the water with kinetic energy of 5000 J.
Answer:
khoảng cách = 8km / h
Explanation:
khoảng cách = tốc độ / thời gian
khoảng cách = 12/40
khoảng cách = 8km / h
I believe it'd accelerate at 1.25 m/s^2 instead of 1, as it lost 1/4 of its mass (.25), so now it is .25 of 1 faster.
The air that was inside the balloon will expand to fill the room
Explanation:
Matter exists in three states:
- Solid: in a solid, the molecules are bound to each other by strong intermolecular bonds, so they are not able to move freely, but only to vibrate around their fixed position. As a result, solids have a definite shape and a definite volume.
- Liquid: in a liquid, the molecules are free to slide past each other, however there are still intermolecular forces acting between them that prevent them to move too far apart from each other. As a result, liquids have a definite volume, but not a definite shape.
- Gas: in a gas, intermolecular forces between molecules are negligible, and molecules can move freely. As a result, gases have no definite volume and no definite shape.
According to the definition of gas, this means that in this problem, when the air is released from the balloon, the molecules of air will move out of it and will try to fill the whole space available, which is the room.
