Answer: option container C: the purple dots.
Explanation:
There are four physical states of matter:
1) Gas: in this state the neutral atoms or molecules are separated, moving freely, so that the particles occupy the whole container. The best representation corresponds to the paired green/orange dots in cylinder B: the dots are paired, meaning that they are not free ions, but neutral particles, and they occupy the entire sapece inside the cylinder.
2) Liquid: in this state the molecules are closer than in the solid stated. They yet flow (the molecules or atoms slip respect the others and can pass to each other). There is some attraction between the molecules so they cannot occupy the entire space in the container, but they can adopt the shape of the part where they are. This is perfectrly represented by the purple dots in the cylinder C.
3) Solid: the molecules or ions are tighty packed. They cannot pass each other. They are in fixed position. They vibrate in fixed positions. The substance do not change the form to adapt the container. This is represented by the red dots in cylinder D.
4) Plasma: is a state similar to gas, but the particles are free ions. That is what the blue dots in cylnder A.
The acceleration of gravity is 9.8 m/s² . That means that a falling object
is always falling 9.8 m/s faster than it was falling 1 second earlier.
If an object is not slowed by air resistance, and has far enough to go
so that it's still falling after three whole seconds, then at the end of
three seconds it's falling at
(9.8 m/s²) x (3 sec) = 29.4 m/s
Answer:
Part a)
Part b)
It will not able to cross the pole
Explanation:
As we know that ball is hit with speed of 110 ft/s at an angle of 35 degree
so here we will say
now at the maximum height the vertical velocity will become zero
so here we can use kinematics
here we have
now we have
Part b)
now the height of ball is related to the distance from point of projection is given as
now we know that
since its coming negative so it will not able to cross the pole
C) In the absence of an unbalanced force, an object at rest will stay at rest and an object in motion will stay in motion.
hope this helps and have a great day :)
