Answer:
The correct false statement is;
As the stone rises, its potential energy decreases
Explanation:
When the stone is thrown straight up into the air, the initial velocity, u, progressively decreases according to the following equation;
v = u - g·t
Where;
v = The final velocity
g = The acceleration due to gravity = 9.81 m/s²
t = The time taken
Therefore whereby, the kinetic energy. K.E. is given by the equation , K.E. = 1/2 × m × u², as u reduces, the kinetic energy reduces
However, the potential energy, P.E. is given as P.E. = m × g × h
Where;
h = Height
m = The mass of the stone
Therefore, as the stone rises, the potential energy increases.
Answer:
change of speed or direction
This is chem....This is a Boyle's law question
PiVi = PfVf
Rearrange to solve for unknown Pf
Pf = PiVi / Vf
= 310 x 185 / 74
= 775 mm Hg
You can convert the pressure to kPa if you needed to
