The ball's potential energy will decrease, and its kinetic energy will increase.
Explanation:
The ball's potential energy will decrease down the slope and its kinetic energy will increase.
Kinetic energy is the energy due to the motion of a body.
K. E = 
m v²
m is the mass of the ball
v is the velocity of the ball.
Potential energy is the energy due to the motion of a body down slope.
It is expressed as:
P.E = mgh
m is the mass of ball
g is the acceleration due to gravity of the body
h is the height.
We can see as the body drops down the slope, the height diminishes and the velocity increases.

Answer:
0.1593 L.
Explanation:
- We can use the general law of ideal gas: PV = nRT.
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and P are constant, and have two different values of V and T:
<em>P₁V₁T₂ = P₂V₂T₁</em>
<em></em>
P₁ = 600 torr/760 = 0.789 atm, V₁ = 185.0 mL = 0.185 L, T₁ = 25.0°C + 273 = 298.0 K.
P₂ (at STP) = 1.0 atm, V₂ = ??? L, T₂ (at STP = 0.0°C) = 0.0°C + 273 = 273.0 K.
<em>∴ V₂ = P₁V₁T₂/P₂T₁</em> = (0.789 atm)(0.185 mL)(298.0 K)/(1.0 atm)(273.0 K) = <em>0.1593 L.</em>
It’s ph level on the ph scale. 1-3 is a strong acid, 4-6 is a weak acid, 7 is neutral, 8-10 is a weak base, and 10-14 is a strong base.
the degree or intensity of heat present in a substance or object, especially as expressed according to a comparative scale and shown by a thermometer or perceived by touch. So I would have to go with A.
