Answer:
18 L
Explanation:
Use ideal gas law:
PV = nRT
Find initial number of moles, but first convert to units that match the gas constant units.
(200,000 Pa) (0.025 m³) = n (8.314 Pa m³ / mol / K) (25 + 273.15 K)
n = 2.017 mol
At the new pressure and temperature:
(250,000 Pa) V = (2.017 mol) (8.314 Pa m³ / mol / K) (0 + 273.15 K)
V = 0.018 m³
V = 18 L
Solid, liquid, gas and something else
Applying Newton's Second Law of Motion, the acceleration of the ball is 16.8
<u>Given the following data:</u>
- Acceleration due to gravity = 9.8
To find ball's acceleration, we would apply Newton's Second Law of Motion:
First of all, we would determine the net force acting on the ball.
×
Downward force = 4.9 N
Net force = 8.4 N
Mathematically, Newton's Second Law of Motion is given by this formula;
<em>Acceleration = 16.8 </em><em />
Therefore, the acceleration of the ball is 16.8

Answer:
A) F = -9.8 N
, B) F = 18.62 N
Explanation:
The Archimedes principle states that the thrust force is equal to the liquid farts dislodged by the body.
Let's apply Newton's equations
F = B –W
Thrust force is
B = ρ_water g V
Let's reduce volumes to the SI system
V = 14.3 L (1 m³ / 1000 L) = 14.3 10⁻³ m³
A) Tank full of air
m = 12.4 +2.9 = 15.3 kg
F = ρ_water g V - mg
F = 1 10³ 9.8 14.3 10⁻³ - 15.3 9.8
F = 140.14 -149.94
F = -9.8 N
The negative sign indicates that the force is descending
B) Empty tank
m = 12.4 kg
F = 1 103 9.8 14.3 10⁻³ - 12.4 9.8
F = 140.14 - 121.52
F = 18.62 N
Force is up
The answer is D, only B is a mineral. I always look at it as mineral's atoms are usually closer together but always check your answers.
