Molarity and molality both describe the concentration of a substance in terms of moles.
Molarity describes the number of moles of a substance per unit of volume, typically per liter (mol/l).
Molality describes the number of moles per unit of mass, typically kilograms (mol/kg).
When determining the molality of a solution, mol/kg can be obtained by finding the number of moles in the substance, and dividing that number by the the total weight in kilograms of that substance.
When determining the molarity of a solution, mol/l can be obtained by dividing the number of moles in a substance by the total volume in liters of that substance.
The answer would be m1 = m2
FBD of m1 is the sum of the forces in the y direction =
0
0 = T - m1*g
transposing:
m1*g = T
FBD of m2 is the sum of the forces in the y direction = 0
0 = T - m2*g
transposing:
m2*g = T
set them equal to each other and solve for m1
m1*g = m2*g
= m1 = m2
Explanation:
The force on individual mass would be downwards or descending
and equal to the tension shaped by the other mass, which would be upward or
rising by the act of the seamless pulley, so the forces cancel on each mass.
The initial velocity of the potato is 54.41 m/s.
The given parameters:
- <em>Mass of the potato, m = 0.34 kg</em>
- <em>Mass of the cart, m = 5.0 kg </em>
- <em>Velocity of the recoil, u₂ = 3.7 m/s</em>
<em />
The initial velocity of the potato is calculated by applying the principle of conservation of energy as follows;
Thus, the initial velocity of the potato is 54.41 m/s.
