Answer : When the forces are acting in the same direction of movement of the object it can be said as sum of the two individual forces will be equal to the "NET FORCE" .
Example : If two forces (2 kids pushing in the same direction to move the object big box) act on an object(big box) in the same direction, then the net force is equal to the sum of the two forces.
Osmotic pressure is mathematically expressed as
π = CRT
where, C = concentration of solution
R = gas constant = 0.082 atm mol-1 K-1
T = temperature = 300 K
π = osmotic pressure = 0.55 atm
∴ 0.55 = C X 8.314 X 300
∴C = 0.022 M
Now, conc of solution (in terms of molarity) =
Given: weight of solute = 0.9 g
volume of solution = 100 ml = 0.1 l
∴ 0.022 =
∴ Molecular weight = 4.09 g/mol
Greater absolute charge
- This is because ionic bond results from stronger electrostatic forces of attraction.
- The higher the value of charges q₁ and q₂ the stronger will be the ionic bond.
Its a nuclear weapon explosion device that derives its destructive force from nuclear reactions, either fission or a combination of fission and fusion.
