Answer: The mass M = 9g, so G = 9g x 9.8 m/s² = 88.2gm/s², or 88.2 newtons. Insert the tension and gravitational force you just calculated into the original equation: -F = T + G = 18N + 88.2N = 106.2N. The force is negative because the object in the pulley system is accelerating upwards.

Answer:
Explanation:
Molecular formula of penicillin = C₁₆ H₁₈ N₂ O₄S
No of hygrogen atoms = 36
No of molecules = 36 / 18 = 2
molecular weight = 334 amu
molecular weight of 2 molecules = 334 x 2 = 668 amu.
Answer:
The answer would be A
Explanation:
If more solvent is added, the solution becomes unsaturated because in principle it is capable of dissolving more solute.
