Answer:
30kg m/s.
Explanation:
30 kg m/s
Explanation
Momentum = Mass × Velocity = 10 kg × 3 m/s = 30 kg m/s
Its momentum is 30 kg m/s.
Explanation:
Momentum is defined by the following equation:
p=mv
where m is the mass of the object in kilograms, v is the velocity of the object in meters per second
p=10 kg⋅3 m/s
=30 kg m/s

In order to answer this, you need to find the empirical data for the standard entropies. Please refer to this link: http://www.mrbigler.com/misc/energy-of-formation.PDF
For NO₂ gas, the entropy is 240 J/mol-K. For N₂O₄ gas, the entropy is 304.2 J/mol-K. Therefore, <em>the statement is false.</em>
Answer:
69.7231 u to 4 decimal places.
Explanation:
Gallium is composed of two natural occuring isotopes that is Ga-69(60.108%) with mass of 68.9256 amu and Ga-71(39.892%) with mas of 70.9247 amu. The ratio of their masses are 1.0290. The relative abundance of Ga-69 is 60.11% and Ga-71 is 39.89%.
Calculate average atomic mass of Ga-69 :
Ga-69 = 60.108% = 0.60108.
GA-71 = 39.892% = 0.39892.
Atomic mass of Ga = (68.9256⋅0.60108)+(70.9247⋅0.39892)
AM(Ga)=69.7231 u to 4 decimal places.
