Answer:
9.8m/s
Explanation:
acceleration due to gravity is independent of mass
The first law, which deals with changes in the internal energy, thus becomes 0 = Q - W, so Q = W.
If the system does work, the energy comes from heat flowing into the system from the reservoir; if work is done on the system, heat flows out of the system to the reservoir
<span>If 1 eighth equals 1 billion 7 eighth equals 7 billion.
The asker of the second question needs a tutorial in radiometric dating. There is little likelihood that the daughter isotope has the same atomic weight as the parent isotope. To measure the mass isotopes doesn't tell us how many atoms of each exist. To get around that let's pretend — which will likely serve the purpose ineptly intended — that the values give an the particle ratio, 125:875.
The original parent isotope count was 125 + 875 = 1000. The remaining parent isotope is 125/1000 or 1/8. 1/8 = (1/2)^h, where h is the number of half-lives.
h = log (1/8) ÷ log(1/2) = 3
And 3 half-lives • 150,000 years/half-life = 450,000 years.</span>
The force exerted on the cart 2 during the collision is 2 N.
The given parameters:
- <em>Mass of cart 1 = m1 = 1 kg</em>
- <em>Mass of cart 2 = m2 = 2kg</em>
- <em>Force applied on cart 1 = 2 N</em>
According to Newton's third law of motion, action and reaction are equal and opposite. The force exerted on cart 1 is equal in magnitude to the force exerted on cart 2 but in opposite direction.
Thus, the force exerted on the cart 2 during the collision is 2 N.

It will be option G because from gas to solid the kinetic energy decreases which makes the molecule more stable because of this the solid is stable. so yeah.
