A non-sandblasted rock could be rough or smooth depending on how it was formed.
A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
Its pretty easy, correct answer is D
Actually, Henry's Law is an empirical value. It means that it was not obtained out of raw calculations or correlations. This was gathered from experimental results. Hence, you can search its data. At standard temperature of 25°C (298 K),
k = k°e^[2400(1/T - 1/T°)], where k° = 29.4 L·atm/mol
Substituting the values so that T would be in 20°C or 293 K,
k = (29.4 L·atm/mol)e^[2400(1/293 - 1/298)]
k = 33.7 L·atm/mol
1/4 Ao = Ao * ( 1/2)^(t/106)
t = 212

Answer : 10 plague hearts are there in one map at a time in state of decay 2
Explanation : The State of Decay 2 consists of 10 Plague Hearts which one needs to destroy and they are placed on randomly dotted areas around the map inside a searchable location on it.
With each heart that one destroys, the remaining other ones become a little bit tougher and are more heavily guarded by the undead people.
