The solution for this problem:
PV = nRT
But we are looking for n so, alter the original formula:
n = PV / RT
= (1.00 atm) x (2.09 x 10^8 L) / ((0.08205746 L atm/K mol) x (25.1 + 273.15 K))
= 8539801.26 mol H2
total volume = (8539801.26 mol H2) x (-286 kJ/mol H2) = -2.44 x 10^9 k J
Answer:
Heldi is right
Explanation:
It will not move even if more people or one person gets off it will stay the same til a force pushes down on it.
Holaaa, qué tal, cómo estás?
Otal energy= PEmax on the spring = KEmax of the oject
<span>Total Energy= KE+PE at v or x not maximum. </span>
<span>Using the second line </span>
<span>E= 3/4 E + PE </span>
<span>PE = 1/4 E </span>
<span>PEmax =E = 1/2 kA^2 </span>
<span>PE=E/4 = (1/2)kA^2 / 4= kA^2/8
</span>

Answer:
Acceleration of the bullet will be 1778835.6 
Explanation:
We have given length of the barrel refile s= 0.855 m
When the bullet leaves the muzzle its velocity is 553 m/sec
So final velocity v = 553 m/sec
Initial velocity will be 0 that is u = 0 m/sec
According to third equation of motion
