A bowling ball (mass = 7.2 kg, radius = 0.10 m) and a billiard
evablogger [386]

Answer:

Maximum gravitational Force: F_{gmax} = 1,026*10^{-08} N

Explanation:

The maximum gravitational force is achieved when the center of gravity are the closer they can be. For the spheres the center of gravity is at the center of it, so the closer this two centers of gravity can be is:

bowling ball radius + billiard ball radius = 0,128 m

The general equation for the magnitude of gravitational force is:

F_{gmax}  = G \frac{M*m}{r_{min}^{2} }

Solving for:

G = 6,67*10^{-11}  \frac{Nm^{2}}{kg^{2}}

M = 7,2 kg

m = 0,35 kg

r_{min} = 0,128 m

The result is:

F_{gmax} = 1,026*10^{-08} N

By using the following reactions, calculate the heat of combustion of pentane:
Sergio [31]
To answer this problem, we use Hess' Law to calculate the overall enthalpy of the reactions. The goal is to add all the reactions such that the final reaction is C<span>5H12 (g) + 8O2 (g) → 5CO2 (g) + 6H2O (l) through cancellation adn multiplication. The first equation is multiplied by 5, the second one is multiplied by 6 and the third one is reversed. The final answer is -3538 J or -3.54 x10^3 kJ.</span>
