A low-frills patio or deck is pretty cheap. Everyone's definition of cheap is different, but decks can be had for as low as $1,000, according to Jessica Piha, a spokeswoman for Porch.com, a website that helps homeowners find the right contractor. But the average deck costs $8,300, Piha says. And how much is a cheap patio? The cost to install a 200-square-foot concrete patio is about $740 to $840 on average, according to HomeWyse.com, an online reference for home projects. But here's why you probably won't buy a cheap patio. If you're pining over someone's patio, you presumably don't want a concrete slab.
The acceleration due to gravity on the surface of the Moon. The mass of the Moon is 7.35 x 10^22 kg and the average radius of the Moon is 1.74 x 10^6 m. Plugging into the formula, we have: g = (6.67 x 10^-11 N-m^2/kg^2)(7.35 x 10^22 kg )/(1.74 x 10^6 m)^2 = (4.9 x 10^12 )/(3.03 x 10^12) = 1.6 m/s^2.
The force of Gravity is  determined by the mass and distance between two or more objects.  The other force that keeps the moon in o â¦ rbit is the moon's inertia.  Without inertia the moon would simply fall into Earth; because of  Gravity, the same would happen with the planets and the sun.Answered.hat's the mutual force of gravitation (gravity) between the Earth and the Moon. This, combined with the Moon's velocity (its inertia), results in the orbital path that the â¦ Moon follows. 50 people found this useful. Al Cohen.
