1. A 2300kg truck and a 1600 kg van each are .032 m apart. What is the force of gravity exerted on the truck ? 2.An elephant with a mass 895 kg is 18 m from a 255 kg zebra. What is the force of gravity on the elephant?
3.A hippo with the mass of 8000 kg was walking. He looked at some birds and decides to stand 1.5 m from a building with a mass of 1,500 kg. What was the force of gravity experienced by the hippo?
4.A grizzly bear that has a mass of 1,400 kg sits at one end of the park. At another location 130,000 m away, sits a giraffe with a mass of 5,800 kg. What is the force of gravity on the grizzly bear?
5. A 852 kg piano is sitting 14,000 m away from a 485 kg sound system. What is force of gravity on the piano?

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

8 m/s because for him to get the same amount of energy as ray is putting out, bobby, who weighs half as much as ray, needs to run twice as fast.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
