Which of the following are true concerning Newton's Law Of Gravitation?

The graviational force is related to the mass of each object
The graviational force is an attractive force
A large and a small object are gravitationally attracted to each other. The magnitude of the gravitational force on the larger object is greater than on the smaller
The gravitationsal force on a satellite is greater at an altitude of 1000km above the earth than at an altitude of 500km
The gravitational force between the earth and a person is constant, no matter how high the person is above the surface of the earth

Explanation:

I think these are the answers

1) True: The gravitational force between two objects depend on their masses and distance.

2) True: The gravitational force between objects is always attractive, meaning the force vectors will always point towards each other. (think Newton's 3rd law)

3)True: There will always be some sort of gravitional attraction between objects although it would be close to 0 for small objects.

4)False: the force applied on each object are equal (remember: Newton's 3rd law).

5)False: The further the satellite is from the surface of a planet, the weaker the gravitional force is between them. The force is a max at the surface of the planet.

6)False:(same as 5's explaination)

to be honest as much as i would love to answer this. i feel as if something's missing. just saying.

  1.the balanced   chemical equation is as below

cu +   2 ag(no)₃ → cu(no₃)₂   +2 ag

2.the   much silver   produced   is   50.9 g

step 1: find the   moles of cu

moles =   mass÷   molar mass

  from periodic table the molar mass of cu = 63.5 g/mol

moles is therefore = 15.00 g÷ 63.5 g/mol = 0.236   moles

step 2: use the mole ratio to determine the   moles of ag

from equation above   cu: ag   is 1: 2

therefore the moles of ag   =0.236   moles   x 2/1 =0.472   moles

step 3: find the mass   of ag

mass = moles x molar mass

from periodic table   the molar mass of ag =107.87 g/mol

mass   = 0.472   moles x 107.87 g/mol = 50.9 g

3.   the   much   silver   collected worth is   1.797 oz

  convert   50.9 g   to oz

that is   1 gram = 0.0353 oz

          50.9 grams =?   oz

by cross multiplication

={(50.9 grams x 0.0353 oz) / 1   gram}   =1.797 oz
