Determine the acceleration due to gravity on the surface of planet x.

Answer : The acceleration due to gravity on the surface of planet X is,

Explanation :

Force : It is defined as the product of the mass of an object and the acceleration due to gravity.

Formula used :

where,

F = force

m = mass of an object

a = acceleration due to gravity

Now we have to calculate the acceleration due to gravity from the graph.

   (from the graph)

Putting all the values in this formula, we get the acceleration due to gravity.

Therefore, the acceleration due to gravity on the surface of planet X is,

the old price per ounce is c/4.

the new price per ounce is c/3.6.

the ratio of the old price to the new one is

(c/4)/(c/3.6) = (c/c)×(3.6/4) = 0.9 . . = 9/10 . . "nine tenths" in either form
