(a) what is the acceleration of gravity on the surface of the moon? the mass of the moon is 7.35 x 1022 kg and its radius is 1.74 x 106 m. (b) what is the acceleration of gravity on the surface (or outer limit) of mercury? the mass of mercury is 3.30 x 1023 kg and its radius is 2.44 x 106 m

Part a)

a = 1.62 m/s/s

Part b)

a = 3.70 m/s/s

Explanation:

Part A)

Acceleration due to gravity on the surface of moon is given as

here we know that

now we have

Part B)

Acceleration due to gravity on surface of Mercury is given as

here we know that

now we have

come closer and become far apart and become steam/gas

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
