The planet Krypton has a mass of 8.4 x 1023 kg andradius of 3.4 x 106 m.
What is the acceleration of an object in free fall near thesurface of Krypton? the gravitational constant is 6.6726 x10-11 N x m2 /kg2 . Ans. in unitsof m/s2 .

The acceleration of the object is 4.847m/s^2

Explanation:

Acceleration due to gravity g is given by:

g =(G×M)/R^2

Where G is gravitational constant

M is mass of object

R is radius

g =(6.6726×10^-11)×(8.4×10^23) /(3.4×10^6)^2

g=5.605×10^13/1.156×10^13

g= 4.847m/s^2

i guess that visual aids present persuasive examples to what you are presenting, some factors would be theme (does it fit with the color, information, what you are presenting), size (can you see it, is it a big enough span of data/information), and overall look of the visual aid.

hope this : )
