Mass of a model car you measured = 230 grams
Actual mass = 218 grams
Percent error = ?
First subtract the actual value from the value
you measured,
230 grams – 218 grams = 12 grams
Now divide 12 grams by the actual mass that is
218 grams:
12 / 218 = 0.055
Now multiply 0.055 with 100 to get the percent
error;
0.055 x 100 = 5.5%
So, the Percent error is 5.5%.
<h2>
Mass of object in Earth is 1.37 kg</h2>
Explanation:
On planet B where the magnitude of the free-fall acceleration is 1.91g , the object weighs 25.74 N.
We have
Weight = Mass x Acceleration due to gravity
On planet B
25.74 = Mass x 1.91 g
25.74 = Mass x 1.91 x 9.81
Mass = 1.37 kg
Mass is constant for an object. It will not change with location.
Mass of object in Earth = Mass of object in Planet B
Mass of object in Earth = 1.37 kg
