لو سمحتوا أريد شرح هذه الاسئلة وطريقة حلها باللغة العربية
PHY 011
1. Suppose we measure the force of different masses that acts on the object moving on horizontal axis regard to the following relation:
F= a M
Where
M is mass in kg, F is the Force in Newton, and a is the acceleration
The data which we got is represented in the below table:
M (Kg) F(Newton)
0.25 2
0.5 3.5
0.75 5
1.5 6.2
Use the pervious data for:
a. Plot the graph that represents the relation
b. Calculate the slope
c. What quantity represented by the slope?
d. Calculate the y-intercept of the graph?
e. writes the unit of the slope
2. Suppose we measure the density of steel ball and it was 6.34 g/cm3 where the true value of the density of steel is 7.89 g/cm3, calculate the percentage error of the density?
