Answer:
734.215N
Explanation:
First we calculate the angle that corresponds to a 5% slope using the Tan-1 function
then we use the component that corresponds to the direction parallel to the road, additionally we must multiply by the gravity value to find the weight(g=9.81m/s^2)
Wx=M*g*sen(2.86)=1500kg*9.81*sen(2.86)=734.215N
Complete Question
The complete question is shown on the first uploaded image
Compare the percent error between your value and the accepted value of 1.26 times 10-6 T · m/A. (Use the accepted value given to three significant figures in your calculation.). 100% % error = %
Answer:
The permeability of free space is
The percentage error is % error = 5.25%
Explanation:
From the question we are told that
The slope is , and
Generally
So
From the relation given in the question
Where R is the radius of the coil
N is the number of loops of the coil = 10
Now from the question we are told that
substituting into the equation above
Substituting values
Generally the % error is mathematically represented as
%
Given that the accepted value is
Hence substituting values
%
