The IMA of the lever is 10
Explanation:
The IMA (Ideal Mechanical Advantage) of a simple machine is given by:
[tex]IMA=\frac{d_e}{d_r}[/tex]
where
[tex]d_r[/tex] is the length of the resistance arm
[tex]d_e[/tex] is the length of the effort arm
For the lever in this problem, we have:
[tex]d_r = 7 cm = 0.07 m[/tex] is the length of the resistance arm
[tex]d_e = 0.7 m[/tex] is the length of the effort arm
Substituting into the equation, we find the IMA of the lever:
[tex]IMA=\frac{0.7}{0.07}=10[/tex]
