Apencil sharpener has a handle with a radius of 1.5 cm. the sharpening mechanism has a radius of 0.5 cm. what is the ima of the pencil sharpener?
a-0.33
b-0.5
c-3
d-5

The correct answer is option C.

Explanation:

IMA (Ideal Mechanical advantage) is defined as ratio of input distance to the output distance.

Radius of the handle of the sharper = =1.5 m

Radius of the sharping mechanism = =0.5 m

3 is the IMA of the pencil sharpener. Hence, option C is correct.

answer: c.

explanation:

the atomic number will stay the same no matter how many electrons it has, so it doesn’t decrease nor increase. it’ll only change with a different number of protons
