You use a wedge that has a width of 2.8 cm and a slope length of 5.1 cm. what is the mechanical advantage of this wedge?

1.82

Explanation:

The mechanical advantage of a simple machine is the ratio between the output force (load) and the input force (effort).

For a perfect wedge (efficiency of 100%), the mechanical advantage is also given by:

where:

L is the length of the slope

w is the width of the wedge

For the wedge in this problem, we have:

L = 5.1 cm is the slope length

w = 2.8 cm is the width

Therefore, the mechanical advantage is:

multiple allele inheritance is traits controlled by more than 2 alleles (ex: pigeons having 3 alleles of one gene govern their feather color).

so easy. just google the electromagnetic waves and it’ll pop up.
