D) increases the input distance

Answers

C) changes the direction of the input force

Explanation:

A weight machine measure the normal reaction of a body place on the machine.This means the force will have no acceleration. The body placed on the machine will thus exert the force due to gravity and the normal reaction will  act  in the opposite direction to it.

What is polygamy? Explain please:)

Answers


I always thought that 'polygamy' refers to the social system in which a man
may have more than one wife, and I thought there's some other word for
where a woman is married to more than one man. 

But when I went to look it up just now to answer your question, (which by the
way you could also have done very easily), I found a definition that says it's a
"state of marriage between many spouses".  That doesn't specify genders, so
I guess it means any marriage that involves more than two people, no matter
how the genders may be represented or distributed within it.

Polygamy is the marriage that includes two or more partners, like a husband with four wives.
