Answer:
D. The input force is equal to the output force
Step-by-step explanation:
A pulley changes the direction of the applied force, but does not change its magnitude. The mechanical advantage is the ratio of output force to input force, so must be 1 when the force magnitude does not change.
Answer:
To represent parts of whole numbers, we use fractions.
So if 4 kids are sharing 3 cookies, what happens?
First, we divide one cookie into four equal parts, and give one part to each kid. Then we do the same with the second cookie, and then with the third one.
In the end, each kid will have three pieces. Each piece is a whole cookie divided into four equal parts.
So we represent this amount as
3 (Number of parts) & 4 (How many equal parts the whole is divided into)
3
4
as a fraction
A fraction is made of two numbers :
67 because 24 isnot 50 yet so you would keep 67 how it is but if it was 50 or more then you would round it up to 68
