The work done=700 joules
The mechanical advantage=8
Explanation
1.The force with which the player throws the ball F=20 newtons
The distance traveled by the ball D=35 m
we have to calculate the work done by the ball
W=F*D
=20*35=700 N/m=700 joules
2. the input force exerted on the lever =25 N
output force of the lever=200 N
we have to calculate the mechanical advantage which is the ratio of output force to input force
MA=output /input
=200/25=8
Answer:
2.5 shirts (perhaps 2 since you can't "make" half a shirt)
Step-by-step explanation:
450 bolts → 1125 shirts
1 bolt → 1125/450 shirts = 2.5 shirts
Can you post what it says? I could probably help you out.
A. homeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant.
Multiply it just like you are multiplying two numbers with two digits. The at the end of your answer make place the decimal so that there are still numbers in the hundredth place.
