Answer:
Explanation: is that suppose to be the question or are you just saying?
Here's the formula for mechanical advantage.
It's very important, and you should memorize it:
Mechanical Advantage = (output force) divided by (input force) .
#1). Force that moves the object = output force = 550N
Force that it takes = input force = 200N
Use the formula:
(output force) divided by (input force) = 550N/200N = 2.75 .
#2).
#3).
#4).
#5).
#6).
#7).
#8).
#9).
#10).
All of the rest of the problems on the page tell you the input force
and the output force. They can be solved by using the same formula
to calculate the mechanical advantage, just like I did in #1).
I disagree with the first sentence of #11. But by the time you get there,
you'll be an expert in mechanical advantage, so you can investigate and
decide who's correct ... the sheet or me.
Answer:
7.8 N
Explanation:
Applying,
I = Ft................. Eqaution 1
Where I = Impulse on the egg test dummy, F = Force on the egg test dummy during the time interval, t = time interval
make F the subject of the equation
F = I/t.................. Equation 2
From the question,
Given: T = -0.39 N.s, t = 0.050 s
Substitute these vales into equation 2
F = -0.39/0.050
F = -7.8 N
Hence the force that act on the egg test dummy is 7.8 N
The answer is B. metalloids
(boron, silicon, germanium, arsenic, antimony, tellurium, astatine, and polonium)
Answer:
Th e correct answer is B. Balance
Explanation:
Balance is an ability of a body to maintain the line of gravity with negligible postural sway. Sway is the horizontal movement of the center of gravity of a body if a body is standing still.
If you want to stay for a long period of time in one position without movement, then you need balance. So the term refers to the use of strength to hold the body's position is balance.
Agility refers to the flexibility of the body or jumping
Power means Strength in general
Speed is the ability that how can a person run fast.
