A lever has an input arm 50 centimeters long and an output arm 40 centimeters long. What is the mechanical advantage of the lever? (MA=Input distance / Output distance) a 2.0 b 1.25 c 1 d 0.8
Answer:
45
Explanation:
well 45
Mechanical advantage will be option b)1.25
What is Mechanical advantage ?
Mechanical advantage equal to the ratio of length of the input arm and output arm
Given
Input arm = 50 cm
output arm = 40 cm
Mechanical advantage = Input distance / Output distance
= 50 / 40
= 1.25
Mechanical advantage will be option b)1.25

Rahul sees a flock of birds. He watches as the flying birds land in neat little rows on several power lines. Which change of state does the motion of the birds most closely model?
melting
vaporization
deposition
sublimation
Answer:
C.) Deposition.
Explanation:
I just took the unit test
The change of state that Rahul sees and models the motion (movement) of the birds is called deposition.
What is deposition?In physics, deposition can be defined as a transition phase from a gaseous state to a solid without the need to pass to a liquid state.
The physical phenomena of deposition are relatively common in nature and they include many natural processes.In conclusion, the change of state that Rahul sees and models the motion (movement) of the birds is called deposition.
