Answer: MA = 5
Explanation:
The mechanical advantage is the ratio of the load to the effort. It is a measure of how efficient a simple machine is.
MA = Load/Effort
Load = 35N
Effort = 7N
Therefore
MA = 35N/7N
MA = 5
Since the mechanical advantage is more than 1, the lever is highly efficient as it allows a very small effort to overcome 5 times its magnitude of load.

Hello User,
Volcanic fragment thrown into air during volcanic eruption is called tephra. Tephra rocks are classified by size.
Answer:
7.54 m/s
Explanation:
C = 2πr
C = 2π (0.450 m)
C = 2.827 m
v = d / t
v = 25.0 (2.827 m) / (9.37 s)
v = 7.54 m/s
