Mechanical advantage = ideal mechanical advantage x efficiency = 3.5 x 0.6 = 2.1
The mechanical advantage of the inclined plane is 2.1
Answer:
The value of spring constant is 266.01 
Explanation:
Given:
Mass of pellet 
kg
Height difference of pellet rise 
m
Spring compression 
m
From energy conservation law,
Spring potential energy is stored into potential energy,
Where 
spring constant, 
Therefore, the value of spring constant is 266.01
Answer:A air
Explanation:Of the three mediums (gas, liquid, and solid) sound waves travel the slowest through gases, faster through liquids, and fastest through solids. Temperature also affects the speed of sound.
