According to the Free Body Diagram of pulley system:
MA = W/T = n.
Here, MA is the mechanical advantage, W is the load, T is the tension, and n is the number of sections of rope supporting the load.
Let's calculate the ratio: 1700/340 = 5
Which means the T = 1/5 W, it can be achieved by compound pulley system with 4 or 5 pulleys.
So MA = 5, this is your answer.
A atom can become an ion with a -2 charge, if it gains 2 electrons during a chemical reaction.
Answer:
529.15 m/s
Explanation:
h = Maximum height = 70000 m
g = Acceleration due to gravity = 2 m/s²
m = Mass of sulfur
As the potential and kinetic energies are conserved
The speed with which the liquid sulfur left the volcano is 529.15 m/s
Yes. a physical change is only modifying the structure of it.
a chemical change is permanently changing something.
cutting cheese into slices is a physical change
cooking an egg is a chemical change
