Answer
ω2=82.1 rpm
Explanation:
given required
m1=2.3 kg ω2=?
m2+m3=0.5kg
r1=10 cm
ω1=100 rpm
solution
Using the application of conservation of angular momentum we can solve as follows/
L before collision= L after collision
m1r²ω1=(m1+m2+m3)r²ω2
2.3 kg×0.1² m²×100 rpm=(2.3 kg+0.5 kg)×0.1²m²×ω2
2.3 rpm=0.028×ω2
ω2=82.1 rpm
Answer:
Explanation:
Given:
cross sectional area of the bone, 
factor of up-scaling the dimensions, 
Since we need to find the upscaled area having two degrees of the dimension therefore the scaling factor gets squared for the area being it in 2-dimensions.
The scaled up area is:
![a_s=[4.8 \times 10^{-4}]\times 10^2](https://tex.z-dn.net/?f=a_s%3D%5B4.8%20%5Ctimes%2010%5E%7B-4%7D%5D%5Ctimes%2010%5E2)
Rocks are created, the answer would be false
Copper plating is the process of plating a layer of copper electrolytically on the surface of an item. ... As the copper ions dissolve into the water, they form a coordination complex with salts already present. The copper then physically flows to the item, where it is reduced to the metallic state by gaining electrons.
