Answer:
120,000
Explanation:
Millimeters to meters calculation-
Multiply by 1,000.
120 x 1,000 = 120,000.
This is the correct answer and formula.
Hope this helps!
I think its d. but im not sure
C. Amount of oxygen
The others either change but don’t decrease or they increase.
Answer:
m = 35.98 Kg ≈ 36 Kg
Explanation:
I₀ = 125 kg·m²
R₁ = 1.50 m
ωi = 0.600 rad/s
R₂ = 0.905 m
ωf = 0.800 rad/s
m = ?
We can apply The law of conservation of angular momentum as follows:
Linitial = Lfinal
⇒ Ii*ωi = If*ωf <em>(I)</em>
where
Ii = I₀ + m*R₁² = 125 + m*(1.50)² = 125 + 2.25*m
If = I₀ + m*R₂² = 125 + m*(0.905)² = 125 + 0.819025*m
Now, we using the equation <em>(I) </em>we have
(125 + 2.25*m)*0.600 = (125 + 0.819025*m)*0.800
⇒ m = 35.98 Kg ≈ 36 Kg
Answer:
Explanation:
Given
mass of object 
kinetic Energy 
Tension in string 
mass is moving in a horizontal circle so tension is providing the centripetal acceleration
therefore 
where r=radius of circle
kinetic energy of particle 
divide 1 and 2 we get
