Being that Alaska is a state, it should be capitalized. You always capitalize a state name
Answer:
2000J
Explanation:
work done = force * distance
Work done = 100 * 20
Work done = 2000J
Current = (voltage) / (resistance)
= (12 V) / (2.5 ohms)
= 4.8 Amperes
Answer:
I = 2 MR²
Explanation:
Given that
Radius of the hollow ring ( hoop ) = R
The mass of the hoop = M
We know that mass moment of inertia of a hoop about its center is given as
Io= M R²
By using theorem ,mass moment of inertia at distance d from center is given as
I= Io + m d²
Here ,M= m ,d =R
Now by putting the values in the above equation we get
I = M R² + M R²
I = 2 MR²
Therefore the mass moment of inertia will be 2 M R².
Radioactive decay is used to determine absolute age.
