You should check A, and D.
Answer:
2090 J
Explanation:
the work done to move the cart is equal to the product between the force applied and the distance traveled:
In this case, the force applied is F=209 N, while the distance covered is d=10 m, therefore the work done is
Transfer of heat through objects touching source
Answer:
I do not know the answer because not all of the information is there.
Explanation:
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.
