B. In step 3
They incorrectly solved for x. It should have been x=-3 and x=5
C because when the part gets out of the probe it would no longer stay contacted
Answer:
B. 1200
Explanation:
60 sec in one min in 2 min there will be 120 sec. 10x120=1200
Answer:
well the answers are 180 and 240 obviously
Explanation:
Answer:
Therefore, the moment of inertia is:
Explanation:
The period of an oscillation equation of a solid pendulum is given by:
(1)
Where:
- I is the moment of inertia
- M is the mass of the pendulum
- d is the distance from the center of mass to the pivot
- g is the gravity
Let's solve the equation (1) for I


Before find I, we need to remember that
Now, the moment of inertia will be:
Therefore, the moment of inertia is:
