Answer:
a) Angular speed(w) = 2.02rad/sec
b) 73J ( It is Inelastic Collision)
Explanation:
Given:
Mass=45kg
Length on each side = 1.5m side which is hangs vertically from a frictionless pivot at the center of its upper edge.
We need to calculate
(a) What is the angular speed and
(b) To know why the angular momentum conserved but not the linear momentum

Answer:
0.99kgm/s
Explanation:
Given parameters:
Initial momentum = 5.8kgm/s
Final momentum = 6.79kgm/s
Unknown:
Magnitude of the impulse applied to the baseball = ?
Solution:
To solve this problem;
The impulse applied to the baseball can be found by using the expression below:
Impulse = Final momentum - Initial momentum
Impulse = 6.79kgm/s - 5.8kgm/s = 0.99kgm/s
Answer:
Be and Cl
Explanation:
This pair will form an ionic bond because Be is a metal while Cl is a nonmetal.'
Ionic bonds are bonds between nonmetals and metals.
What diagram I can't find it.
I think the most appropriate comparison would be :
a wave on a pond is a mechanical wave which require a medium to travel.
This is a complete opposite of electromagnetic move which are very dependent on medium to travel
hope this helps
