Mass
Explanation:
Inertia is essentially an object's tendency to stay in motion or at rest unless it is forced to do otherwise (pun intended). It only makes sense to me that mass would best quantify an object's inertia, because an object with more mass would be harder to move and/or stop from moving.
Answer:
1. Wave period = 0.962 s
2. Will absorb red and blue and reflect green
Explanation:
1.
The wave period is:

Wavelength is the distance between crests. So replacing the given information:

2. In simple words the color of an object is the light it reflects. A green object reflects green light, and the rest is absorbed (red and blue).
It occurs when energy is supplied or withdrawn :)
R(parallel) = product/ sum
50×30/50+30
1500/80
