Answer:
C. Luster
Explanation:
Luster is a phenomenon which refers to the manner with which the outer surface of a mineral reflects light.
Depending on the mineral, the 'luster' can differ. For example, in some minerals, the surface appears to be translucent, while in others, the surface appears to be transparent.
There are different types of luster, but they are categorized majorly into two:
- Metallic luster (the surface of the mineral appears like the surface of a metal).
- Non metallic luster.
Answer:
F=480.491 N
Explanation:
Given that
mass ,m = 22 kg
Angular speed ω = 40 rev/min
ω =4.18 rad/s
The radius r= 1.25 m
We know that centripetal force is given as
F=m ω² r
Now by putting the values in the above equation we get
F=480.491 N
Therefore the centripetal force on the child will be 480.491 N.
