She is sad and feels left out because they are treating her badly. Hope this helps :)
Answer:
1.832 kgm^2
Explanation:
mass of potter's wheel, M = 7 kg
radius of wheel, R = 0.65 m
mass of clay, m = 2.1 kg
distance of clay from centre, r = 0.41 m
Moment of inertia = Moment of inertia of disc + moment f inertia of the clay
I = 1/2 MR^2 + mr^2
I = 0.5 x 7 x 0.65 x 0.65 + 2.1 x 0.41 x 0.41
I = 1.47875 + 0.353
I = 1.832 kgm^2
Thus, the moment of inertia is 1.832 kgm^2.

Three parts that make up atoms?
1;protons
2;neutrons
3;Electrons
Answer:
The support force/ Normal reaction force
Explanation:
Refer to Newtons third law.
"The third law states that when a force acts on a body due to another body, then an equal and opposite force acts simultaneously on that body"
Since we have a downward force acting on your object, in this case gravity/weight, there is an equal and opposite force given off by the surface the object is on. This is called the support force or the normal reaction force
