Answer: The distance between the man and the plane increasing at a rate of 400ft/s
Explanation: Please see the attachments below
Answer:
0.027648 kgm²
Explanation:
M = Mass of disc = 1.2 kg
r = Radius of disc = 0.16 m
m = Mass of rod = 0.16 kg
R = Rod distance = 0.16 m
Moment of inertia of disk is given by

Moment of inertia of the three rods

The total moment of inertia is given by

The moment of inertia of the stool with respect to an axis that is perpendicular to the plane of the disk at its center is 0.027648 kgm²
Answer:
According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge.
Explanation:
Hope this helps you
The NUCLEUS is the center of the atom. it contains protons and NEUTRONS
protons have a POSITIVE charge
neutrons have a NEUTRAL charge
electrons have a NEGATIVE charge
The answer would be 9,940 K is the temperature of Sirius B.
