This question involves the concepts of Newton's Law of Gravitation and mass.
The force on Procyon A from Procyon B will be "equal" to the force on Procyon B from Procyon A, which has a value of "3.75 x 10²⁶ N".
Applying Newton's Law of Gravitation, we can find the force on Procyon A from Procyon B, which is equal to the force on Procyon B from Procyon A:
where,
F = force = ?
G = universal gravitational constant = 6.67 x 10⁻¹¹ N.m²/kg²
m₁ = mass of Procyon A = 3 x 10³⁰ kg
m₂ = mass of Procyon B = (2.5)(3 x 10³⁰ kg) = 7.5 x 10³⁰ kg
r = distance between them = 2 x 10¹² m
Therefore,
<u>F = 3.75 x 10²⁶ N</u>

Cases A and B are all correct.
In Case C, the GPE is incorrect.
(But then, the power and HP have been correctly calculated
from the incorrect value of GPE, so we can't gig you too bad.)
Answer:
Technician A is correct while Technician B is incorrect.
Explanation:
If Technician a says that that both slip rings must be insulated from the rotor shaft, then, technician a is correct.
If technician b says that at least one slip ring must be grounded to the shaft to provide a complete circuit for current flow, this statement is incorrect because each slip ring must be connected to one of the three phases of rotor windings. And the slip ring brushes are connected to a resistive device ( like a rheostat). When the slip rings turn with the rotor, the brushes will maintain constant contact with the rings and transfer the resistance to the rotor windings. Therefore, Technician A is correct while Technician B is incorrect.

Where:
p = density
m = mass
V = volume
So to find the density you solve 36/16

Hope this helped. Have a great day!
Sure, if the mortality (death) rate is even higher than the birth rate.
