It is rectangle and it probably is a lake perhaps
To find the x component use the following formula, where Ф = theta = the angle 'a' makes with the x axis.
Answer:
Mass of the disk will be 2.976 kg
Explanation:
We have given force F = 45 N
Radius of the disk r = 0.12 m
Angular acceleration
We know that torque
And
So , here I is moment of inertia
So
We know that moment of inertia
So
m = 2.976 kg
Answer:
Superconducting materials can transport electrons with no resistance, and hence release no heat, sound, or other energy forms. Superconductivity occurs at a specific material's critical temperature (Tc). As temperature decreases, a superconducting material's resistance gradually decreases until it reaches critical temperature. At this point resistance drops off, often to zero, as shown in the graph at right.
Explanation:
