Answer:
2440.24 J
Explanation:
Moment of inertia, I1 = 5 kg m^2
frequency, f1 = 3 rps
ω1 = 2 x π x f1 = 2 x π x 3 = 6 π rad/s
Moment of inertia, I2 = 2 kg m^2
Let the new frequency is f2.
ω2 = 2 x π x f2
here no external torque is applied, so the angular momentum remains constant.
I1 x ω1 = I2 x ω2
5 x 6 π = 2 x 2 x π x f2
f2 = 7.5 rps
ω2 = 2 x π x 7.5 = 15 π
Initial kinetic energy, K1 = 1/2 x I1 x ω1^2 = 0.5 x 5 x (6 π)² = 887.36 J
Final kinetic energy, K2 = 1/2 x I2 x ω2^2 = 0.5 x 3 x (15 π)² = 3327.6 J
Work done, W = Change in kinetic energy = 3327.6 - 887.36 = 2440.24 J
Answer:
Explanation:
D)The system is open, and the net external force is nonzero.
The action which best illustrates a character vs. character conflict is: D. Mr. Hyde clubs and tramples the old gentleman to death in the street.
<h3>
What is a character?</h3>
A character can be defined as an individual or inanimate object that performs an action in a literary work such as a play and story.
<h3>
What is a character conflict?</h3>
In English literature, a character conflict arises when there is a physical altercation or fight between two or more characters, especially due to a misunderstanding or differing opinions.
In this scenario, the action which best illustrates a character vs. character conflict is when Mr. Hyde clubs and tramples the old gentleman to death in the street.
