Sewage treatment is a natural monopoly
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
John is a B.passionate criminal because he lies just for the heck of it. Hope i helped.
I would say A because the author explains on how masculine he looks and how tough he is but then it switches to him showing his affection for his wife and how he is actually soft inside.
Of course I can be wrong but hey I've never took the SAT's before
If a perfectly competitive business firm is a price taker, then: A. pressure from competing firms will force acceptance of the prevailing market price.
<h3>What is a perfectly competitive market?</h3>
A perfectly competitive market can be defined as a type of market that is typically characterized by many buyers and sellers of homogeneous products, and there is free entry and exit in the market.
<h3>What is a
price taker?</h3>
A price taker can be defined as a business firm that is operating in a perfectly competitive market and is generally required to take the prevailing market price for its homogeneous product.
In this context, we can infer and logically deduce that pressure from other competing business firms would force acceptance of the prevailing market price when a perfectly competitive business firm is a price taker.
