Answer:
c. It refers to any government program that tends to reduce fluctuations in GDP automatically.
Explanation:
Automatic Stabilizer is nothing but any scheme or program that that tends to reduce fluctuations in GDP automatically. It is generally intended to stabilize the GDP of a nation.
For examples In cases of economic slow down, the government sells its ownership in public sectors undertakings like, railways, oil and natural gases, to private players. So, that government has some money to combat the slowdown.
Answer:
4.36 rad/s
Explanation:
Radius of platform r = 2.97 m
rotational inertia I = 358 kg·m^2
Initial angular speed w = 1.96 rad/s
Mass of student m = 69.5 kg
Rotational inertia of student at the rim = mr^2 = 69.5 x 2.97^2 = 613.05 kg.m^2
Therefore initial rotational momentum of system = w( Ip + Is)
= 1.96 x (358 + 613.05)
= 1903.258 kg.rad.m^2/s
When she walks to a radius of 1.06 m
I = mr^2 = 69.5 x 1.06^2 = 78.09 kg·m^2
Rotational momentuem of system = w(358 + 78.09) = 436.09w
Due to conservation of momentum, we equate both momenta
436.09w = 1903.258
w = 4.36 rad/s
Explanation:
★A compound pendulum has an extended mass, like a swinging bar, and is free to oscillate about a horizontal axis. A special reversible compound pendulum called Kater’s pendulum is designed to measure the value of g, the acceleration of gravity.

<span>The part of the electromagnetic spectrum that is necessary for the sense of sight in humans is called visible light. This portion of the electromagnetic spectrum is composed of the various colors that the human eyes can distinguish. Each color has a corresponding wavelength. The human eyes can see wavelengths between 390-700 nm, and visible light ranges from 380-750 nm.</span>
