The moment of inertia of the empty turntable is 1.5 kg? m2. with a constant torque of 2.5 n? m, the turntableperson system takes 3.0 s to spin from rest to an angular speed of 1.0 rad/s. what is the persons moment of inertia about an axis through her center of mass? ignore friction in the turntable axle.

the moment of inertia of the empty turntable is 1.5 . with a constant torque of 2.5 , the turntableperson system takes 3.0 to spin from rest to an angular speed of 1.0 . what is the persons moment of inertia about an axis through her center of mass? ignore friction in the turntable axle.

2.5 kg? m2
6.0 kg? m2
7.5 kg? m2
9.0 kg? m2

is the persons moment of inertia about an axis through her center of mass.

Option B

Explanation:

Given data are as follows:

moment of inertia of the empty turntable = 1.5

Torque = 2.5 N/m , and

Let the persons moment of inertia about an axis through her center of mass= I

So, Now, from the formula of torque,

So, from the above equation, we can measure the person’s moment of Inertia (I)

a high pressure system is a dense air mass that is usually cooler and drier than the surrounding air. a low pressure system is a less dense air mass that is usually wetter and warmer than the surrounding air.

in general, areas that experience high atmospheric pressure also experience fair weather. low pressure systems can cause the formation of clouds and storms. air usually flows from areas of high pressure to areas of low pressure..

we have been given a quadratic function and we need to restrict the domain such that it becomes a one to one function.

we know that vertex of this quadratic function occurs at (5,2).

further, we know that range of this function is .

if we restrict the domain of this function to either or , it will become one to one function.

let us know find its inverse.

upon interchanging x and y, we get:

let us now solve this function for y.

hence, the inverse function would be if we restrict the domain of original function to and the inverse function would be if we restrict the domain to .
