1.The answer is; C

The geosphere is made up of the physical rocks (composed of metals and minerals) and magma in the different layers. These densities of these rocks surpass those of other spheres such as the atmosphere and hydrosphere.

2.The answer is; B

Destructive forces break down land. Weathering and erosion are categorized as slow destructive forces because they take many years for their effect to be perceptible to the human's scale. Quick destructive forces are forces such as earthquakes and tsunamis.

3.The answer is; B

The atmosphere on earth is mainly composed of molecular nitrogen at 78%. Oxygen takes up 21% and other gases found in the atmosphere are hydrogen, carbon dioxide,ozone, dust, and water vapor at 1%.

4.The answers that apply are ; A & B

The formula for gravity force is given by the equation.; F(gravity) = (G*m1*m2)/d^2 where G is the gravitational constant, m1 and m2 are the masses of the two objects, and d is the distance between them.

5.The answer is; C

The force of inertia is due to their celestial mass. The larger the mass the higher the inertia. Inertia is the tendency of a moving object to maintain a straight path without an external force applied to it. This, therefore, prevents the moon from being pulled into collision with the earth. Gravity, on the other hand, prevents the moon from flying out of its orbit and away into space.

Determine experimentally which rotational axis yields the maximum rotational inertia (i.e., moment of inertia) and which yields the minimum rotational inertia for the broom stick. Draw a picture of the broom stick with its axis of rotation for (i) the minimum rotational inertia and (ii) the maximum rotational inertia.

Step-by-step answer

P Answered by Specialist

the maximum is I₁ axis of rotation at the end

the minimum moment is I₂ axis of rotation at the center of mass

Explanation:

For this exercise we use the definition moment of inertia

I = ∫ r² dm

for bodies of high symmetry it is tabulated; In this case we can approximate a broomstick to a thin rod, the moment of inertia with respect to a perpendicular axis when varying are

at one end

I₁ = ⅓ mL²

in in center

I₂ = $\frac{1}{12}$ m L²

There is another possible axis of rotation around the axis of the broom, in this case we have a solid cylinder

I₃ = $\frac{1}{2}$ m r²

remember that the diameter of the broom is much smaller than its length, therefore this moment of inertia is very small

when examining the different moments of inertia:

the maximum is I₁ axis of rotation at the end

the minimum moment is I₂ axis of rotation at the center of mass

hello your question is incomplete attached below is the complete question

answer : The moment of inertial felt by someone ( J ) is greater that the moment of inertia felt by the motor i.e. J > Jm

Explanation:

Gear ratio G > 1

a) Determine the moment of inertia felt by the motor

moment of inertia felt by Motor = moment of Inertia at the armature

b) Determine the moment of inertial felt by someone who is rotating the mass by hand

moment of inertia felt by someone is = J

The moment of inertial felt by someone ( J ) is greater that the moment of inertia felt by the motor

In the experiment, you will study an oscillator called a torsion pendulum. in this case, the restoring force is the torsion constant of the wire that suspends the weight x and the inertial term is the rotational inertia of the suspended mass. you will compare the periods of a suspended sphere and of a suspended cube. the rotational inertia of a sphere is is = 110msd2, where ms is the mass of the sphere and d is its diameter. the rotational inertia of a cube is ic = 16mcs2, where mc is the mass of the cube and s is the length of its side. if the

$\dfrac{T_c}{T_s}= 0.381$

Explanation:

Given that

For sphere

Is = 110msD²

For cube

Ic = 16mcS²

D= S

We know that time period of torsion pendulum is directly proportional to the square root of the rotational inertia.

$T=2\pi \sqrt{\dfrac{I}{K}}$

$\dfrac{T_s}{T_c}= \sqrt{\dfrac{I_s}{I_c}}$

Now by putting the values

$\dfrac{T_s}{T_c}= \sqrt{\dfrac{110}{16}}$

$\dfrac{T_s}{T_c}= 2.62$

$\dfrac{T_c}{T_s}= 0.381$
