Answer:
Answer is C.
Explanation:
To calculate the IMA for a wheel and axle, find the ratio of the larger radius to the smaller radius:
IMA = R/r
IMA = 9/3
IMA = 3
Neutron stars have been overtaken by GRAVITY ;)
Turbine, rotational energy, and electric generators are the correct answer for the blanks from the given options.
<h3>What is an electric motor?</h3>
An electric motor is a mechanism that turns electricity into mechanical energy.
The interaction between the motor's magnetic field and electric current in a wire winding generates force in the form of torque imparted to the motor's shaft in most electric motors.
An electric generator is physically equivalent to an electric motor, but it converts mechanical energy into electrical energy using a reversed flow of power.
The sentences describe how power generation works as;
All <u>turbines </u>work on the same basic principle of converting kinetic energy, generated through the combustion of fuels or from the movement of wind or water, into <u>rotational energy.</u> This energy is then used to drive an <u>electric generator</u> to produce electricity.
Hence, Turbine, rotational energy, and electric generators are the correct answer for the blanks.

Answer:
We can easily find out the beginning point of the line by using dot representation.
When it comes to position vector, it expresses the exact position of certain object from the starting point of the coordinate system.
The vector is a straight line that has a certain end which is fixed to its body.
The other end is linked with a moving point that tells an accurate position of that specific point.
Answer:
Rusting of irons
Change in molecular composition
irreversible change
Explanation:
chemical change Is an irreversible change so we will only observe permanent change
