The source of the earth's magnetic field is found in the ;LIQUID MAGNETIZED IRON IN THE CORE OF THE EARTH. The earth's magnetic field is believed to be generated very deep down in the earth's core as a result of molten iron which it contains.
If a Ferris wheel has a 15-m radius and completes five turns about its horizontal axis every minute then the acceleration of a passenger at his lowest point during the ride is 4.11
.
Calculation:
Step-1:
It is given that the radius of the Ferris wheel is r=15 m, and the angular speed of the wheel is
=5rev/min.
It is required to find the angular acceleration of a passenger at his lowest point during the ride.
The formula required to calculate the angular acceleration is,
.
Step-2:
Now substituting the given values into the equation to get the value of the angular acceleration.

The acceleration is towards upwards that means towards the center of the wheel.

Answer:
the easy way to describe this is to use a light as an example.
Explanation:
Voltage is pretty much the loop used to help use a lightbulb to emit light. Without voltage, we would be unable to use lightbulbs. This applies to much more than a lightbulb, but it's the easiest way to describe how voltage works.
Hello! :)

Use the kinematic equation below to solve for the height of the building:

Where:
d = distance, or height of the building (m)
a = acceleration due to gravity (9.8 m/s²)
t = time (seconds)
Plug in the given values into the equation:
