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:Deforestation refers to the decrease in forest areas across the world that are lost for other uses such as agricultural croplands, urbanization, or mining activities. Greatly accelerated by human activities since 1960, deforestation has been negatively affecting natural ecosystems, biodiversity, and the climate. The UN’s Food and Agriculture Organization estimates the annual rate of deforestation to be around 1.3 million km2 per decade.
Explanation:
I don't know what your options are, but heat moves from the sun moves in 3 ways: radiation, conduction, and convection. I hope this helps at least a little
Answer:
Explanation:
given,
A woman can see object between 45 cm and 155 cm
glasses is 2 cm from the eye
to able to read a book distance = 25 cm
For the object distant apart
hence, D = - 0.653 m
For the object at the near point
hence, D = 2.02 m
