Answer:
Moment of inertia of the system is 289.088 kg.m^2
Explanation:
Given:
Mass of the platform which is a uniform disk = 129 kg
Radius of the disk rotating about vertical axis = 1.61 m
Mass of the person standing on platform = 65.7 kg
Distance from the center of platform = 1.07 m
Mass of the dog on the platform = 27.3 kg
Distance from center of platform = 1.31 m
We have to calculate the moment of inertia.
Formula:
MOI of disk = 
Moment of inertia of the person and the dog will be mr^2.
Where m and r are different for both the bodies.
So,
Moment of inertia 
of the system with respect to the axis yy.
⇒ 
⇒ 
⇒ 
⇒ 
The moment of inertia of the system is 289.088 kg.m^2
I believe a but none sound like they’d build a laser
Power=work/time
So,
Power =450/50=9watts
Answer: It formed when lava cooled quickly aboveground.
Explanation: Cause its right
organisms and water
Explanation:
Organisms and water contribute to both chemical and mechanical weathering . A form of weathering known as biological weathering is a derivative of both chemical and physical weathering.
- Weathering is the physical disintegration and chemical decomposition of rocks to form sediments and soils.
- Organisms are pivotal to both physical disintegration of rocks through their activities.
- Through their metabolic activities, they also releases chemicals that are used for chemical weathering of rocks.
Water is essential for weathering. It is used in alternate freezing and thawing, a mechanical weathering process to break down rocks.
It is used in rock hydrolysis for chemical weathering.
