Answer:
Explanation:
Time taken by stone to cover horizontal distance
where t is time, h is height of whirling the stone in horizontal circle, g is gravitational constant, Substituting h for 2.1 m and g for 9.81
= 0.654654 seconds
t=0.65 s
Velocity, v= distance/time
v=10/0.65= 15.27525 m/s
v=15.3 m/s
where r is radius of circle, substituting r with 1.1m
Therefore, centripetal acceleration is
<span>An object keeps the same amount of kinetic energy unless it speeds up or slows down.
Kinetic energy can be calculated for any moving object as long as the objects' mass and speed are known.
The unit used when measuring kinetic energy is called a joule.
Kinetic energy can occur in any direction whether up and down or left to right.
<span>
When an objects' mass doubles, its kinetic energy also doubles.</span></span>
Industrially biomass, living or recently experienced obtain fuel from biological material or by using other industrial purposes are related. Widely, with the goal of obtaining biofuels fibers with cultivated plants, heat and chemicals used to obtain the means of animal and vegetable products. Biomass, organic waste can be burned as a fuel composition. However, geographical impact modified with, coal, organic materials such as oil-free. Are usually measured by dry weight
I believe that they are called thought experiments.
Answer:
The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.
