Answer:
Hello your question is vague hence I will provide a general answer on the importance of : Waste reduction, rationalization of consumption, reuse, recycling as ways of preserving the natural resources
answer :
Waste reduction : when we reduce the amount of wastage on items we use especially items produced from natural raw materials we will help preserve the natural resource because they can be used to produce varieties of other items
Reuse and recycling of waste products help keep our natural environment healthy thus preserving our natural resources.
Explanation:
Waste reduction, rationalization of consumption, reuse and recycling are all ways of preserving our natural resources
Waste reduction : when we reduce the amount of wastage on items we use especially items produced from natural raw materials we will help preserve the natural resource because they can be used to produce varieties of other items
Reuse and recycling of waste products help keep our natural environment healthy thus preserving our natural resources.
Answer: neither accurate nor precise
Explanation:
Showing that it should be near 9.8 m/s and the trials aren't near that accuracy, I would say neither.
To solve this problem we will apply the concepts given from the circular movement of the bodies for which we have that the centripetal Force is defined as a product between the mass and the velocity squared at the rate of rotation, mathematically this is
Where,
m = Mass
v = Velocity
r = Radius
Our values are given as
Rearranging to find the velocity we have that,
Therefore the maximum speed can the mass have if the string is not to break is 29m/s
Answer:
See below
Explanation:
Torgue = f * distance basically ...so if you want to increase torque with same f then the distance ( lever arm) must be increased
