The only force on the system is the mass of the hoop F net = 2.8kg*9.81m/s^2 = 27.468 N The mass equal of the rolling sphere is found by: the sphere rotates around the contact point with the table.
So by applying the theorem of parallel axes, the moment of inertia of the sphere is computed by:I = 2/5*mR^2 for rotation about the center of mass + mR^2 for the distance of the axis of rotation from the center of mass of the sphere.
I = 7/5*mR^2 M = 7/5*m
Therefore, linear acceleration is computed by:F/m = 27.468 / (2.8 + 1/2*2 + 7/5*4) = 27.468/9.4 = 2.922 m/s^2

Explanation:
Organic materials continue to be the largest component of MSW. Paper and paperboard account for 27 percent and yard trimmings and food account for another 28 percent. Plastics comprise about 13 percent; metals make up 9 percent; and rubber, leather, and textiles account for 9 percent.
Landforms pushing up mountains and hills. water and wind can wear down land and create valleys and canyons
Answer:
Strong cyber security is required when any personal information is transmitted through digital signals. There can be possible breach of information from the lines.
Explanation:
The digital signals are important and has made life easier in todays world. On the other hand it has expose humans to great risks of confidentiality breach. The personal information can be stolen through hacking by digitals technology which can be used for illegal purposes. Sometimes hackers even ask for ransom to release the personal information that is blocked.
