c)
Explanation:
From the question we are told that:
Diameter
Distance
Generally the equation for circumference of a circle is mathematically given by
Therefore
Angular distance that the pie plate has moved through in revolutions is
Generally Angular distance that the pie plate has moved through in radians is
Generally Angular distance that the pie plate has moved through in degrees is
Work done = change in PE = mgh = 60*10*4 = 2400 J
The correct answer is - continental tropical air mass.
If an air mass forms over a land mass, than that air mass is of continental type. Depending on the location of the area where the air masses are forming, they can be cold or warm. In this case, we have an area that is warm, part of which is near the tropics, part bordering with them, thus we will have the formation of a continental tropical air mass.
This type of air masses is characterized by being hot and dry. That results in hot weather, usually with a period of drought, thus very dry. This type of air masses often cause lot of damage to the crops, but also can affect the human health, especially the elderly people.
Find the circumference first
The term that does belongs to a different group is Patella
Femoral, pelvic and axillary are veins in the body; The patellar is a tendon attaches the bottom of the kneecap (patella) to the top of the shinbone(tibia). It is a ligament that connects to two different bones, the patella and tibia. Patella bone is attached to the quadriceps muscles by the quadriceps tendon.
