Answer:
The trade winds, the prevailing westerlies, the polar easterlies.
Explanation:
There are three prevailing wind belts associated with these cells: the trade winds, the prevailing westerlies, and the polar easterlies (Fig. 3.10). Fig. 3.10 only shows the circulation cells and winds in the Northern Hemisphere
Answer:
The constant torque required to stop the disk is 8.6 N-m in clockwise direction .
Explanation:
Let counterclockwise be positive direction and clockwise be negative direction .
Given
Radius of disk , r = 1.33 m
Mass of disc , m = 70.6 kg
Initial angular velocity , 
Final angular velocity , 
Time taken to stop , t = 2.75 min
Let 
be the angular acceleration
We know
=>
=>
Torque required to stop is given by
where moment of inertia , 
=>
Thus the constant torque required to stop the disk is 8.6 N-m in clockwise direction .
Answer:
72 kg
Explanation:
The computation of the mass of the person is shown below:
As we know that
Water displaced weight = Raft weight + person weight
P_w.V = M_r + M_p
where
P_w denotes the water density i.e. 1000 kg/m^3
V denotes the volume of the water in m^3
Now
1000 × 0.224 = 152 + M_p
M_p = 224 - 152
= 72 kg
It is located through seven countries in South America which are Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile and Argentina. This is the Andes Mountains which is about 7000 km long. This is known as the world's longest mountain range.
