on the globe , the largest continent on earth , asia lies in between eastern and northern hemisphere. it is also known that country china comes in asian continent. hence we can say that china also lies in between eastern and northern hemisphere.
hence the two hemispheres are northern and eastern.
Explanation:
Given that,
The vertical motion of mass A is defined by the relation as :
At t = 1 s
x = 115.33 mm
(a) We know that,
Velocity, 
At t = 1 s
v = 18.94 mm/s
We know that,
Acceleration, 
At t = 1 s
(b) For maximum velocity, 
t = 45 seconds
For maximum acceleration, 
t = 61.8 seconds
Hence, this is the required solution.
B. Heat goes from the drink to the ice
Answer: Example 1: Consider a crate being pulled along a frictionless floor (while such a floor is very hard to find, this will still help us understand the concept and we can return to this situation later, after considering friction, and solve it more realistically).
Consider a crate being pulled along a horizontal, frictionless floor. A rope is tied around it and a man pulls on the rope with a force of T. T is the tension in the rope. What happens to the crate?
Before we can apply Newton's Second Law,
F = m a
we must find the net force -- the vector sum of all the forces -- acting on the object. In addition to the force T exerted by the rope, what other forces act on the object?
As discussed in class, in Mechanics, we can restrict our attention to "contact" forces and "gravity". That means gravity pulls down on this crate with a force equal to its weight, w. But the floor supports the crate. The floor responds by pushing up on the crate with a force we call the normal force. "Normal" means "perpendicular". We will call this force n; you may also encounter it labeled N or FN.
