Classically, gravitational attraction is due to the masses of objects. It is inversely proportional to the square of the distances between the objects.
Magnetic attraction is due to the magnetism in objects which is due to uncompensated electron spins in certain atoms.  The force due to magnetism less easy to put into one equation than gravity since magnetic fields can have different shapes, but the simplest one (the dipolar field) is inversely proportional to the cube of the distance between the magnetic dipoles.
        
             
        
        
        
Answer:
distance = 21.56 m 
Explanation:
given data 
mass = 50 kg 
initial velocity  = 18.2 m/s
force = -200 N ( here force applied to opposite direction )
final velocity = 12.6 m/s
solution
we know here acceleration will be as 
acceleration a  = force ÷ mass
a =  =  -4 m/s²
   =  -4 m/s² 
we get here now required time that is 
required time =  ...............1
     ...............1
put here value 
required time =  
  
so distance will be 
distance =  ........2
    ........2
distance =  
  
distance = 21.56 m 
 
        
             
        
        
        
As per Einstein's theory of relativity, the closer the clock is to the source of gravitation, the slower the time passes.  Clocks close to massive bodies slow down.  The time difference between two events will be very large. Time difference between two clock ticks will take extremely large amount of period.
it is confirmed by tests of general relativity.
Black holes are strongly densed matter. the gravitational attraction influences the clock ticks. Atomic clocks run a little faster on aeroplanes , away from surface of earth. Very close to back hole, where attraction and gravity is extremely high, clock ticks so slow that time can be thought of as stopped...
        
             
        
        
        
Answer:
C. Metabolism
Explanation:
Although it is a process that we cannot visualize, we feel it daily in our day by day life. A clear example is when we consume food of any kind, each of these foods contains a reference amount of energy in kilocalories (kcal). These foods supply energy to the human body, this energy from food is used for different day actions, and much to maintain body temperature. When the human body is exposed to very low outside temperatures, the body is exposed to a considerable loss of energy in the form of heat transfer, so the person will begin to feel hungry so that the body needs calories from food to maintain body temperature at stable levels. Metabolism is essential in the human body, at the moment when the human being dies his temperature decreases because the metabolism stops working.
