The formation of lactic acid in human muscles is closely associated with intense exertion or activity, during which aerobic respiration that uses oxygen to produce energy cannot be able to match the demand of energy by the muscles.
The muscles therefore resort to anaerobic respiration for energy where pyruvate becomes a makeshift hydrogen acceptor rather than oxygen as happens in aerobic respiration.
Pyruvate accepts a hydrogen from NADH and becomes reduced to lactate or lactic acid while NADH is oxidized to NAD
which is crucial in the formation of energy that is then stored in the form of ATP which is used to re-fuel the muscles to keep them going.
Answer:
The force required will be "300 N".
Explanation:
The given values are:
Mass of object,
m = 300 kg
Acceleration,
a = 1 m/s
Now,
The force will be:
⇒ 
On substituting the values, we get
⇒ 
⇒ 
Answer:
Thus it moves 1.7 mm sideways
Solution:
As per the question:
Mass of the television, m = 25 kg
Height of the rubber pads, h = 1.0 cm = 0.01 m
Radius, R = 0.60 cm = 0.006 m
Horizontal force, F = 200 N
Shear Modulus of Rubber, G = 
Now,
To calculate the distance moved:
G = 
G = 
where
= distance moved
Area of 4 rubber pads, A = 
Now,

No the vector can never be shorter than one of its components
