<span>The fact that muscles will improve in strength and conditioning in response to resistance training is called MUSCLE HYPERTROPHY.
This occurs because during resistance training the muscles develop very small tears, called micro-tears, that eventually heal and become scar tissues. As the scar tissues continue to increase, muscle fibers are said to bulk up creating that big and muscular physique that you see in people who are into resistance training.</span>
The answer is either
b A system in which Newton's Laws are valid
or
c A system in which there are no external forces.
Explanation:
not a, and not d
There are energy changes in a closed system.
A closed system obeys the conservation laws in its physical description.
Answer:
166 cm
Explanation:
Given :
d1 =109cm
M1= 45kg
M2=29000g = 29 kg
As we know that Newton second law
![Force\ =\ Mass\ *\ Acceleration](https://tex.z-dn.net/?f=Force%5C%20%20%3D%5C%20Mass%5C%20%20%2A%5C%20%20Acceleration)
Here M1= 45kg
and acceleration=![9.81 m/s^{2}](https://tex.z-dn.net/?f=9.81%20m%2Fs%5E%7B2%7D)
Therefore
![F1=45 * 9.81](https://tex.z-dn.net/?f=F1%3D45%20%2A%209.81)
![F1= 441.45 N](https://tex.z-dn.net/?f=F1%3D%20441.45%20N)
M2=29000g = 29 kg
Similarly
![F2= 29 * 9.81\\ F2= 284.4 N](https://tex.z-dn.net/?f=F2%3D%2029%20%2A%209.81%5C%5C%20F2%3D%20%20284.4%20N)
Now we using the Principal of moments
![F1 * d1 =F2 *d2](https://tex.z-dn.net/?f=F1%20%2A%20d1%20%20%3DF2%20%2Ad2)
![441.5 * 109\ =\ 290\ *\ d2\\48,123.5=290 d2\\d2 =165.9](https://tex.z-dn.net/?f=441.5%20%2A%20109%5C%20%20%3D%5C%20%20290%5C%20%20%2A%5C%20%20d2%5C%5C48%2C123.5%3D290%20d2%5C%5Cd2%20%3D165.9)
~ d2=166 cm
The formula for density is ρ=m/v where ρ is density, m is mass and v is volume.
