Describe how body composition is measured?​

Physics
1 answer:
RoseWind [281]2 years ago
7 0

Answer:

Dual Energy X-Ray Absorptiometry (DEXA) is used to measure body composition.  

Explanation:

As a standard method for body composition analysis, DEXA has high accuracy along with hydrodensitometry. Its advantage is that it can measure the body composition of bone density, body fat and muscle mass for different parts.

g When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel 3.2 10-15 m before
AnnyKZ [126]

Answer:

Time, t=1.07\times 10^{-23}\ s

Explanation:

Given that,

When a high-energy proton or pion traveling near the speed of light collides with a nucleus, it may travel 3.2\times 10^{-15}\ m before interacting.

Let t is the time interval required for the strong interaction to occur. It will move with the speed of light. So,

t=\dfrac{d}{c}\\\\t=\dfrac{3.2\times 10^{-15}}{3\times 10^8}\\\\t=1.07\times 10^{-23}\ s

So, the time interval is 1.07\times 10^{-23}\ s

The liquid pressure exerted in one direction only​
Wewaii [24]
The pressure exerted by a liquid on an object increases as we go more deep into the liquid and this pressure is called as hydro static pressure . if we consider a part of the static fluid then all the horizontal forces will cancel out while the vertical forces will add vectorilly and due to which a pressure difference is created . so as we go more deep the pressure increase .

Now pressure is a scalar so it does not depend on direction but when two objects are on the same level with respect to a reference level then the pressure exerted on them by fluid is always the same . hope this helps
