Answer:
C is the answer
Explanation:
The pituitary gland also known as the Master gland controls and regulates secretion of most hormones, when taller people usually grow past expected height this is normally due to the Pituitary gland not properly regulating and it secretes too many growth hormones causing "gigantism."
- Unlike charges attract .
- like charges repel .
There are two types of charges
Namely :
On loosing electrons , a neutral body acquires positive charge .
On gaining electrons , a neutral body acquires negative charge .
The amount of charge present in a body , either positive or negative , is expressed in terms of an integral number of charge of an electron , which is considered the elementary entity of an electric charge .
Answer:
21544 N
Explanation:
Let the atmospheric pressure be 101325 Pa
The side length of the cubic box:
![d = \sqrt[3]{V} = \sqrt[3]{0.051} = 0.371 m](https://tex.z-dn.net/?f=d%20%3D%20%5Csqrt%5B3%5D%7BV%7D%20%3D%20%5Csqrt%5B3%5D%7B0.051%7D%20%3D%200.371%20m)
The area of the cubic box:
20 C = 20 + 273 = 293 K
180 C = 180 + 273 = 453 K
As the volume of the air inside the closed cube is not changed, assume the ideal gas law we have
Where P1 = 101325 Pa and T1 = 293K are the original atmospheric pressure and temperature. P2 and T2 = 453 are the new pressure and temperature after the cube gets heat up
The net force on each side of the box it its pressure times side area
