Assuming you mean temperature 
Answer: The third law of thermodynamics
        
             
        
        
        
The force applied would be 1.05*9.8 = 10.3 N
the pressure is equal to F/a 
area will be πr^2 = 0.002826
thus pressure will be = 10.3/0.002826= 3644.72 N/m^2
        
             
        
        
        
To solve the problem, it is necessary the concepts related to the definition of area in a sphere, and the proportionality of the counts per second between the two distances.
The area with a certain radius and the number of counts per second is proportional to another with a greater or lesser radius, in other words,


M,m = Counts per second
Our radios are given by



Therefore replacing we have that,






Therefore the number of counts expect at a distance of 20 cm is 19.66cps 
 
        
             
        
        
        
Answer:
The magnitude of magnetic field at given point =  ×
 ×  T
 T
Explanation:
Given : 
Current passing through both wires = 5.0 A
Separation between both wires = 8.0 cm
We have to find magnetic field at a point which is 5 cm from any of wires.
From biot savert law, 
We know the magnetic field due to long parallel wires.
⇒ 
Where  magnetic field due to long wires,
 magnetic field due to long wires,  
  ,
,  perpendicular distance from wire to given point
 perpendicular distance from wire to given point
From any one wire  5 cm,
 5 cm,  3 cm
 3 cm
so we write,
∴ 
  
  ![B =\frac{ 4\pi \times10^{-7} \times5}{2\pi } [\frac{1}{0.03} + \frac{1}{0.05} ]](https://tex.z-dn.net/?f=B%20%3D%5Cfrac%7B%204%5Cpi%20%5Ctimes10%5E%7B-7%7D%20%5Ctimes5%7D%7B2%5Cpi%20%7D%20%5B%5Cfrac%7B1%7D%7B0.03%7D%20%2B%20%5Cfrac%7B1%7D%7B0.05%7D%20%5D)
  
Therefore, the magnitude of magnetic field at given point = 
 
        
             
        
        
        
Answer:
Yes , it is possible  for two different atoms of carbon to have different numbers of neutrons in their nuclei .
Explanation:
Isotopes -
Atoms of the element with same number of the electrons and protons , but differ in the number of neutrons , are called as the isotopes .
The isotopes of the element have the same number of protons and electrons , hence have the same chemical and physical properties .
Many isotopes occurs naturally .
In case of Carbon ,  
Carbon too have isotopes ,  
i.e.  
Carbon - 13 and Carbon - 14
carbon - 13 , have seven neutrons  
Carbon - 14 , have eight neutrons .
