Answer:
The force is 
Explanation:
The moment of Inertia I is mathematically evaluated as
                
 Substituting   for M(Mass of the wheel) and
 for M(Mass of the wheel) and  for
 for  (Radius of wheel)
(Radius of wheel)
               
                 
The torque on the wheel due to net force is mathematically represented as
                       
Substituting  135 N for  (Force acting on sprocket),
 (Force acting on sprocket), for
 for  (radius of the chain) and F is the force acting on the sprocket due to the chain which is unknown for now
 (radius of the chain) and F is the force acting on the sprocket due to the chain which is unknown for now 
                      
This same torque due to the net force is the also the torque that is required to rotate the wheel to have an angular acceleration of  and this torque can also be represented mathematically as
 and this torque can also be represented mathematically as
                    
Now equating the two equation for torque 
                                  
    
Making F the subject 
                      
Substituting values 
                   
                        
 
        
             
        
        
        
Answer:
you need at least two out of the three to get any aenser
 
        
             
        
        
        
Answer:

Explanation:
from the ideal gas law we have
PV = mRT 


HERE  R is gas constant for dry air  =  287  J K^{-1} kg^{-1}


We know by ideal gas law



 for m_2 



 
WE KNOW 
PV = mRT
V, R and T are constant therefore we have
P is directly proportional to mass




 
        
             
        
        
        
Answer:
Telescope
Explanation:
Telescope is usually defined as an optical instrument that is commonly used to observe the objects in a magnified way that are located at a large distance from earth. These telescopes are comprised of lenses and curved mirrors that are needed to be arranged in a proper way in order to have a prominent look. It is commonly used by the astronomers.
This was first constructed by Hans Lippershey in the year 1608.
 
        
             
        
        
        
A positive charge and a negative charge held a certain distance apart are released. as they move, the force on each particle increases
The most common charge carriers are the positively charged proton and the negatively charged electron. The movement of any of these charged particles constitutes an electric current
<h3>What is a Charge ?</h3>
When there are more or fewer protons in an atom than electrons, the substance has an electric charge. Protons have a positive charge, while electrons have a negative charge. If a substance has more protons than electrons, it is positively charged; if it has more electrons, it is negatively charged.
- The SI units for charge are ampere-second or coulomb. When one ampere of electric current goes through the conductor for one second, one coulomb of charge passes through it. Charge is denoted by the formula Q = I t.
