When the image of a distant object is brought into focus of front of a person's retina, the defect is called: nearsightedness.
        
             
        
        
        
Your answer would be the;  <u>NET</u>  force on the object.   Refer to Newton's Laws of Forces and Motion.

Answer:
Radius, 
Explanation:
It is given that,
Magnetic field, B = 0.275 T
Kinetic energy of the electron, 
Kinetic energy is given by :


 
            
v = 1037749.04 m/s
The centripetal force is balanced by the magnetic force as :




So, the radius of the circular path is  . Hence, this is the required solution.
. Hence, this is the required solution.
 
        
                    
             
        
        
        
Energy
because once the light hits her eyes energy flows through her body so the answer is A energy
        
                    
             
        
        
        
Most geologists accept radiometric dating techniques as valid because radioactive elements decay at a constant and measurable rate.
Answer: Option C
<u>Explanation:</u>
Scientists prefer radioactive dating to carbon dating because it is more accurate in measuring.  The analysis depends upon the radioactive decay of radioactive isotopes of any matter in a given rock or soil.
The parent atoms and daughter atoms are compared while studying, and hence age can be calculated easily. Radioactive decay depends upon the given half-life of the atom, which is a constant and is known. So, it would be very easy to calculate the number of progeny atoms and parent atoms and find out their age.
