The net force on the bike and the rider is 120 N
Explanation:
We can solve this problem by applying Newton's second law of motion, which states that:
F = ma
where
F is the net force exerted on an object
m is the mass of the object
a is its acceleration
For the bike and the rider in this problem, we have
m = 60 kg is their combined mass
 is their acceleration
 is their acceleration
Therefore, the net force on them is

Answer:
The Force exerted on the student by crate will be 100 N.
Explanation:
As per the given Question student is trying to push the crate in right direction with the force of 100N.
And we know that, Newton's third law states that every action has equal and opposite reaction.
So from the Newton's 3rd law of motion it is very clear the student must be experiencing the same amount of force which he is applying.

b
  
Explanation:
From the question we are told that 
    The wavelength of the red light is  
     The width of the slit is  
     The distance of the screen from the point of diffraction is 
Generally the width of the central bright fringe is mathematically represented as 
         
 
=>     
 
=>    
Generally the width of the first bright fringe on either side of the central one is mathematically represented as 
      
=>   
=>
