Answer:

Explanation:
From the question we are told that
Temp of first bolts
Temp of 2nd bolt 
Generally the equation showing the relationship between  heat & temperature is given by
   
Generally heat released  by the iron bolt  = heat gained by the iron bolt
Generally solving mathematically
      
      
       
       
       
Therefore  is the final temperature inside the container
 is the final temperature inside the container
 
        
             
        
        
        
Answer:

Explanation:
If the weight  is a linear function of the amount of fuel, the following correlation is fulfilled :

we solve the equation:

 
        
             
        
        
        
The speed of a proton after it accelerates from rest through a potential difference of 350 V is  .
.
Initial velocity of the proton 
Given potential difference 
let's assume that the speed of the proton is  ,
,
Since the proton is accelerating through a potential difference, proton's potential energy will change with time. The potential energy of a particle of charge  when accelerated with a potential difference
 when accelerated with a potential difference  is,
 is,
     
Due to Work-Energy Theorem and Conservation of Energy - <em>If there is no non-conservative force acting on a particle then loss in Potential energy  P.E must be equal to gain in Kinetic Energy K.E</em> i.e

If the initial and final velocity of the proton is  and
 and  respectively then,
 respectively then,
change in Kinetic Energy  
change in Potential Energy 
from conservation of energy,
              
so,

Answer:
At the lowest point in the oscillation, the momentum is zero. 
At the lowest point in the oscillation, 
Explanation:
Since spring block system is performing to and fro motion along straight line
So here we can say at the lowest position of its path the velocity will become zero.
So we can say that momentum of the spring block system is given as


Also we know that after reaching the lowest point the block will again go up towards its mean position
So at the lowest point of the spring block system the block will move upwards again
So this will accelerate upwards hence


 
        
             
        
        
        
Answer:
when the mass of the bottle is 0.125 kg, the average height of the beanbag is 0.35 m.
when the mass of the bottle is 0.250 kg, the average maximum height of the beanbag is 0.91m.
when the mass of the bottle is 0.375 kg, the average maximum height of the beanbag is 1.26m.
when the mass of the bottle is 0.500 kg, the average maximum height of the beanbag is 1.57m.
