Three point masses of 2kg each are located on the x-axis at the origin, at x=0.20m, and at x=0.50m. Find the center of mass of the system? 25. A 15g bullet traveling at 500m/s strikes an 0.8 kg block of wood that is balanced on the table edge 0.8m above the ground . If the bullet buries itself in the block. Find the distance D at which the block hits the floor?

  the unit of the measure =

explanation:

  the property that is quantified by the energy needed per of material to raise the temperature by one.

  si unit of energy = joule (j)

  si unit of temperature = kelvin (k)

  si unit of mass of material = kilogram (kg)

the property that is quantified by the energy needed per of material to raise the temperature by one is called specific heat.

the unit of specific heat is

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
