A 63 gm bullet moving with velocity 200 m/s. Collides against a wall consequently two third of it's kinetic energy is converted into heat. Than what will be the heat developed by bullet in calorie. (Given : J = 4.2)

A lead ball moving with velocity v strikes a wall and stops. iF 50% of its energy is converted into heat, then what will be the increase in temperature ? Specific heat of lead is s

A bullet of mass 10 gm moving with a velocity 210 ms^(-I) is suddenly stopped. If its energy totally converted into heat,How much of heat in calories would be generated .

A bullet of mass 5 g travelling with a speed of 210 m/s, strikes a fixed wooden target. One half of its kinetic energy is converted into heat in the bullt while the other half is coverted into heat in the wood. The rise of temperature of the bullet if the specific heat of its meterial is 0.030 cal/ (g - ""^@C) (1 cal = 4.2 xx 10^7" ergs") close to :

A bullet of mass 5 g travelling with a speed of 210 m/s, strikes a fixed wooden target. One half of its kinetic energy is converted into heat in the bullet while the other half is converted into heat in the wood. The rise of temperature of the bullet if the specific heat of its material is 0.030 (cal)/(g - ^@C) (1 cal = 4.2 xx 10^7" ergs") close to :

The rise of temperature of the bullet if the specific heat of its material is 0.030 cal/ (g - ""^@C) (1 cal = 4.2 xx 10^7" ergs") close to :

A 50 g bullet moving with velocity 10 m / s strikes a block of mass 950 g at rest and gets embedded in it. The loss in kinetic energy will be

When a bullet of 6g mass hits a target at a speed of 400m cdot s^(-1) , 70% of its energy is converted into heat. The value of heat generated is
