What is pure inelastic collision? |
|
Answer» thanyou so much my friends In perfectly inelastic collision,momentum is conserved i.e. (final momentum is equal to the initial momentum. ), But kinetic energy is not conserved (final kinetic energy is less than the initial kinetic energy.), and the bodies stick together after collision and start moving with same velocity. Collision in which momentum remain conserved but kinetic energy do not remain conserve is called pure inelastic collision |

At 4 degree Celsius ,the density of water is equal to |
|
Answer» 1g/cm^3 Water has its maximum density of 1g/cm3 at 4 degrees Celsius. When the temperature changes from either greater or less than 4 degrees, the density will become less then 1 g/cm3. Water has the maximum density of 1 g/cm3 only when it is pure water. 1 |

Derive projectile motion |
|
Answer» Any object projected into space or air , such that it moves under the effect of gravity alone ,is called projectile. Projectile Motion equation derivation – parabolaThe velocity component along X axis = V0x = V0 cosθ and the velocity component along Y axis = V0y = V0sinθ. Air resistance is taken as negligible. In the above equation g, θ and V0 are constant. ... y = ax + bx2 where a and b are constants. Sorry i can\'t complete it Any object which is thrown into air such that it moves under the effect of gravity only is known as projectile..In motion in x direction-Velocity=usin(tita) |
