velocity of third bullet 
angles between guns is 
Suppose First gun is at 
and second is at and third is at 
therefore
conserving momentum in x-direction
as three bullets club together to become lump
Answer:
Adsorption
Explanation:
Sidewalk cooking of egg is very popular in America. In summer people release fireworks in night sky and cook egg on the concrete sidewalk to check the level of temperature. When sunlight fall on the sidewalk most of the light is reflected back but some darker material adsorbs some photon, and when these photons are transferred to egg molecules it causes vibration among them and produce heat and cook egg.
Answer:
Solubility increases with temperature.
Explanation:
-Increasing temperatures, increases the kinetic energy that allows solvent molecules to more effectively break apart the solute molecules.
-This solute molecules are held together by intermolecular attractions which weakens in higher temperatures.
-Solubility therefore increases with increasing temperatures.
