Freezing, as at the begginning they could slide past one another so the substance was a liquid and then it turned into a solid where the particles are even closer together and they have strong attractions between them
Answer:
a)
b)
c)
Explanation:
From the question we are told that:
Initial speed of 1st ball
Mass of 1st ball
Mass of 2nd ball
Initial speed of 2nd ball
Final speed of 2nd ball
Angle of collision
a)
Generally the equation for law of conservation is mathematically given by
The final velocity is given as
b)
Generally the equation for law of conservation is mathematically given by
c)
Generally the equation for kinetic energy is mathematically given by
1st Ball
2nd ball
Therefore the change in the total kinetic energy of the two balls as a result of the collision is
Answer:
a result stating that a body totally or partially immersed in a fluid is subject to an upward force equal in magnitude to the weight of fluid it displaces.
Explanation:
the purpose of using a chemical equation is to know the reactants and products that occur.
reactants=starting material
products=end result
