Answer:
Explanation:
Given
mass of ethanol 
mass of aluminium cup 
both are at an initial temperature of 
specific heat of ethanol 
specific heat of aluminium 
specific heat of ice 
specific heat of water 
Latent heat of fusion 
suppose m is the mass of ice added
Heat loss by Al cup and ethanol after 
is reached
Heat gained by ice such that ice is melted and reached a temperature of
Comparing 1 and 2 we get
Thus 23.65 gm of ice is added
Newton's third law of motion is naturally applied to collisions between two objects. In a collision between two objects, both objects experience forces that are equal in magnitude and opposite in direction.For such a collision<span>, the forces acting between the two objects are equal in magnitude and opposite in direction</span>
Answer:
Buffers
Explanation:
A buffer solution is a solution containing weak acids and their salts or weak bases and their salts.
A buffer solution is an equilibrium system that resists changes in pH or pOH when a small amount of an acid or base is added hence it is a solution of fairly constant pH value.
The first thing you should know is that the friction force is equal to the coefficient of friction due to normal force.
Therefore, clearing the normal force we have:
The friction is 565N.
(565 / 0.8) = 706.25N. weight.
