Answer:
Force exerted on the ball, F = -4900 N
Explanation:
It is given that,
Mass of the ball, m = 0.14 kg
Initial speed of the ball, u = +30 m/s
Final speed of the ball, v = -40 m/s (opposite direction)
Time taken, t = 0.002 s
Let F is the force exerted on the baseball. We know that the force exerted on an object is equal to the product of mass and acceleration. Using second law of motion, the force is given by :
F = ma
F = -4900 N
So, the force exerted on the baseball is -4900 N and it is exerted in opposite direction. Hence, this is the required solution.
To separate a mixture of salt and water, you can try first by using filter paper hen with the extra water part set it out to the window so that the salt water evaporates and only the salt is remaining.

Answer:
i) The reactants are sodium sulphate and barium chloride
ii) The products are barium sulphate and sodium chloride.
Explanation:
In chemistry, a chemical reaction occurs when one or more chemical substances usually referred to as REACTANTS undergoes some processes and is converted to one or more different substances known as PRODUCTS.
From the question:
Na2SO4 + BaCl2 ⟶ 2NaCl + BaSO4
The above balanced equation represents the chemical reaction between sodium sulphate and barium chloride. Both are the reactants because they where the substances that passed through a process ( this involves the breaking of bond that held them together).
The PRODUCTS are barium sulphate and sodium chloride because they are the substances that presented at the end of the chemical reaction.
