The answer is A. wood
because there are three different courts: clay court, grass court, and hard court. wood isn't in there so that would be the answer.
Answer:
B) What is the enthalpy change, ∆H, for this reaction? Show your work to receive full credit (5 points) The enthalpy change is 150. To find it we must subtract energy of products (200) & the energy of reactants (50) so 200 – 50 equals 150.

But heres the answer click the 3 dots on the question you made or you can ask a Moderator or Administrator to remove your question with a reason.
Energy is the ability to do work.
So work can not be done without the transfer of energy from one body to another.
Work is the transfer of energy.
Answer:
the mass of the body is 0.02 kg.
Explanation:
Given;
relative density of the oil, 
= 0.875
mass of the object in oil, 
= 0.013 kg
mass of the object in water, 
= 0.012 kg
let the mass of the object in air = 
weight of the oil, 
weight of the water, 
The relative density of the oil is given as;
Therefore, the mass of the body is 0.02 kg.
