my name jeff hahahhahahahahahhahhahhahhahhahhah the correct a
Explanation:
Answer:
1.697s
Explanation:
We use the second equation of free fall under gravity as follows;
Since the ball fell freely, u = 0m/s, therefore equation (1) reduces to
Given that h is the total height the ball falls through in time t seconds.
However, according to the stated problem the ball falls halfway in 1.2s, this simply implies that the ball falls through a distance of 
in 1.2s. Hence we can write the following, given that 
;
We can now proceed to find the time t for which it falls through h = 14.112m as follows;
Answer and Explanation:
Internal Energy:
Internal energy associated to a system is the total amount of energy of a system excluding both the kinetic and potential energies as a whole for any external effects and is only accountable for any change in the energies of the system due to the internal order or states. It can be considered as that energy of the system essential to make it ready for any provided state.
Specific heat:
It is the specific amount of heat that is contained in a unit mass of any substance needed to bring about [tex]1^{\circ} rise in its temperature.
Entropy:
It can be defined as the degree of disorientation of the molecules or the extent of disorder of the system. It is the lack in thermal energy of the system to get converted into work (mechanical).
Temperature:
The measure of the heat intensity of a substance on a given standard scale.
