<span>when two hydrogen atoms approach each other the potential energy of the combination becomes lower and lower until it reaches a minimum value of -436 kl/mol at a distance of 75 pm</span>
Answer:
Correct option a. one state variable T.
Explanation:
In the case of an ideal gas it is shown that internal energy depends exclusively on temperature, since in an ideal gas any interaction between the molecules or atoms that constitute it is neglected, so that internal energy is only kinetic energy, which depends Only of the temperature. This fact is known as Joule's law.
The internal energy variation of an ideal gas (monoatomic or diatomic) between two states A and B is calculated by the expression:
ΔUAB = n × Cv × (TB - TA)
Where n is the number of moles and Cv the molar heat capacity at constant volume. Temperatures must be expressed in Kelvin.
An ideal gas will suffer the same variation in internal energy (ΔUAB) as long as its initial temperature is TA and its final temperature TB, according to Joule's Law, whatever the type of process performed.
Answer: hello your questions lacks the required resistor values therefore i will provide a general answer using an example
answer : a) 14 ohms b) 0.86 amps c) 10.32 V
Explanation:
Assuming the resistors are : 3 ohms , 4 ohms and 5 ohms
Voltage source = 12V
<u>Assuming that the Resistors are in series </u>
<u>a) Determine Total resistance </u>
Req = R1 + R2 + R3
= 3 + 4 + 5 = 14 ohms
<u>b) Total current </u>
Ieq = V / Req
= 12 / 14 = 0.86 amps
<u>c) The Total Voltage over the entire system </u>
Vt = ∑ Voltage drops
= ( 0.86 * 3 ) + ( 0.86 * 4 ) + ( 0.86 * 5 )
= 10.32 V
Answer:
Yes
Explanation:
Science is a quest to find answers and patterns in the universe which can then be relied on for predicting future occurrence. Finding these singular points or at least to some extent, the cause and formation of this point will help with our further and deeper understanding of the universe, and we can then be able to predict when, where or when this singularities occurs.
Answer:
No
Explanation:
Spending a lot of time on these singularities that are hidden from view behind an event horizon that prevents any knowledge about the singularity reaching the outside universe is an absolute waste of time. This reflects no practice of science, since science is all about finding answers. If these answers we seek to find no matter how much we probe, cannot be gotten from further studies of these occurrences then it will be best to leave what can't be found. The fact that all known laws of physics breaks down at these point is a pointer that any physical means that will be employed to probe these singularities will yield no result within our known physical laws.
I will go with yes, with hope that advance in science will someday break these barriers or reconcile our known laws of physics with whatever physical law prevails within these singularities.
