Answer:
(1) A hot drink cooling to room temperature.
(2) The combustion of natural gas.
Explanation:
The spontaneous process is the process in which there is a release of energy and moves towards lower energy and a more thermodynamically stable energy state. All the natural processes are spontaneous.
There are two processes which are spontaneous in the given question are:
(1) A hot drink cooling to room temperature: In this, there is a decrease in energy and also it is a natural process and we know that all the natural processes are spontaneous.
(2) The combustion of natural gas: The fire is an example of an exothermic reaction. The combustion is a combination of a decrease in energy and an increase in entropy. So, this process occurs spontaneously.
Answer:
<h2>1.5 ohms</h2>
Explanation:
Power is expressed as P = V²/R
R = resistance
V = supplied voltage
Given P = 600W and V = 30V
R = V²/P
R = 30²/600
R = 900/600
R = 1.5ohms
magnitude of its resistance is 1.5ohms
Answer:
590 ohms
Explanation:
Let the resistance of each resistor be 'R'.
Given:
Equivalent resistance of the three resistors in parallel
Plug in the given values and solve for 'R'. This gives,
Now, the equivalent resistance of the three identical resistors in series is the sum of each of the resistors. Therefore,
As the question asks to round off to two significant figures, so we add 1 to the second significant figure because the number next to 8 is 5 which is greater than or equal to 5. So, the number becomes 590.
Hence, the equivalent resistance in series is 590 ohms.
