p=mv=(813kg)(17)= 13,821 kg m\s
2Ω. Based on the graph the resistance of the bulb is 2Ω.
Based on the graph of the image we can see there are a linear proportionality between the voltage and the current. So, we can modeling this problem calculating the slope of the straight line in the graph as follow:
We can write a formula of the form .
From the Ohm's Law we know that the resistance is directly proportional to the voltage and inversely proportional to the current .
From the graph we can see in the x-axis the values of the voltage and the y-axis the value of the current, with the points (x, y) = (2, 1) and (x₁, y₁) = (4, 2) marked in the graph, we can write:
We need to express the equation in the form :
R = 2Ω
B it’s basically a geological hole in the earth (depression in earth)
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.
