Explanation :
The heating curve shows how water changes from one state of matter to another based on temperature and the addition or removal of heat over time.
Initially, ice is heated until its temperature reaches
and changes to liquid state.
From the attached graph it is clear that until
the temperature will rise steadily. Here, the liquid begins to vaporize. Vaporization is the state of matter at which liquid state changes to the gaseous state.
So, E is the point which shows the gaseous state.
<span> Use the Law of Cosines, where you have a triangle with included angle of 145 degrees and sides of 16 and 18. You are then solving the equation: </span>
<span>d^2 = 16^2 + 18^2 - 2(16)(18)cos(145) </span>

Answer:
The percentage power lost in the transmission line if the voltage not stepped up is 50%.
Explanation:
Given that,
Current = 60 A
Voltage = 120 V
Resistance = 1.0 ohm
We need to calculate the power
Using formula of power

Where,I =current
V = voltage
Put the value into the formula


We need to calculate the percentage power lost in the transmission line
If the voltage is not stepped up
Then, the power loss

Put the value into the formula


The percentage power loss P''


Hence, The percentage power lost in the transmission line if the voltage not stepped up is 50%.
Answer: L can be expressed in terms of g and f as
L = g/(2πf)^2
