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%.
a) since a=0 therefore, friction force =0
b) friction = 59.5 × 1 =59.5 N.
c)maximum acceleration = 0.566 × g =5.54 m/s².
<h3>What is Friction force?</h3>
The force preventing sliding against one another of solid surfaces, fluid layers, and material components is known as friction. There are various kinds of friction: Two solid surfaces in touch are opposed to one another's a relative lateral motion by dry friction.
<h3>What is acceleration?</h3>
Acceleration is the rate at which an object's velocity with respect to time changes. They are vector quantities. The direction of the net force acting on an object determines the direction of its acceleration.
Hence, (a) since a=0 therefore, friction force =0, (b) friction = 59.5 × 1 =59.5 N, (c)maximum acceleration = 0.566 × g =5.54 m/s².

Its a chemical change. Think of it in a way of being able to change it back to its original state. You cant change something back to its original state if its a chemical change. You can however turn something back to its original state when it under goes a physical change.
