Answer:
The price per kWh is
The energy density in watt-hours per lb is
Explanation:
From the question we are told that
The voltage of the battery is
The capacity of the battery is
The price is
The weight of the battery is
Generally the energy generated by the battery is mathematically represented as
Here P is power which is represented as
So
=>
=>
=>
converting to kW h
=>
=>
Generally the cost of this energy produced is Hence the cost of 1 kWh is mathematically represented as
=>
=>
Generally the energy density is mathematically represented as
=>
=>
A (b) would be 42 (c) from x to Y mark me as brainlist thanks
Option C is the sequence which correctly represents the displacement of the string as the pulses interfere.
