A magnifying glass is a simple microscope
The power delivered to the coil is 0.5 Watts
<h3>Resistivity of a material</h3>
The formula for calculating the power delivered to it is expressed according to the equation
Power = I²R
where
I is the current
R is the resistance
Given
Current = 0.500A
Determine the resistance using the resistivity formula
R = ρL/A
Substitute the given parameters
R = 10^-6*(25)/0.002²
R = 2ohms
Substitute
Power = I²R
Power = (0.5)²(2)
Power = 0.5watts
Hence the power delivered to the coil is 0.5 Watts

Answer:
D = 230.2 Km
Explanation:
let distance between seismograph and focus of quake is D
From time distance formula we can calculate the time taken by the S wave
From time distance formula we can calculate the time taken by the P wave
It is given in equation both waves are seperated from each other by 17.8 sec
so we have
sec
Putting both time value to get distance value
D = 230.2 Km
A "live" wire or "hot" wire is one that's energized. <em>(B)</em>
It doesn't matter whether it has electrical current flowing in it or not. If the live, hot, energized conductor has <u><em>voltage</em></u> on it, there is risk of being shocked if you come in contact with it.
20N•m or 20J. Work is equal to force•distance, and 5N•4m is 20N•m, or J
